Assisted GPS and Tomtom problem - Touch Diamond, MDA Compact IV General

I noticed like most that the assisted GPS is switched off be default out of the box. I decided to switch it on today and while using Tomtom I noticed every 2-3 seconds the gps signal would come on and off. It was just as though the GPS receiver did not exist. I tried a soft reset without luck. As soon as I disabled AGPS, Tomtom functioned perfectly.
Any suggestion on what could be the cause or did HTC deliberately disable AGPS because there is some problem with it?
Thanks

could someone possibly swtich on their assisted GPS and let me know if it holds the sats with tomtom

Have just done as requested on my device (using Advanced Config to enable it) and can confirm I see identical results as you;
- Assisted turned OFF (out of box): works fine
- Assisted turned ON: works for a few seconds, "No GPS device", works for a few seconds, "No GPS device", and so on
Also, I have found that no matter whether the above is turned on or off I am unable to get a position fix indoors (ie. next to window) - something I believe A-GPS was supposed to be able to do?
Very strange.. not least that it is disabled out of the box? Ideas anyone?

I've just received my diamond so I haven't tried it outdoors yet, but I can confirm that it's practically impossible to get a signal indoors with a-gps on. I turned it on first, so haven't tried it when it was off. Other gps receivers didn't have that much trouble to get reception near the windows. Will test some more outdoors with gpstuner which shows some more info than tomtom.

I agree with you as well. Today I was using Destinator 7 and had the exact same problems. It's like instead of using sat navigation, it's using the GSM signal and thus the map moves every 100-200 meters after the car has passed. Once the A-GPS is off, the program is flawless

Where do I turn on A-GPS? Is it the same as QuickGPS?

Same problem I had when I tweaked with Advanced Config... quickly figured that was the cause and turned it off.
It's quite quick and acceptable with sat locking so its no biggie.
I also think that the program that comes with the diamond to download a map of the sats helps a lot more then agps.

testing on my D-nd with TT and Garmin

it will work if you set the baud rate in TT to 2400. Otherwise turn agps off and it works at the regular setting. Haven't really notices a difference in performance one way or another.

Thanks for the above tip.
Have just made the baud rate change, and will test whether or not it works for me on my way home this evening.
However what I can report is that I am unable to get any 'lock' indoors (however approximate - ie. TomTom is reporting the normal "no valid GPS signal"), this being one of the benefits I thought A-GPS brought (ie. using phone mast information to provide an approximate fix when normal GPS was unavailable / weak). Has anyone actually provided the "A-" is providing benefit???

Well, I don't get it. When you setup the internal gps on Tomtom Navigator 7, you set it to internal gps receiver i guess. Doing it this way don't give you the option to configure the baud rate or so.
Setting it up like this, and i guess this is the correct way, you can't use asissted gps. You can get a signal from the gps, but it keeps on dropping it.
Hopefully there will be a fix for this problem. Till now, if you completely disable a-gps, e.g. through advanced config, it all works perfectly.

GPS Fix Problems (official HTC ROM)

i have problems with Satalite FIX.
it can take mor then 10-20min (if at all) to get a fix.
i setup my GPS manualy to COM9 @ 4800.
i know (at least) one other user have a simular problem.
HTC, after some e-mails, say that if i DON'T use TomTom software, they can't help my with this isue.
any idea ?
thanks.
Fix
I had some problems with slow fix. I enabled the GPS applet in settings and it was configured at 33600, changed to 4800 and also in Tomtom and miomap settings configured to 4800, after that, very quick fix, on cold start less than 1 min, on warm start just seconds. Try it.
under, settings -> connection -> GPS ...
i set:
program tab:
GPS Program port = GPD9
hardware tab:
Port = com9
boud = 4800
access tab:
mark on the manage GPS Auto.
is taht OK ?
and allso on the navigation program i set manualy com9 @4800
Yep, that's my config and works right...
interesting... i have my settings as follows -
program tab:
GPS Program port = GPD1
hardware tab:
Port = com1
boud = 115200
access tab:
mark on the manage GPS Auto.
with these settings i get a fix in 30 sec to 90 sec...

After a sofreset? Probably not
The "warm reset time" in a GPS is not related with the Port number or the baud rates...but with its sensibility
SAme for me the GPS response can take up to 10 minutes.
I tried your setting Julioski and AriebK but it doesn't help?
In tomtom I don't see where to set the port and the baud speed can you help?
Any other ideas?
after configure the above settings, i get FIX, but after 20-30min of navigation... the FIX is gone, one more thing, i notice that my phone 3g signal drop allso, SR was nedded.

According to HTC the reason the GPS function was not enabled in the first place was a conflict with the GSM signal,anyway try manually setting your phone band to GSM and see if that makes a difference.(Settings,phone,band,select network type:GSM)
What radio version have you installed?
1.35, 1.38???
I have an HTC p3600 Trinity and have also just installed the newest ROM from HTC.
I downloaded the TomTom application from HTC, installed it and everything "seems" fine accept I cannot acquire any signals.
I have tried many of the different GPS settings from the GPS manager, but nowhere do I see a way to change what TomTom is looking for. There are 5 default gps reciever options... (builtin, bluetooth, wired, other bluetooth and other NMEA device) and I really have no idea what to choose if I have to input the settings.
Can anyone help?
Thanks!

Both the "built in" and "COM9" should work (and do for me).
Make sure you're in an open area, and give it enough time to acquire a signal (could take 10 mins).

i tryed that... seems that with GSM, it took much more time to get a FIX (if so)...
with GSM it get the FIX much faster, but stil... too much and it drop the signal without any reasone.

Maybe that's why ... sorry couldn't help it...
Are you sure there aren't any other factors involved (like heavy cloud cover, rain, , etc.?) or more than 3 days since last fix (not that this should take 15 minutes - this is more than downloading the whole almanach). Can you check if you have signal all the time, or if you keep loosing all satellite signal? Because if it looses all satellites, he has to start from the beginning with the fix, so it's in a loop until he gets proper signal.
Well there seem to be quite a few issues with the GPS,personally i'm using the Destinator 6 software ,and here is what i noticed ;
With the official HTC rom :
The software detects the GPS in about a minute and acquires a fix in about 3-4 minutes with the GSM on and a clear sky.
If i softreset the device then 1/3 times it won't find a GPS antenna and i have to manually reconnect and define the com port,it then takes apprx 5 minutes to get a fix.
The weird thing is that when i used Destinator PN i didn't have any of these issues .
Lately i've started using img-32424-mUn and i've noticed a definite improvement in both GPS strength and speed.
i did use following test rom, the gps response is around 1min.
RUU_Trinity_CHT_1.23.751.1_101_6275_1.29.00.11_108_Test.exe
however, by using offical rom whatever config the baud rate or GDP, required 8-10 to get the fix.
the problem is that it's not stable
one day i get a FIX within 1 min, next day after 20...
and 2 days later, not getting any FIX.
i tryed with GSM and 3g ...
i guess the radio (or the GPS part) isn't as we excpect it
sad that HTC dont want to support users that NOT use TomTom.
I think it would be useful if each of us told the others the type of GPS software they were using as it (The GPS software)seems to affect the time it takes to acquire a signal.
Also try using the GPS with and without the radio (Flight mode) and see if it makes a difference.
No GPS Signal & Icon
Hi! I've another problem. I've downloaded new ROM upgrade and Tomtom applications. After waiting for 10 minutes, my device says no signal received. I read from some forums we can adjust some variables but there is no GPS icon under settings\connections folder.
Can anybody help me! I have version WWE 1.23.405.

GPS fails to initiate ... help.

i cannot get the GPS to start working again in the GPS photo. it says the GPS failed to initiate.
anyone had this problem before?
any fix ?
QuickGPS is not updating correctly as well.
thanks.
eric
LOL, just posted my fix in another thread. Try this... Run Windows Live or Google Maps, keep it running then switch to your camera. Go to the gps photo section and it should now initialize within seconds. Take your picture then upload it to GPS Visualizer, seems to be very accurate!
still says cannot initialize the GPS service
Have you been fiddling with the settings in the External GPS control panel applet? It's known that changing them, even if changing them back, kills your GPS. Only a hard reset seems to fix it.

Bs.
A soft-reset does the trick
I can't get the GPS to work with ANY program. I have NOT messed with the external GPS settings because I read in more than one place that it can mess things up.
It worked the first day I got my phone (initiated with QuickGPS then tested working with Google Maps) but hasn't worked since then. Not a single program I have tried will work with GPS. QuickGPS seems to download (it reaches 100%) but then errors out.
Any suggestions?
.:Christian:.
The best way to get gps activated is by GPS Viewer. You can find it on Google. It is freeware (as far as I can remember). It has been discussed in this forum several times. Set gps (through GPS viewer) to be at COM4 and 4800 baud rate. Then turn on Google maps or Tom Tom or any other GPS using program and wait for up to a minute. Usually it takes less. Once it connects, it works like a charm. The gps part of the phone is excellent. It picks up from within the car, even within the house.
Yeah, I tried that. It never showed anything. No satellites, nothing. The other thing is that I have to soft reset once I try to use the GPS because it slows down my phone so bad.
.:Christian:.
Sherpa posted GPSInit on this forum, it is a very basic app that connects to Com4 at 4800 baud, nothing more. Try that, it should start the GPS. The minimize ( not exit, that closes the GPS) and run the software you want tom use the GPS. If that does not work, your unit may be faulty and you can try a hard-reset.
I tried GPSInit. It said it opened COM4 OK. After that I tried 3 different programs - Google Maps, Map4PDA and Pocket Streets. None of them showed any satellites or any GPS information.
I guess I can try a hard reset if that is my only other option. I have soft reset this thing so many times, I doubt it is going to work again w/o hard reset.
.:Christian:.
P.S. The thing is, I don't know what I did wrong. I did not go into the external GPS settings at all. I guess I can try that, seeing as how it can't hurt me anymore. I just don't want to go through this again every time I want to use the GPS.
After you initiate the GPS with GPSinit, does the red led start blinking on the right of the speaker? If not, your GPS is not working. If it does, do not exit or close GPSInit, since that will close the GPS. Just minimalize it and start another GPS using software, like GPSViewer. Go outside first, and wait a few minutes. The GPS should then get a fix. Then fire up Google Maps and see if it works. Google Maps has a GPS time-out that is too short, meaning you must have a fix with GPS Viewer before starting Google, or the app will time out before a fix is acquired.

Yes, the orange light starts blinking whenever I use an app that uses GPS. Thing is, it never acquires a signal. I have waited up to 10 minutes, sometimes longer.
Another interesting fact - before, whenever I would use a GPS app, the light would never stop blinking when I exited the app, like it wasn't releasing the GPS or something. Ever since I went into the External GPS app, at least now the light stops blinking whenever I exit a GPS app, restoring my phone to a usable condition. Before, the light would always be blinking and my phone would be very, very slow.
You didn't answer my question about what hardware port the GPS should be on. I know the s/w port is COM4.
Thanks,

No GPS reception

Can someone please help me?
I have tried these programs:
Tomtom 6
Tomtom 7
GPSdash
BeeLineGPS
WMMiniGPS
GPS tuner
Google maps
I'm using the latest TLR ROM. My GPS setting are default. Com4 Baud rate: 4800.
Here's the problem. The programs seem to find the receiver and seem to find the satellites. (10-15). But I can get absolutely no signal at all. Indoors or outdoors.
I'm getting quite desperate
Have you used any of the tweaks for GPS? I ask as I did but my signal kept dropping - so I turned the tweak off and now it is fine.
I would also suggest using the QuickGPS application to get the Satellite information quicker
I've tried disabling agps. Didn't help. And yes I have used QuickGPS... but no luck.
Any suggestions? : [

Was it the first try? When I tried first it was 6-8 minutes. Where do you try? In the outdoor?
Have you ever used it?
TB
Do you have correct setting "GPS is managed automatically" ?
When I set to GPS is managed manually, I could not found any way to power on builtin GPS. You have to check box "GPS is managed automatically". I think, it may be point of your problem
I had the exact same issue dude... TomTom 6 didn't work so I installed TomTOm 7... still no signal... even with QuickGPS ran...
Google Maps didn't work either....
I'm not sure what I did in the end... took out the battery, set GPS to 'let windows manage automatically' and ran Quick GPS again.. then run TomTOm 7, go to the 'GPS Status' screen which shows the sat signal charts and stand in a wide open area for 5 mins.. ever since then it has worked fine
all the best.
btw you have to make sure your system date and time are accurate coz otherwise it'll be searching for Sats with a wrong reference to the Sat almanac..
Yes, it's set to manage automatically. I've been trying to get a signal by the window, I left the device just sitting there for more than a half hour and still nothing. I guess I'll have to try longer while being outdoors. Hope it helps... but thanks for your help.
I did that too and it didn't work for me. You have to be outside for the 1st time GPS fix and make sure you run QuickGPS before that. Ohh yeah use TomTom 7 to detect the signal... I find that the most reliable somehow... and be sure it's configured to use the built-in GPS receiver...
I know it feels odd... I nearly sent my unit back for warranty because I was very convinced that the patch antenna was somehow disconnected from the chip. lol.
I had the same issue at one point, due to my fiddling and inadequate hacking attempts!
see if you can track down the HTC GPS tool (it's here on XDA somewhere, but i can't find a link at the mo) and run that.
Chipset should be set to Q7200 (yes i know its actually a 7201A but it works the same) and com port to com 4.
Tap the open port button and you should see the GOS info scrolling through the grey window in the program.
If you see nothing, check the external GPS settings
program tab should be com 4
hardware tab should be non and 4800
last tab should be ticked.
if you still get no GPS info scrolling through the gps tool, then it seems you have the same problem i did. Sadly, i had to hard reset it to get it working again, but it has been perfect ever since.
FYI, this started happening once i had turned aGPS on, and even turning it off did not work for me, so if you have to hard reset, i wouldn't bother ever turning the aGPS on again.
where's the option to turn aGPS on/off?
I just remembered how I resolved my issue... I put a SIM card in I had previously been trying to use it with WiFi (to update QuickGPS) but once I had a SIM in there, the GPS worked. Could it be because I'm now using aGPS? hmm...
you need to install schaps advanced config tool to get to the setting to turn aGPS on and off again.
it seems to be off by default btw.

I also kept lossing the GPS signal with this on every few seconds. So I turned it off for good
did you maybe install voip on your diamond? If so that's your problem there. Hard reset you diamond don't install voip en there you go.
It worked! Thank you all.... I had to sit for half an hour in direct sunlight but it was well worth it... I'm new to gps... do you have to do this with every new gps receiver or is this just another great feature from HTC?
I'm, having the same probelm here.
I'm on my second diamond as the first one (a HK version) had a fault with the internal speeker. On the First phone the internal GPS worked fine with both TOMTOM 6 and Google maps. The initial setup only took about 30 secs.
With the new phone (UK spec) I have tried TT7, TT6 and Google maps. I have also run quiick GPS, hard reset and enabling and disabling assisted GPS using the advanced config tool.
Is there anything else I should try or is this likely to be another hardware issue?
Solution To Gps Problem
if you installed VOIP you should hard reset...gps dead...:-( no other solution.
Help! My Diamond GPS reception is MUCH worse than on my Touch Cruise
Hi,
I've just got a Touch Diamond, and the GPS reception is absolutely appalling. I have hard-reset twice, after which I've done nothing except download a QuickGPS update, but still the signal strength and its ability to connect to satellites is completely inconsistent and unreliable, even outdoors. I CAN get a good signal occasionally, but it's very rare. Most often I get no GPS signals whatsoever, or else I get just a couple of weak greyed-out signal bars in TomTom.
I can lay my Diamond down next to my Touch Cruise (both have identical TomTom 6 software loaded from the same CAB), and the Cruise always launches the app faster, finds the GPS device faster, AND finds adequate satellites faster. The Touch Cruise has a lot of problems, but the one thing it has always been very good at is GPS, and it has NEVER failed to find adequate satellites in TomTom 6, even indoors. It always takes well under a minute to do so, too. It's surely not unreasonable to expect at least the same level of performance from the next generation of device. Why should the Diamond's GPS performance be demonstrably so much worse?!!
Nine times out of ten, my Touch Diamond will simply sit there for an hour or more with the TomTom status bar reading 'Waiting for valid GPS signal...". Quite often when I open the GPS configuration option in TT6, it shows absolutely NO SHRED of a GPS signal whatsoever, even outdoors. (My Diamond and my Cruise have identical GPS settings in both Windows and TomTom, by the way).
The annoying thing is that the Diamond's GPS HAS worked on a couple of rare occasions, and the signal strength has been at least as good as on my Touch Cruise. The Diamond is much worse at holding the signal however, and is totally and utterly unreliable for navigation. It certainly isn't the 'Ultra-sensitive GPS' that HTC's marketing promised - it's nowhere near as good as the GPS on the Cruise, which is the previous generation! The Diamond's GPS DOES work well on very rare occasions - it's just that 95 times out of 100, I'm not getting anything at all. This makes me wonder if it isn't a WM 6.1 compatibility problem or a conflict of some kind. It's almost as if Windows is having difficulty activating/waking the GPS fully. When (and if) it finally gets going, reception is actually very good.
I have also downloaded the HTC GPS Tool as someone here suggested, and it reveals the same results as TomTom - I usually get either no satellites at all, or I get two or three red satellite status bars and a message saying 'Fix not available'. It ALWAYS shows a data stream coming from COM4 though, so there doesn't seem to be any problem actually finding the GPS device. On the rare occasions when I have got a usable GPS signal, the HTC Tool then shows two or three red status bars and three or four green ones as well. During those rare periods, Google Maps can also find anything from three to ten satellites, even indoors. However, the next few times I try the Diamond's GPS, nothing will happen at all - it's suddenly as if all the satellites have fallen out of the sky.
By the way, would QuickGPS make ANY difference on the Diamond? As other have pointed out, aGPS is disabled on the Diamond by default. Aren't QuickGPS and aGPS the same thing? I don't know. But if so, surely the QuickGPS data is useless on the Diamond?
Does anyone have ANY idea how to make GPS on the Diamond work as well as it does on the Touch Cruise? Does anyone know why it doesn't already? Has anyone else done a direct comparison between the Diamond and another HTC device using the same GPS software?
I really like the Diamond, but it's incredibly frustrating that the GPS is unreliable to the point of being unusable. At the moment, I'm having to carry the Cruise for GPS navigation and the Diamond for everything else! Certainly not what I paid for. It should do this stuff straight out of the box. Since it doesn't, I can only assume my device is faulty so if I can't get it fixed by the weekend, I'm returning it for a replacement.
Thanks,
Rob.
P.S. Sorry for such a long post, but I needed to vent.
Hi there, I'm having the same problem as RH Photography.
All the programs are trying to communicate, but no fix at all. Once I got a fix, but only 4 sattelites, when in my car GPS BT had fixed to 9!

TD's GPS thread

Hi all,
Could you please, be kind and post you experience with TD's GPS...
Since I got my TD(4 days) I have not been able to test the GPS at all
I have loaded some soft that could help me here. ( I travel a lot between Korea and Japan). Cannot really use the phone here, but WIFI works great and I thought I would give the GPS a test run.....no luck YET..
TD's own: QuickGPS has downloaded(through WIFI) all the info and it is up to date......But how do I set up the GPS itself???
Phone did not come with preloaded GPS software so,I have loaded following soft on itnone of them would recognize the gps)
i.e. " no GPS found."
1.Google Navigator 3.4
2.GPSvp (http://gpsvp.com)
3.Effica GPS Utilities (http://www.efficasoft.com/gpsutilities/index_wm_ppc.html)
I would really like to test out the GPS here first.I am returning to EU (home) in october or november and I would like to use it there as well.
sorry for the bump
I tried the search...not just this forum but all of XDA.....I cannot seem to find one successful step-by step activation as of yet???
Nobody has internal GPS running on their TD??
Anyone?
Runs perfect and is good quality.
Make sure you let windows manage gps (in external GPS settings):
programport COM4
hardwareport none
and in last tap check the checkbox.
Programs find gps at Com4 at 19xxx baud.

Don't you have a problem with the static navigation? This behavior "drives"
me nearly crazy, because beside of that, the GPS in TD is superb...
On mine, no programs can access the GPS and the programs will lock and crash the phone when it tries to connect to GPS.
The onlt one that does not lock the phone is TomTom, but it wont connect to GPS.
I've tried combinations of the recommended port stttings, but I still get no GPS.
I have not activated A-GPS, so I don't know if the phone came with this already activated - how would I check this?
My GPS is a pain in the arse, From what i have read its because of the static navigation. So far it says i live in house number 20 when I live in house number 16 and when i'm on route I'm yet to hear a " You have arrived at your destination" because its accuracy is off about 50 metres.
Hopefully there will be a fix for this very soon.
can someone get me up to speed a bit? what is the 'static navigation' that i keep hearing about..
admittedly, i find sometimes the gps is slightly less accurate at placing my exact location compared to my old Trinity, but otherwise its worked great for me..

Hey, have you got installed TomTom 7? I'm running TT7 and when I select "internal GPS receiver" it connects perfect. I know this doesn't exist in TT6, but I can also get my GPS running in TT7 if I set it to use a BT receiver on COM4 at 57600 baud. (Assuming you didn't mess around with the standard GPS settings, like HTC meant them to be )
Google maps is using the selection of "use windows settings".

hi guys
Same problem here. AGPS is disabled. I have tried Garmin,TomTom, iGo and google. 95% of the time it can not lock onto the sats. Once in a while it will work fine. Last night it picked up the sats in my bedroom on the second story and this morning outside in clear sky it found 4 sats but with very low signal and could not give me my cordinates, gave up after 15 min.
I have tried GPS tools and even that won't lock onto the sats. Data is upto date with quick gps.
So is it the hardware problem or has it to do something with radio? It can't be faulty TD because there are a lots of people with the same problem, and why lots of other users have no problems accessing the sats?
How is your gps working?
hi
great going sofar...thanks to all. We still have no real answers.
Let's keep this one going.
Looks like GPS is an issue with TD.
( Other than GPS...I am loving this sweet phone )
Now I am trying different roms to see if it is related to that. Will let you guys know if find anything.
Strange, on all ROMS my GPS reciever just works perfect.
Almost the best piece of hardware on the device
As I mentioned in Another topic, I use the GPS for TrackMe, at the same time I am navigation via Igo, and at the same time I showoff Google Maps with GPS support.
It functions very well!
Did you get the GPS-Fix downloads? It speeds up a lot.
Yes got the gps fix downloads but still no go. Still have not lost the hope. I hope its not some hardware problem.
I was fed up messing with mine, so I did a hard reset, and its sorted ...... for now!
same as Paulus
I did a hard reset....and it works perfect. No other adjustments done.
Tried the TomTom, Tracky Pro, GPS VP, and the HTC GPS Tool....all work no problem...outside I get a fix within a minute sometimes seconds.
I think one of the quirks that the TD's GPS has is that, when it's in Acquiring Satellites mode it doesn't seem to spit out any sort of status. The first time I noticed that I thought my internal GPS wasn't working, since with my external Holux unit I can see the satellites which the Holux was trying to lock onto.
Whereas with the TD's built in GPS it just snaps from nothing to.. acquired. So it's hard to see wheter it hasn't gotten a signal because it's in a poor area of reception or not. Usually I'll just try and stay still till I can get a lock.

AGPS - any proof of it working/providing benefit? (new topic - pls read!)

Now please no groaning when you see this topic. I know the GPS has been hammered to death on these forums; this post is my vein attempt to see if one particular area of interest of mine has at all moved forward.
(let's also side-step the whole "does your GPS lag?" issue here too!)
(..and, for clarify, I'm referring to AGPS as in the use of the mobile phone network to 'assist' positioning by use of triangulation in areas of poor/no GPS reception, and NOT the use of QuickGPS to download current sat. info in an attempt to get a quicker initial fix)
I used to use TomTom Navigator v7.450; it worked (of a fashion! ) although one specific thing that never worked was that whenever AGPS was enabled (using AdvancedConfig or similar) TomTom would get a signal and then immediately drop it again.. on/off on/off etc.. the fix being to disable AGPS.
I must admit I'm suspicious about HTC having their stock ROMs with AGPS disabled by default - especially as this was initially a 'selling point' of the device and part of the sales blurb ("not only does it have GPS but really good GPS using AGPS".. oh the irony!) - have they themselves ever got it to work?!?!
Now TomTom Navigator v7.910 is out (have just installed it myself, currently waiting for an updated map to download). I have seen it muted that this now works with AGPS on the Diamond or maybe the Pro (ie. someone reports the above bug, yet claims it now works having moved to v7.910). Can anyone else confirm this? More importantly, can anyone confirm AGPS has given the Diamond any GPS-related benefit what-so-ever?? (ie. great if it doesn't stop TomTom working anymore, but does it actually improve it like it should?).
I'll of course try it out myself later today or over the weekend and report back.
Hope this makes sense.. cheers.
just tried TomTom 7.910 (9185) with AGPS enabled, and cant say i noticed much difference.
seems the same now with it enable or dissabled. Cant be sure tho, havent done a long journey yet.
Will update later/tomorrow.

Thanks for taking the time etc.
Interesting, because..
I've just taken a wonder outside and found I'm still getting the signal constantly being lost bug (looking at the screen that shows the sat. bars I have a good signal for a few seconds, then this goes and 'No GPS device' is displayed, then good signal back again and so on).
On this Diamond I'm using ROM 1.93.401.2 the the supplied radio (1.0.25.05), as I suspected this 'improvement' (potentially) noticed by you/others is more likely a result of a ROM/radio update and not a TomTom software update (guessing this AGPS bug isn't the first thing you try after flashing is it?).
Hmm..
nb. I'm using the exact same version/build of TomTom as you
hmmm... yeh, i'm going on a 60+ mile journey later, so will have a play.
Using Dutty's 3.4 ROM and Radio is BS14...
I thought that the whole point of AGPS is so you could help you get a GPS fix when indoors. Which I always thought was an unusual selling point when the entire purpose of GPS software is to help you find your way in the outdoors. Perhaps it could be more useful for those new tagging services that are popping up.
Anyhow I've been running a fairly recent version of iGo8 using Dutty's Rom 3.3 and 3.4 (both with that new radio).
With AGPS turned off, GPS signal is quickly attained and holds strong outdoors. Nothing indoors, naturally.
With AGPS turned on (via Duttys "AGPS Settings" utility), GPS signal is as quickly attained and flickers fully on then fully off, repeating constantly. When indoors, nothing at all.
So, with iGo8, AGPS seems to be a non-runner.
By the way, I once read that AGPS has to be configured to your particular mobile provider. Perhaps that's the issue?
Same here, with a-gps enabled signal drops constantly
after my journey yesterday, had the same problems as above.
tried with TomTom 7 and iGo8
I've never had any problems with GPS apart from slow getting a moving fix when the unit is physically very hot.
The main benefit of AGPS for me is that you can get your location on Google Maps within 1500m or so without enabling GPS.
It also proves A-GPS works.

Hmm, I think this is thanks to googles effort, not AGPS... Google uses Google Gears API which can position you by using basestations and SSIDs.
AGPS is correcting/updating the GPS data with actual almanac data sent from you mobile provider...

Same for me, anyone being able to use TomTom and AGPS without losing signal periodically?

Yeah Google Maps does this on its own without having AGPS enabled on the Diamond. I believe AGPS is supposed to be more accurate than 1000m - 1500m though.
Oh and I believe the way that Google Maps gets its position depends on your mobile provider. I used to get the message "your location is not available" constantly on my network but one day (simultaneously as the iPhone was released in my country), the location was available. So I believe that the network flicked a switch for this technology to work.
AGps and TomTom
Hi,
agps have need to run to:
1) Carrier to inform MobilePhone here is (Is a Base Station Issue)
2) Public information about position
On mobilephone if is enable i think is need to have different information, and tomtom have old pattern to process agps information.
With googlemaps have new process and can use.
With my diamond agps run (googlemaps)

Please, don't mix the Google technology and A-GPS. They have nothing in common.
Google maintains their own privately held database of GSM-cellids which GMM can query to determine your position based on the current cellid.
A-GPS is a technology where the GSM-basestation itself receives GPS-satellitedata and relays it to the device. With this additional data, the GPS-receiver in the device is supposed to achieve a faster fix.
Have fun!
a-gps works with 7.450
i remember once that it was taking forever for the satelites to be found yet is was updating my postion on the map constantly via a-gps (which im sure was enabled by default in stock rom as ive never changed it)
a-gps is useful inside because you usually have your phone with you and to find a route, you need gps
Apologies for my erroneous post.
I realised my error today when I installed Google Maps on an ageing Blackberry I had unlocked to play with.
Started it up and lo and behold there was my location....thought I'd better head back here to suffer my shame ...LOL
Thanks for the input guys.
So - in summary:
Even with later ROMS / radios / software applications, there is still yet to be seen any benefit from the Diamond (theoretically) having an A-GPS capability.
RUBBISH!!
I personally subscribe to the theory that there is a missing link between the A-GPS driver type software and an info feed from the likes of the network operator, ie. it's all very well it picking up info on the network but without a back-end database to translate this it's useless.
As far as purpose goes.. I personally think A-GPS sounds on paper to be a great idea. Not a replacement for GPS, nor to be used exclusively indoors, but a good aid/starting point. For example, if I'm sitting in an unfamiliar office in London and wanted to use TomTom to navigate me a route to where I want to get to, A-GPS could provide TomTom with a rough starting point. Similarly, I often find myself launch a nav program (when I'm lost!) and standing there for up to 5 mins waiting for a fix.. at least this would give me an approximation from which I could probably work out myself where I was from looking around me. In my mind when you first fire up TomTom on the Diamond A-GPS should simply put you in the right postcode and start doing its stuff while the GPS seeks out its signal, and not still show me as being either at Home or its last known destination. But in any event - it seems not to work!! Bugger!!
I thought that aGPS was also to help hold a GPS signal when in tunnels, canyons, heavy forest cover (ie.Redwoods in this area, many tower to well over 300 feet!) or any situation where the signal from the satellites may be impaired, or even blocked completely.
Im running Duttys 3.5 and with AGPS on I will get a signal for 10 seconds, then it goes for a second, then back for 10. then gone. Turned AGPS off and all is well.
I can confirm that AGPS does work, some parts here in Finland it works and someplaces it does that on off thingy. once when I was just playing with my tomtom it got signal where it would never get it without it. but mostly here it doesnt work properly so i disable it.
But in Helsinki (larger city) it works properly and helps getting signal fast beneath tall buildings.
But yeah it doesnt work in my hometown so its kinda rubbish here.
Maybe it has something to do with how new are nearby cell towers or something. dunno
In Trondheim, Norway it worked with Telenor and gave me a signal indoors, but when I use it together with TomTom the signal gets lost periodicly, really really annoying since "everything" is already there. Probably just something with the co-operation with the regular GPS or something?
I think i got it to run.
I use tt7.910 on diamond with htc 1.93 dutch rom
My mobile provider is mobistar.
I can get a lock inside, tough it's slow(ie not as fast as outside).
When I fire up tt7 the almanac data is showing in the satelite screen.
reg settings are:
