I have been facing problem with my Kaiser's GPS.
1. It takes me 40 mins ++ (max 1 hr and 20 mins) to fix signal.
2. After i fixed the signal, and after i close my garmin/mapking. it start from 0 again.....another 40 mins ++ to fix.
3. My quickgps is updated.
What is the problem? Could it be the hardward?
And, i have hard reset 4 times...and it still the same.
Btw, i have Garmin mobile XT and mapking installed.
Please advise. Thanks
There are lots of threads on these forums about the TomTom GPS - They've got a lot of info about configuring the set-up which may also be relevant to your Garmin - Look at the Wiki, stickies and try a search - best to use Mike Channon's google search set-up because it's better than the in-built one.
I use TomTom and I've noticed that the time it takes to get a fix will vary depending on which Rom I use, sometimes as long as 30-40 minutes, but normally within 1 minute. I've found that Sleuth's Rom seems to be consistently best for quick gps fixes - but this might just be coincidence that the weather and other conditions were always more favourable at the time.
I can advise the following which works for me:
1. Keep your quickGPS up to date.
2. Run gpsTest at least once to get the correct com port and baud rate for your gps chip.
3. Before you start your gps EACH time, run either gpsTest or VisualGPSce until they get a fix. (For some reason they fix much quicker than my Tomtom - usually seconds after the gps device is found).
4. After you get a fix with one of the above programs then you can start your Garmin program.
Good Luck.
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.
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!
Will try hard reset and install HTC GPS tool an try to fix
So it's become aware to me that for whatever reason, apps (GPS Photo, TomTom, Google Maps) are unable to get a GPS fix unless I first start up Chartcross GPS Test.
So first of all, why is this? Is the GPS Test software just tweaked to get a quick and dirty fix, or is it doing something that normal GPS software isn't?
Finally, do Windows Mobile devices run batch files? In desktop Windows I could write a batch file that, when run, would launch GPS Test PLUS whatever app I wanted, TomTom for example, and when TomTom is terminated, GPS Test is automatically ended. That would simplify this GPS quirk.
You could use MortScript (search here) to set up a script to at least do the startup part. I don't know enough about it to know if it could manage the shutdown part, too.
With regards to using GPSTest before your GPS apps it may be the case that GPSTest just does a better job of managing the GPS in the phone, but I think it's largely a placebo effect. Starting GPSTest before you start your nav program starts the GPS sooner, and you have a program actively seeking a fix for the duration of time it takes to then start the nav program and let it load completely before it starts looking for a fix. If you start that nav program when the GPS is inactive (no GPSTest running) you haven't even started that process until the program is fully loaded, so the initial fix takes a lot longer.
Well I have to disagree with the placebo thing, if I just startup TomTom alone with no fix, it takes at least 15 minutes to get a fix (I always give up), but if I start GPS test, it gets a fix within 20 seconds and then TomTom is fine.
No firsthand experience with TomTom software, so it may very well be that it just does a very poor job of handling the GPS interface. I can't imagine why that would be, but I'm no expert on how the phone handles the GPS integration either.
I know with Garmin Mobile XT and Google Maps it would often take a few minutes (up to maybe 6 or 7 minutes) to get that initial fix after a cold start, and I often felt like having GPSTest running made that shorter, too, but not by a terribly significant amount. The only explanation I can think of is that perhaps, on start up, these other programs only poll the GPS occasionally to see if it has acquired a fix whereas GPSTest maintains a constant connection. In its attempts to manage power the phone could be handicapping the GPS when it doesn't have a constant "listener" by powering it down. That's really just a shot in the dark, though...
The only thing that made a worthwhile difference for me was upgrading the phone's radio ROM. GPS fix problems are a thing of the past, regardless of the program I'm using.
My gps only stays connected for a couple minutes then it looses its signa. I have to soft reset to get the gps to work again. could this an atenna issue?
EDIT:
So after hard reseting again and trying again, I've discovered that sometimes the gps will connect but sometimes it won't. If the GPS won't connect, I have to soft reset multiple times until it connect again. Then if I soft reset again, it sometimes doesn't work. So obviously it isn't an atenna problem, but I've got no idea what type of problem it is. Help!

..which navigation program do you use?
Before the signal gets lost, will the screen be dark?
I have no problem with signal - 14 satellites even in the city (Prague) is nothing suprising...BUT! I'm experiencing quite big gps lag! :-( Tried lot of roms - stock WWE, tess v1.1-1.4, energy...same result - for example I'm driving through crossing but TomTom shows I'm at least 30m before it - it's about 1 second when I'm driving about 50 km/h...when I'm driving faster, it's much worse...especially when I was abroad that was really annoying
I use TomTom 7 but this problem also occurs with other programs like gps spot. My screen doesnt go black. Also sometimes my gps wont work even after a soft reset
lol, i have problem too - my gps works, but can't see any satellites
So has anyone found any sort of solution because GPS is kind of important and I use it a lot.
I use iGo. At first, I was also having problems finding a satellite. BUT ... after searching the menus in iGo, I found the settings for the GPS. like COm and baud rate. So what I did was to search the frequencies and it found something at DOM 4 etc. Every time I start iGo, I have to do that. Should find a menu for the GPS settings. Do an autoscan and enjoy. Hope this helps

Hmmm... iGO should memorize port and baud settings... Mine does...
I know it should. But every time I start iGo, the default is saved. That is, I think, port 1, baud 57660 I think :-?

In that case I would recommend to add the GPS settings to your SYS.TXT:
[gps]
set_messages=0 ;optional - this setting stops iGO from changing NMEA GPS protocol settings
port="4"
baud="38400"
will do. Thanks a lot!!!
After further investigation and a hard reset, I've discovered that the problem occurs because of TomTom 7. Can anyone recommend another GPS Navigation program?
iGo = I use version Nav N Go iGO 8 R3 - v8.3.2.83157 (Apr 3 2009), but there is Nav N Go iGO8 v8.3.2.91972 (May 28 2009) which also works fine
Has anyone tried v8.3.2.93112 (Jun 8 2009)?
poor gps signal
Hello
I have similar problem lately. I say lately because my GPS signal was perfect! It would have at least 5-6 satellites fixed inside home even driving on Manhattan was perfect never lost signal while dedicated GPS device like tomtom one would not have signal. But lately for about month I have problem getting signal inside home even outside is problem sometimes. for example when I update weather on HTC sense it wont be able to get my location, also google maps wont be able to get gps location inside home and after a few min of waiting it will get outside, another problem is Nav N Go iGo 8 V 8.3.4 Aug. 13 2009 version. similar symptoms wont get gps signal inside house and loosing signal while driving on a wide open area where almost no trees and no buildings around. the strange thing is device is in perfect condition never dropped and use same stock Rom ever since it came out same radio and same Hard SPL. I did hard reset few times re-installed radio but problem is still here. I would have blamed Rom or radio if I was not sure they ever worked in this case I'm very sure it worked perfectly with those software before why wont it work same way now? is this antenna problem? anyone ever had to open HTC pure before? is there a removable GPS antenna that could become loose or bad connection? any ideas?
