GPS Signal Never Saves????

Okay, Ive been using gps on my tilt for a while. When I was running WM6.0 on a 1.27 radio, my gps was perfect. Never ran GPS tool once, tom tom would aquire a signal within 20seconds of boot and it would be great from there....until i flashed to 6.1.
After flashing to 6.1, i went with 1.64.06.04 radio, and now using 1.58.21.23 radio. It seems that every time I use gps after a period of a day or so, I have to reaquire a GPS sat signal. This process always involves me running GPS tool for about 2min before satellites could be aquired. After that, would Tom Tom pick up a signal at its normal time.
I feel like my Tilt isnt saving the GPS info...
And yes, I have run quickGPS many times, and my region is correct in registry.
THanks for any help!!

my thoughts exactly
same here there is no sub for a good radio
i dont like wm6.1 just for not beeing able to use wm6 radios
no one can do anything

That's strange
I have the same duddy's rom but 1.64.08.21 radio .
I just keep Quickgps updated .
I never use GPStools , i use my navigator destinator7 and it takes around 1-2 minute to fix.
luca

any other thoughts on this? is there anybody that has exprenced this problem or knows a solution? ive been trying different radios, and none got a fix as good as the 1.27 radios...

I agree, don’t like the wm6.1 radios gps preformance. It takes forever to get a fix. With 6.0 and the 1.27 radios I got a fix in 15-20 secs. Don’t know what the issue is but don’t like it being so damn slow.

*Hopeless* GPS after 6.1 Update?

I know this has been touched on before, but I want to know if this is a widespread thing or what - since the official 6.1 update, my GPS has been really poor, particularly on a cold start. In fact, every time I use it feels like a cold start these days, even though Quick GPS is downloading data regularly and always shows 6+ days.
Every GPS app is the same - Tom Tom, GPS Test, Google Maps, Live Search - I can be waiting up to 10, 15, 20 minutes for a fix. The only time it's quicker is if I've used the GPS recently, and even that is a bit of a black art.
I like running the official ROM and I'm happy with the update in every other way, but the GPS problem is driving me up the wall - am I the only one? Is anyone running the proper ROM and not finding their GPS impaired?
The weird thing is, I can watch GPS test picking up two, three, four satellites but it just won't lock...
This is with the WWE 3.28 ROM with the 3.28 SPL loaded (fixing the freezes under Hard SPL v1)... what's going on?

Usually, I've found the GPS lock time is Radio Based. Maybe try a different Radio.

The only thing that is going to get me off the DEATH V3.5 ROM is a newer Rom by this same person.
The GPS is the best that I have ever had...
The phone signal is the best that I have ever had...
The GPS lock is about 30 seconds after TomTom starts...
The battery life is phenomenal - (it takes about 24 hours for the phone meter to register correctly) but I had 79 percent battery life left after using the phone all day yesterday at 11 pm last night (unplugged it at 6 AM).
Obviously - your carrier, your radio and ROM and where you are in the world can affect your signal greatly - but at this point - for me - the DEATH V3.5 ROM and radio rock and will stay on this phone as I LOVE having no phone issues.

Ok, maybe I've not been clear here - I'm not wanting to swap ROM stories or compare radios, I'm asking if anyone else is experiencing severe GPS problems with the stock ROM, and stock radio.
Anyone?
This isn't "which ROM/radio is best for GPS", it's "did the HTC ROM break your GPS?"

I have never looked at the official HTC ROM for comparison but I had the same thing after updating to certain ROM (non-official) the only way around it I found (other than replacing the phone) is another radio. Its not a problem with the ROM at all my good man just replace the radio and you should see a quicker lock time
I use radio 1.64.08.21 ang get a lock after approx 10-15 secs

Well If you are going to be snippy about it. Never mind. Forget I tried to help.
Though You may be hard pressed to find someone who is using the Stock ROM, I believe most people are wooed by the magic of Leo26, ConfusedStu, dutty, and the other Chefs out there.

So you wouldn't say that quoting my post back to me as "...snip snippity snip snip..." was being "snippy" in the first place?
I'm not trying to pick a fight here, I'm just interested in whether this is a common problem or not. I know GPS performance varies between radios, but with this new ROM & radio the difference is pretty shocking, and given that HTC are expecting the whole world to have installed it, I was surprised nobody else seemed to have noticed. You're probably right, nobody here kept it for long enough to find out apart from me, but I like my phone to be "stock". I guess this is my reward.
The answer probably is to try another radio, but it's a funny old situation.

I'm using the new (WM6.1) stock ROM from HTC on my Tytn-II and haven't had any issues with GPS lock. I would say less than 30 seconds assumming it has a clear view of a good percentage of the sky. Fix time is the same whether I use TomTom, GPS Tuner, or the HTC-GPS Tool.
Ofcourse if I try and start-up GPS while indoors or in an area where buildings block more than 50% of the sky then the fix time can be much longer.

I had the same problem after loading the 3.28 Hard-SPL. Reverted back to stock SPL and GPS is lightening fast.
Are you using the stock 3.28 SPL or the new 3.28 Hard-SPL?
Did you run Kaiser Tweak? if you did I would Hard Reset and try GPS test.

Got exactly the same problemwith the htc stock 6.1 rom. Nothin to do with hard spl etc as neve used it - phone has always been htc branded.
it appears that although quick gps data is downloaded, it is not used hence taking a long time as it needs to download the almanac data frim the satelites instead of quickgps. Ive emailed htc, but i have NEVER had a reply to any questions ive a ked in the past.

I'm on the stock SPL - my phone is Vodafone branded so I was originally using Hard SPL (with which I flashed the original stock HTC Rom) and then flashed the HTC 3.28 SPL after I found I had freezing issues with the 6.1 update. Haven't touched the new Hard 3.28, but from what you say it's obviously not going to help. I did wonder if the mystery fix in the 3.29 SPL might have something to do with the GPS, but if it's working fine for you on 3.28 who knows.

That's how it looks to me too - looking at the signal levels in GPS Test etc, it's not obviously a problem with the radio performance itself, which makes me doubt that changing the radio will actually help (while it will no doubt screw something else up).

I was just browsing through an interesting thread here - http://forum.xda-developers.com/showthread.php?t=292178 - on how Quick GPS works (or didn't work for a while) on the Artemis. There's some interesting stuff there about how all this is supposed to work.
I'm really suspecting that Quick GPS is broken in some way in the latest ROM. If it were working, then the phone should always have the almanac data and this should be visible in the settings screens in Tom Tom and other gps progs as satellites it's expecting to be there, but for me - unless I've had a very recent lock - it's always blank. In other words, the data isn't there, regardless of what Quick GPS is saying.
And a good question would be - where should the data be? Quick GPS itself is stored in the \windows folder, but there's no sign of the "packedephemeris.ee" file mentioned in the Artemis thread. Does anyone know where we should be able to find it on the Kaiser?
Another question is what server(s) should Quick GPS be downloading from - in my non-functioning Quick GPS, the settings in the registry are as follows:
HKLM\\SOFTWARE\HTC\QuickGPS\0\0\IP > xtra1.gpsonextra.net
HKLM\\SOFTWARE\HTC\QuickGPS\0\1\IP > xtra2.gpsonextra.net
HKLM\\SOFTWARE\HTC\QuickGPS\1\0\IP > xtra3.gpsonextra.net
HKLM\\SOFTWARE\HTC\QuickGPS\1\1\IP > xtra1.gpsonextra.net
HKLM\\SOFTWARE\HTC\QuickGPS\2\0\IP > xtra2.gpsonextra.net
HKLM\\SOFTWARE\HTC\QuickGPS\2\1\IP > xtra3.gpsonextra.net
The three servers (xtra1, xtra2, etc) are also listed under HKLM\\SOFTWARE\HTC\QuickGPS\SNTP as Server 1, Server 2, Server 3 - does anyone see anything different on there working model?

Im having the same problem,
Running Dutty's 6.1 Dual rom. Once the ROM had installed I noticed that QuickGPS didn't work straight off the bat. I suffered long GPS lock wait times. I found a QuickGPS cab file which fixed QuickGPS but my lock times don't seem to have improved. Via GPSTest I get 3-4 within sight straight away, but they sit on red for ages perhaps a few more satellites with appear but again they'll all sit on red. until about 15 mins passes, then finally a fix.
Im sure my GPS responded quicker than that in previous ROM's. at the moment its not really effecting me and im really not going to go through another ROM change again to test.
Im already on radio 1.64.08.21 which is supposed to be the best out there. tut.
no idea about hard spl and all that business, not really sure what y'going on about.
Would also like to find a fix for this, as i've tried a few different methods of fixing with no luck.

So it's not the radio, which ties in with my hunch that this is more to do with Quick GPS. But my Quick GPS registry settings match those I've found elsewhere, and I've found the data - it's an "xtra.bin" file in the Windows folder, which also matches reports from working installs. And I'm having no problem with the whole downloading process, that's happening in the background (through Activesync) just as it always was.
So is there something in the actual Rom (and presumably the base rom used by Dutty) which isn't picking up that data when utlising GPS?

Well I think I read a few posts on Dutty's Dual ROM thread about QuickGPS not working straight off, but its a long thread to plow through to find out. S its entirely possible there's a good reason.
Hmmm

well I proved to myself im not inherently lazy I did a bit of searching around and found this little gem of a thread
http://forum.xda-developers.com/showthread.php?t=375172
it suggested that QuickGPS has a region setting in the registry
low and behold I checked my
HKLM\Software\HTC\QuickGPS\region
and it was set to US,
I changed this to say UK, I've not tested this but I think this might make a difference. I'll let you know whenI get the chance to play around on the way home from work. I usually try and get a fix on the 15 minute walk to my bus and dont get any fix at all, If all goes fine I'll be watching myself in Igo8 on the way home. Sad.

Hmm, fingers crossed for you, I just checked and mine it's showing "GB" though. So maybe your's should be GB (although that's not working too well for me) or maybe mine's wrong, and should be UK?

well I just popped outside for a quick test and Corblimey guvenor if Im not getting a fix in about 20 seconds.
Which is excellent to say the least since i was sat under a canopy of trees at the time and its grim as normal up't'north.
Id switch yours to UK, I didnt really think to try GB, but If its not working for you right now, I'd suggest trying UK.

I changed it to UK, soft reset, tried Tom Tom, no change. I then checked the registry and it had switched back to GB, so I changed it again, closed and reopened Quick GPS and redownloaded, back to Tom Tom again and.. no change. I don't think it's going to do it for me, maybe we have two different problems here..

Diamond Gps Sucks

I am so annoyed with HTC Diamonds GPS. It just sucks and doesn't work. I had earlier updated the radio to 1.25.06 and then it didn't work. Other members over here advised to switch to 1.25.05 and yet it doesn't work. I did a hard reset too but no luck.
Map King fails to work and Google Maps keeps on saying trying to seek Satellites and yet it just shows 0.
I am truly disgusted with HTC and will never again buy their products

Funny, I have a Diamond too, and my GPS works perfectly. Actually it's the best GPS I've ever seen. Flash 1.93 ROM, then use QuickGPS to download actual GPS positions and try again.
By the way, you're not trying to run GPS inside the buildings are you? Go out into the street and try there. GPS doesn't work inside.

Have you set manual settings in google maps?
This way:

I had a flat tyre on my Mercedes the other day! I am so annoyed with Mercedes!
I will never buy Mercedes again!!

you need out your battery from your phone and put it back after one minute.

GPS works perfect on my Diamond. Much better than some car GPS devices i've seen. Dunno why yours doesnt work. Maybe you are a noob?
Doesnt work inside buildings btw..

Mine also working fine with MapKing2007 and HTC GPS Tool....
BTW I'm setting it at 57600.... is this fine? or actually does this setting matter?

I am currently running Swift Rom v5 and yes i am trying the Gps outside. Regarding the settings in Google Maps, i have kept it to automatic. QuickGps is also updated.
I will try the battery thing and will set it to manual
Thx to everyone for their input,

As the "I will never buy a HTC again" threads are coming up in decent sequence, I would dare to see a system behind it if I would be a bad mood. Backdoor marketing at a glance?
My TD GPS is the best I ever had. Sat fix with a loox N560 and Navigon MB6 - 2 minutes waiting. Same with my TD: 10 seconds waiting.
nextavenger, sometimes the prob is not in your hand resp. on the table but between the ears or behind your eyes? Just a guess though ...

I have no problem with the phone. I own two iphones too. I am enjoying my Diamond more than these iphones. When i had picked this phone, i had never intended for Gps feature but moving to a new city all together, i figured the gps can actually help me.
I went through all the previous threads complaning about the Gps lag and gps problems before starting this thread. Its not only me who is facing a problem. I did a complete research before starting a new thread. I bought maps specially for this and if the device doesn't work out of the box, its kinda sad.

it is not diamond's problem, gps is great in there !

When I bought my TD the GPS worked perfectly. Then i start flashing various roms and radios, and began experience various problems. Hard to get fix, losing signal and a huge lag.
Finally i flashed the new official rom 1.93 with radio 05 and all my problems disappear. Now it works great. It takes only seconds to get fix and the signal is rock steady, and the lag is no worse than other gps units i have before.
Try Duttys newest rom, he has integrated the radio and rom in his download. He thinks that flashing radio and rom at the same time may cure the gps problem, and i think he is right.

I flashed dutty's latest rom,did a hard reset and my gps gets a fix in a matter of seconds.

for everyone who has gps problem, follow these steps and reset gps data:
1) remove battery for five minutes
2) install gpstest 1.04 and set it to com4 at 4800 baud
3) wait for a fix in an open space (about 3-4 min.)
4) exit the program and start tomtom (set it on integrated gps) or other navigation software and here you go!!!
These steps help everyone who has gps problem after installing, removing navigation softwares and works with every gps.
I hope this will help you. Bye.

Is it working yet ?

ok so i did this thing:
Flashed my phone using Swift's recent rom i.e v5.5
Hard Reset
Setup my phone
removed the battery for 10 mins
installed GpsTest
Loaded Google Maps
and voilla! its now working. Gps is locking fast too.

this is the best gps a ever had (except the SIRF in the XTEN until it quit on me)
from day 1 my gps worked fine with the usual lag. changed radio and flashed a custom ROM (see my signature) and no more lag.
i can guess looking at all the gps threads (i think there are more threads on this subject than threads on new ROMs) that there is a problem. i just don't understand why so many ppl has it and so many don't
btw, i am using iGO8.

Never had a problem neither with my Diamond. On the 1.37 ROM with .03 radio it took my GPS between 15 - 30 seconds to get a fix after a cold start. Which I think is already quite fast. Now on the 1.93 + .05 on a cold start I'm able to have a fix in 5 seconds more or less. I'm really amazed! I loved my Diamond already, now I love it even more

Pity you can't retract the heading of your thread....
My GPS works great also. No lag, fast locks.

You might want to download "htc gps tool". In that one you can do a warm reset on the gps, and that sometimes solves a gps problem.
Just dont run "clear storage" option in the program as you then have to restart, download quick gps settings, and restart again.
Greetings.

How to tweak to the maximum the Kaiser GPS?

Hello there,
I bought a week ago a second hand kaiser, and i noticed that it already had the hyper dragon IV lite rom flashed, so i told myself, all the hard work is done, go try some custom roms.
And I did, there was some lite ones, some plenty of softwares, some 6.5, but the thing i want from this phone is: THE GPS and the MP3 player, thos are the most important things for me, since i am all the time moving here and there, i really need them.
So, in order to be a more independant guy, i searched, and i searched again, i found some useful threads that made my gps work (because it almost wasn't working i bought it), and some others that made GPSTest display high bars on gps detecting but no fix at all (it also screwed my signal, and fu**** up my camera, and that's bad), all that by changing radio roms and trying.
And well i am very tired of trying again and again, feel just like if i was stuck in the middle of nowhere.
So, my questions:
Does the gps really work better on 6.0wm than the 6.1 and 6.5?
Does the gps really work better on stock roms than cooked ones?
Does the quickgps software really improve the speed to get a FIX?
How long are the bars your devices display when you activate your GPSTest soft? (i'm having a quarter max, and when i say a quarter, it is really the down limit of the quarter, it rarely go upper)
I have a tomtom 7.450 soft, and this thing is all the time saying bad gps reception (sometimes it even end up screaming no gps harware), is it normal?
So what software do you use for navigation?
I really don't care about cooked roms optimisations, fast and everything and all that, i want to be able to answer and emit calls, receive and send SMS, write some notes from time to time, and make GPS working great, wanna have a super fast fix.
I'm living at Brussel in belgium, living in the 5th floor, and testing my gps close to window, or i go to a parc 10 minutes away from home.
I am ready to try almost everything that can guis ALL of US to have a better GPS!

This works for me.

As I charge my TyTN II by putting it to bed in its cradle every night (which is connected via USB to my PC on the internet), it automatically updates its QuickGPS data so it's hardly ever more than a day old any way. Often times during a day while I've got an active data connection I'll also manually initiate a QuickGPS download. Interestingly, the HTC Official WM 6.1 'update' for my TyTN II broke this feature and QuickGPS wouldn't automatically update when plugged into its cradle - even manual updates didn't make a difference though as far as WM 6.1 was concerned.

I have version 6.032 which came with my HTC Branded TyTN II on an accompanying CDROM. It's still avail for purchase although for some crazy reason TomTom wont sell version 7 or even an upgrade to it so there's no official way to buy it except for on the devices it comes with. If you get hold of version 6 from TomTom on a device kitted out as per mine, it will work and work well - unless you have lead lined walls and heat reflective film on your windows in which case you'll only get good performance outside.

Similar priorities to me, the only true speed/performance related area I find important is GPS, reliability is the next preference and thats where the Radio version I'm using comes into things. I found that although 1.27.12.11 gave quick GPS fixes, sometimes when Pocket Media Player was playing a music or video file, it'd stall its playback while waiting for TomTom to get a fix. Radio version 1.27.12.32 fixes this and also gives quick GPS fixes. I have tried even newer radios (2 versions of 1.27.15.32) but alas as is with the case of many of the newer offerings, that was a step backwards in terms of GPS performance (at least here in the UK (/Europe?).
There is a section in the xda-dev wiki all about improving GPS performance if you haven't already found it.

I had tomtom 7 and the gps fix in that software was horrible for me. Even when google maps and gpstest had a good fix, tomtom would say "bad signal" or "no signal. I switched to igo which locks in after a minute and works perfectly. The other problem that could be affecting you might be the radio version. I had one radio that would make my GPS useless; it would never connect. Try changing your radios and see if that helps.

I had tomtom 7 and the gps fix in that software was horrible for me. Even when google maps and gpstest had a good fix, tomtom would say "bad signal" or "no signal. I switched to igo which locks in after a minute and works perfectly. The other problem that could be affecting you might be the radio version. I had one radio that would make my GPS useless; it would never connect. Try changing your radios and see if that helps.

I tried so much radios, i don't know what to try again ? I even tried some of the polaris radios ...
And like a i said i'll give Igo a shot too
Thank you for your interest, thanks for answering me
Edit:
Just flashed back to ROM Version: 1.56.405.5
Radio: 1.27.12.32
But gpstest cannot find the gps, and it stucks on com5 while scanning
And when i close GPSTest i cant launch it again

More than enough to go on

I don't understand what you're getting at. The precise setup in my signature works really well for GPS. If you flash all those components and aren't to far away from the UK, I imagine it'll work well for you - there's no harm in trying.
Well, seems that the guy who sold it to me cracked it, i'll give him a call, and may be switch to Igo or an old version of tomtom

The map for my 'old' version of TomTom was on special offer (Western Europe 6.75) so you may well pick up a bargain.
I dont have any film on my windows

I was just kidding about lead lined walls and metalised film covered windows (although many new cars these days have metalised windscreens, so if it doesn't work in your car that may be why).
Just tried this two, and i have no sound on the phone while calling, and no camera (screen remain black)

Thats because you've not read the relevant ROM Flashing wiki's and stickies enough to know that you must use a WM 6.0 Radio with a WM 6.0 ROM. I suggest you spend more time revising things in this area as it WILL be time well spent and you'll learn more about your device.

Well you needent. All the details of what works best (as far as stock components go) are in my sig and as Belgium isn't far from the UK, I cant see why it shouldn't work well for you also

You did read the part in the wiki about making sure you have a WM 6.0 compatible SPL version didn't you (SPL questions? section covers it well). Again, you need ALL the bits in my sig (note that I don't need or use GPStest under this WM 6.0 setup). I cant say how it'll go with other than TomTom 6 as thats all I've used apart from Google Maps which also works very well on this setup - you might want to try the free Google Maps for testing purposes if you have a data package from your network provider.
I got my current setup by flashing hardSPL 1 then the complete ROM shown in my sig (which came with 1.27.12.11 Radio originally) then upgrading the radio to 1.27.12.32, then flashing the HTC 1.93 spl (this last step shouldn't be necessary though if you think you'll be doing more flashing).

I'm using the official WM6.1 and the GPS lock is horrible. I can see it getting signal from a number of sats but it can take 10minutes to lock in sometimes. I've read some threads on the subject, and have tried Quick GPS and have aGPS off, but neither guarantees a quick lock.
I seem to recall WM6.0 was better but it was also using a different radio then as well.
Anyway, sorry nothing I can offer to help.

You mean like the setup in my signature? You do realise it's possible to go back to this if you read up here on xda-dev about how to do so?

I agree, short of trying a custom WM 6.1 ROM, with no guarantee of success or installing third party apps to 'help' the GPS work properly, IMO WM 6.1 is a lost cause as far as GPS is concerned.

I had the same problems with the GPS, what I've found to work is using a program called GPSToday. there are 2 programs, one is a today plugin, and the other is a program. I use the program, and it really makes a difference for me. If you do a search in the Kaiser software forum, you will find more information about it. I use it with TomTom software, i start GPS today a min or 2 before i start tomtom and i get a fix right away.

Well Well Well
Great News from Here
I Managed to get my phone configured exactly like yours, and god! It is damnly fast, i got my first fix within seconds, its almost unbelievable !
I had it configured like that when you first advised, but i forgot to downgrade spl, i suppose that was the cause of the malfunctioning.
I really recommend to everyone who have the same priorities, to flash back to Flying Kiwi settings:
ROM Version: 1.56.405.5
ROM Date: 08/28/07
Radio: 1.27.12.32 (better than 1.27.12.11 with WMP)
Protocol: 22.45.88.07H
SPL: 1.93

Man, you really were very helpful, thank you very very very much, and my kaiser is even faster with this settings.
If i can help by anyway send a pm please
This post should be made sticky for future information!
EDIT:
I have to Warn you Guys: In order to have the GPS working you have to follow this procedure:
Flash the 1.56.405.5 rom and then flash the 1.27.12.32 radio rom, and finally flash the SPL, otherwise GPS will not work, i just tested that

Did the Wm6.0 up/downgrade also resolve the precission of the GPS?
Iam now on WM6.1 WWE with radio 1.70.19.09 and hardSPL 3.56 with a realy fast GPS fix within 30 secs. no problems with that
But the problem is that I mention a little lag kind of thing when navigation with TT7 in my car. The Tomtom arrow is little bit behind with the reality it is usable though but if i connect it to an external sirfIII gps mouse it is more accurate.
So I wonder if you guys also have a slight GPS lag with WM6.0...

GPS Signal loss

I searched a found several posts that say that using GPS Gate will fix problems with signal loss on the GPS. My GPS worked perfectly under factor 6.0, started failing using 6.1. Does anyone have a real explanation for what is going on, and if there is a cooked 6.1 or 6.5 that fixes the issue without relying on running some other "fixer" program first?
From my investigation, it appears that the GPS just stops sending for long periods (often 30 - 45 seconds) and then sends a burts of several messages, and then goes silent again. Repeat and rinse. This obviously drives Destinator 6 MAD (although "visualgpsce" seems to get updates every few seconds. Don't know why unless that program is polling for GPS data instead of waiting for it to be sent).

I have this radio and have taken 2 hour trips with gps no issues, Even used the phone via bluetooth for about 20 mins during gps usage.. either radio, rom, or hardware issue.. Flash and test..
Ohh i'm moving you over to kaiser general
Peace,

Anybody notice whacky GPS performance late last week?
Me and a friend had the GPS totally fail Friday and Saturday (it said we were 100's of miles from where we actually were).
Now it's back to normal.
Satellite glitch?

bteljuice, joshkoss,
Thanks for the info. Unfortunately, updating factory 6.1 with the 1.70.19.09 radio didn't help. I'm not sure it's the radio - some programs work and others do not, while all worked fine under WM6.0. I am running Destinator 6, which loses the signal every 3 or 4 seconds for up to several minutes, and also VisualGPSCe, which works perfectly... - what software are you folks running?
Brian.

Abt ur GPS woes: not sure if it true
Google this "GPS System May Soon Begin Deteriorating"
There is alot of thread on this but cant seems to locate the offical source.
This might be 1 of the possible reason to explain how our GPS goes whaco at times.
