Hi folks!
I got those **** GPS problems with my TP and worked myself now several days through dozens of related threats. Unfortunately, there doesnt seem to be a "one-best-way" but several (even some contradicting) suggestions... - and no Wikipage so far
After playing now with a lot of suggestions (registry tweak, killing the logfiles, gpsgate / splitter, AstroGPSLauncher, some mortscripts, about 6 different RadioRoms and maybe all baudrates/config combos of 5 different navigation systems) i got now really stuck and kinda frustrated. (Read: Yes, i used the search function!) Maybe i should burn that device - OR - some of you share their GPS configs / fixes / history so that i / we can write together a comprehensive (hopefully leading to a working solution) wikipage
I would be highly interested in:
o Working solution yes or no?
o ROM & RadioROM
o Did u have GPS problems at all? Which ones? No Fix? Slow fix? inaccurate? Jumping around position / loosing the signal each and every second? Lags?
o Could you solve it?
o How?
I hope with some of those working configurations it should be possible to replicate a working device...
Thx in advance!
First feedback with working combinations (QuickGPS as standard not included):

Thanks to Sleuth for the standartisation hint!
Did you change your Navigating Software to the new ports of the comsplitter with the GPS Signal? I had the same secondly changing signal- no signal, but after installing comportsplitter and changing the settings of the Navigating sw to the new ports there is a constant strong signal there with no lag.... Using ROMeOS 1.51 Ger and Radio 1.02.25.19. I tried nearly all radios, but most of them cause a big battery leak (for my TP)

P.S. I have a fix in nearly 30 seconds, but only after clearing the gps cache with the htc tools. the first fix took about 45 Minutes, but now its at half a minute. I deactivatet agps as recommended in many threats in several forums, but i use quickGPS
Thx for your information! (Sure i changed to the new Comports *g*)
Using ROMeOS 1.60.1 and radio 1.02.25.28 i get a fix in under a minute, just by using QuickGPS included in the rom.
Same radio configuration with Da_G 2.03 (see sig). VisualGPSce can fix outside in < 1 minute. TomTom needed to be "kick started" by another pgm but could see the GPSID natively (gave the built-in gps option in device configuration). After omitting the Flags value=2 (GPSID driver is unloadable) in HKEY_LOCAL_MACHINE\Drivers\BuiltIn\GPSID then TomTom was able to warm start the GPS in < 1 minute as well without needing a "kick start".
Currently, TomTom updates the display 3-4 times/sec and has little if no lag (cross streets on map pass by at the same time as the car does at 40mph). The only thing I continue to suffer from is "speed lag" whereby TomTom doesn't track with the speedometer when I slow down to 0mph. This can result in the car display ending up in the intersection on the map when the car is stopped (then it "snaps back"). I'm going to see how TomTom 6.x deals with this so I can get an apples to apples comparison with my Tilt which didn't suffer from speed lag.
Could I suggest Standardizing our tests?
What's your initial fix time using VisualGPSCE outside with a clear view of the sky (no kick starting allowed, just fire up VisualGPSCE and start a timer)? Set VisualGPSce to COM4: at 115200 bps (speed doesn't really matter as long as its >4800).
The first time you get a fix on any given day should be the one you report as this will be the longest. The reason is that QuickGPS ephemeris data will be used which gives approximate satellite positions. Subsequent fixes (try it!) will be lightning quick because you will be using actual ephemeris data downloaded from the satellites which gives precise sky locations for the time duration that the birds remain visible.
I am using NATF 3.2 ROM and 1.08.25.20M1 Radio. I use OCN8 and it gets <1 minute fix. No changes done to comp port or baud rate. However, it takes tweaking got get fix for Google Maps in little over 1 minute. I do experience LAG on OCN8 though.
I used to use Elice RC2 and 1.08.25.20M1 ROM. LAG was very very minimal but took more time to fix.
Here's the installation cab for VisualGPSce btw. It's freeware.

Yep VGPSCE is a classic tool
http://dl.htc.com/downloadfiles/Rom...ned_Raphael_52.44.25.24_1.08.25.20M1_Ship.exe
I flashed this ROM and it works perfect for me.
my config (signature) fixes up under 15 seconds when moving, <1minute when standing on one place. QuickGPS disabled, PagePool 32MB
For me prior to updating my ROM I could not get a GPS fix no matter what I did. Some of the newer ROMs use new GPS Drivers. This must have fixed my problem. I tried others older ROMS and no Fix, I tried a few Radios and no Fix.
I'm using LantisOS Rom, and the .32 ATT Radio. My GPS works with AGPS enabled or disabled, it doesn't matter.
I still have some lag, but its not too bad.
Here is what I do to get a fix.
1. I use QuickGPS to download the data.
2. I Launch Chartcross GPS Test to get a fix usually in under a minute if I havent used it for awhile. If I used it earlier in the day i can get a fix in like 5 seconds.
3. I either close or minimize GPS Test and launch my GPS program. (Google maps, Live Search, & iGuidance all work for me)
P.S. I do not use HTC GPS Tool as I've never got it to work. I have VisualGPSce which is good for viewing some data, but it seems that Chartcross GPS Test gets a fix way faster.
I added a short, unprofessional Wiki Page so that we can collect this information more efficiently...
http://wiki.xda-developers.com/index.php?pagename=GPS Issues
Please feel free to add your data and improve the page in language, style, structure etc.
For me totally not understandable: The first evening i tried with Romeos 1.704 & GPS it was impossible to get a fix. I cleared cache with HTC GPS Tool and did all the other things, tried with visual gps, gps mouse, glopus and others but i didnt get a fix, even after running 3 hours in the night the sattelites remained red.
next day, when i tried to work on this problem in the same room, same place, i had a fix in a few seconds....

P.S. My Radio is version 1.10.25.25
I was starting to have problems with AT&T stock ROM (1.95.502.5 WWE) & radio 1.02.25.32. All I had to do was disable A-GPS, use quick GPS to download data and then use GPS test to lock on to the birds. Also I have noticed that it becomes a lot quicker to get a signal without a case. Using a metal case sometimes it would become impossible for me to get a fix.

I remember 2 things that are importand(that I dont know how to setup in the PRO):
1. how the GPs handles static situations(dont remember the name) but the lag i get when i'm static or in a slow motion(traffic) is exactly what happend when i changed my BT GPS settings back in the day.
it was called "[FONT=Verdana, Arial, Helvetica]Static Navigation" : will "freeze" the position at very low speed to cancel out the drifting resulting from the natura "inaccuray" of GPS - should be disabled for pedestrian use - see below for details[/FONT]
2. [FONT=Verdana, Arial, Helvetica]Track Smoothing : wrill smoothen the track to remove the "jumps" resulting from the natural "inaccuracy" of the GPS system (10/15 meters) - disabled by default[/FONT]
http://www.gpspassion.com/forumsen/topic.asp?TOPIC_ID=25575
Just got my Vario IV yesterday and quickly flashed mrvanx's Elite Project rc3 rom.
Stuck in traffic this morning I noticed that any gps app i tried would find the internal GPS, find satellites, lock, then disconnect. It kept doing this for any gps app.
I tried disabling a-gps and the problem vanished, all the apps worked properly and maintained a GPS lock for around 20 minutes.
Its been fine sofar since then...

no one know the NEMA codes to change the GPS's unit settings?
Vodafone Touch Pro
ROM: 1.90.162.5 GER
Radio: 1.02.25.19
I tried all
...tweaks with advanced config tool
...registry tweaks
nothing helped.
Switched to Navigon Mobile Navigator 7 (free download on their website inkl. maps for europe to test for 30 days) and thried that.
Works perfect. Bought it afterall...
GPS fix in about 3 - 15 seconds depending on the location (NO QuickGPS in use) // no more GPS lags.
Really strange...
after trying a lot of radioroms, tweaks etc. i decided to go back to the initial ROM of my t-mobile branded Vario 4: 1.02.25.19
Guess what? Instant fix. Great reception. No tweaking needed...
OK, battery life is worse than other roms... but GPS is fully working! The difference is not big - its HUGE! With all the other roms, gps was just unuseable (fixes around 20mins or never, disconnections each and every second etc.)!
This brings up a question: Did anybody research the gps related differences between several roms? It would be great to know why 1.02.25.19 is such a difference on our (t-mobile) device(s?)....
Hi,
first of all: I also have the GPS-fix-problem
Now my question:
In this Thread I found this link
http://wiki.xda-developers.com/index.php?pagename=GPS%20Issues
and at the bottom I found this link
http://wiki.xda-developers.com/uploads/JCEspi2005 GPS Lag Fix Raphael.cab
I installed this cab, but nothing has changed...so I'm wondering what this cab should have done? Or does I have to change something after installation?
pls help ^^
Greetings

BTW: I'm from Germany, sorry for any mistakes

I have just updated my ROM to "Dutty's WM6.1 Hybrid v2 5.2.19716/5.2.19700" and at the same time installed TomTom.
It can take quite a while to pick up a lock the first time the software is booted but if I close and open TomTom without rebooting the phone the second time is much quicker (almost instant). I have just tried rebooting the phone and it goes through the same slow process the first time tomtom is booted and then quick following that. Is this normal behaviour for GPS on the device (not holding GPS info when the phone is rebooted) or is it an issue with the ROM or Radio. If its the radio is their anyone in the UK who can recommend the best radio for battery life and GPS.
Cheers,
Michael

This is pretty normal for GPS especially on these devices. It takes a while to get the first fix after a reset, but subsequent ones are quicker.
You may be able to speed up this process by using the QuickGPS tool to download cache data of satellite locations.
Also, try and use GPSTest to get the lock first. Many people use the GPSTest application and keep it running in the background as it tends to keep a good lock on things.
Adjust the baud rate with GPStest.
cheers for the responses... i will try the GPSTest thing...
KDKobes: what change does adjusting the baud rate make? quicker to lock?
I'm running the new, stock 6.1 Rom, and the only criticisim I have of it is the really slow initial GPS lock. The first time I use it after a soft reset or reboot, it can take anything in the region of 10-15 minutes, which I really don't think is right - I'm positive the original Rom was better at this. Subsequent fixes are much quicker, but if you find yourself needing the GPS and you happen to have recently rebooted, chance are you'll be well past your destination by the time it picks up, which is not good.
Quick GPS appears to be behaving as it always has - whenever I check it has recent data showing, downloaded through Activesync as normal - but it's almost as if that data's not being used in this Rom.
I should mention I'm seeing this behaviour in both Tom Tom and Live Search... it always does get a lock eventually, so there doesn't appear to be a problem with the GPS itself. Has anyone got any insight into this?

The baud rate is used by the internal COM port to interface with the GPS controller. It is the same deal like the speed of a modem...2400....4800...9600, etc.
Honestly with the amount of data that a GPS passes (which is not that much) I don't know if it makes a difference if it is set low. However, I always set mine high because faster is better, right so, might as well.

Where would you even set that though? I played with GPS Tool for a while, but it appeared to forget whatever port setting I used next time it ran anyway, so presumably it only affects that session of GPS Tool, not the system as a whole. In TomTom there's no speed setting for the internal GPS either; it should all be handled by WM itself.

Yeah, I think that's right... you can set it inside GPSTest.
However, like I stated many people find that GPSTest gets the quickest lock and prefer to either open it first and/or leave it running in the background. I haven't used my GPS that much, but I do find that this works.
It at least allows me to see what is going on with the lock. If I start Google Maps it will either work or not with GPS, but not really show me what's going on. GPSTest will allow me to see if I have a lock or not and then open up my other apps for use.
I just realised, I'm talking about the HTC GPS Tool, while you're talking about GPS Test - which is that, the Chartcross one?
You should try IGO8

Hello!
I have experienced exactly the same problem as you have with TomTom.
I have both a "Tytn II" and a HTC Advantage (X7500).
When using TomTom on the X7500 the GPS takes time to fix a position, 15-20 min or more is not unusual after a soft reset.
Then when it has fixed the position it is EXTREMLY slow when it comes to calculating the route!
I live in Sweden and I often drive to Germany, and when calculating the route from Sweden to Germany it takes over 3 min to finish!
Then we have the issue with the struggling graphics, (Of course I have been told that TomTom has trouble with VGA displays, and I find that to be very true.) the map is very slow and sometimes it stops completly for a few secounds!
On my Tytn II however the map is not struggling the same way, and it calculates much faster then on the X7500, Why? I dont know!
X7500 is a much faster device so it beats me!
The GPS lock is however almost as slow on the Tytn II as it is on the X7500, no matter if I have used quick GPS to download data or not!
A few weeks ago I stumbled upon a navigation program called IGO8, I decided to try it, and believe me when I say that I will never go back to TomTom again!
First of all the GPS lock is almost instant with IGO8, from a soft reset it finds a lock within maybe 2 min at most! And then it seems that it somehow remembers the position and the next time you start the program it will have a fix in secounds!
Then it calculates much faster, I tryed to calculate the route from Sweden to Germany on my X7500 and it was finishes under 20 secounds! (Compare that to over 3 minutes with TomTom on the same device!)
It supports VGA screens, so the map floats much better on my X7500.
Next thing is that there is more maps for IGO 8 so it covers much more of "mother earth" if you want to navigate in a foreign country!
It also has 3D terrain, and can even show buildings in 3D! (Only works in some places!)
It has a very simple and logical interface that is much easyer to understand then TomTom, and it is skinnable and very customizable!
So if you are serious about having a great navi I would strongly recommend you to try IGO 8! I can promise you will not be dissapointed!
Oh and buy the way, I dont work for IGO either!

I have problems getting software on my O2 Stellar to recognise the internal gps. I've tried a couple of different programs (TomTom & GPSTuner) and also fiddled around with the com ports in both the software and on the Stellar (using the External gps app in settings) but still no recognition of the internal gps.
I caleed O2 and no one could help, in fact they didn't even know it had internal gps!
I've seen GPSTest mentioned a few times. It's not on my Stellar - where can I get it?
Am I missing something?
Help please!
Thanks

Get GPSTest here
You can either manually set it to a COM port or have it autoscan. I believe some ROMs identify it as COM3 and others COM4, so probably best to do an autoscan. It might take a few minutes to find it, and then another few to get a lock. But after that it generally starts up and locks within a minute or two (in my experience).
Hi everyone
I have spent a lots of hours searching for the answer to bad gps reception on diamond, through different forums.I was about to sell the diamond when I finally came with a solution and that is Hard Reset after each Rom flashing.
For a few days I could not get a gps fix, no matter what I did. I tried Quick gps, Gps tool , Google map, iGo8 and Garmin. Somewhere I read that it could be the Rom I am using. So today I flashed 4 different roms including Dutty's, bepe and panosha but no gps fix. Finally I did a Hard reset and viola, it found the satellites within 10 seconds inside near the window on all the different Gps softwares without any problem.
So here is the procedure:
***After a ROM flash finish the usual soft reset and stuff and then do a HARD RESET. Download the data through Quick Gps and your gps should work properly at its default settings.***
Actually I found that Diamond is faster than TYTNII for getting the Gps fix.
Now if the Cooks can find out what causes this behaviour so we do not have to do a hard reset after every new flash.
Please share the findings.
Cheers!!!
********* Ok I have been flashing all the new roms and Gps was not working even with the hard reset. Finally I flashed CT's Beta lite2 Rom, did a hard reset and viola Gps is working flawlessly for the last three days. This Rom is actually the fastest and very clean among all the other roms I tried ( no offence to all the other great Cooks ). Please try it and share your findings!
Well, now i know why i dun have GPS problems...
i hard-reset after each flash ... just a habit inherited while using artemis...
Hi, nice tip
When you had done a hard reset, is the GPS working fine after several reboot ?
It will be nice if someone on XDA or HTC find a solution
Yes its working fine since then and I have done several soft resets.
Fine here. The only thing that made the GPS not work for me was turning on A-GPS.
Doesn't work for me. I have changed my ROM to bElite 0.93, have done a hard reset, loaded quickgps data and still no fix after half an hour on the window.
Try going outside in the clear. If you get the fix then its the location of your window.
try using HTC GPS Tool, it fixed for me once:
http://forum.xda-developers.com/showthread.php?t=360477
install the cab, run it, then choose "Cold Start" let it run for awhile then try using your GPS software again.

HI, ... Hard Reset,- you mean reformatting the internal storage as well? - i've done hard reset but still the gps can't fix location- says in HTC GPS tool - Mode 2: Not Fix
thanks
Mode 2: Not fix...
And the sattelites numbers show just #? Or u can see actual sattelite numbers?
Reason I'm asking is, if you just see #... then ur GPS is scr###d up and the cold start could really help.
If you do see the actual numbers, but no reception bars, then you have to get ourside into the clear sky. Be aware that nowadays windows are protective for keeping the heat of the sun outside. At the same time it keeps GPS for 95% out too.

You haven't been playing around with the GPS settings in the configuration of 'external GPS'? The standard settings are: GPS program port COM4 / Hardware port = none with a baud of 4800. Access tab should have GPS set to be managed automatically. Also, you have not enabled AGPS in any way like with a registry key or the advanced config program?

solution for fix not vaible
the gps is broken ?
My problem is not the fix, but rather the lag and lack of precision while navigating...
I have more or less 5 seconds of lag, and the precision is awful...
If I use a BT external receiver connected to Diamond, than I don't have this problem...
It seems that the receiver is refreshing to less, or the communication between the receiver and the GPS software is too slow...

So far i dont have accuracy issue. i tried igo8 using bt receiver (SiRF III) compared it to the internal gps- it's just the same , internal gps loads even faster- In TomTom7- if i use bt receiver, some voice instructions is not complete unlike the internal gps which is flawless- maybe it's the rom/radio...
I don't have any problem
"Bonjour" (since I am french !!! )
I tried the GPS with TomTOM V7 = no problem
with garmin XT no pb
First idea
Within the programm window I have a "fast GPS" programme
Do you have this ?
Did you run it ?
Second idea
You should enable Agps in advanced config
On my diamond if I disable it doesn't work anymore
Third idea
Try to see if "GPS utilities" works
Google it it's a basic cab file for showing basic GPS (position, speed, elevation.... )
Let me know
Diamond FrencH Rom 1.37.406.1 FRE
Hi,
Like most people here, I've experience TomTom's lag. From my stock Touch Pro, I notice a 3-4 second lag whilst driving around 60km/h. I read the previously mentioned GPS tweaks for the Touch Pro and initially applied the tweaks, but only dividing the original values by 4 (eg. PollInterval went from 1024 to 256, etc.). This reduced the lag to 1-2 seconds whilst driving. After applying the tweaks by dividing by 8 (eg. PollInterval to 128) resulted in the same 1-2 second lag in TomTom whilst driving. Clearly, the GPS is no longer the bottleneck now.
Next, I planned a route and watched the Demo at 200% speed to see how fast I can expect TomTom to appear. The display refreshed every 1-2 seconds! Coincidence?! I was in Harvey Norman (huge electronics retailer with lots of demo units) and watched a route Demo on a TomTom standalone device at 200% speed. The display refreshed 2-3 times per second.
Hence, is it possible to increase TomTom Navigator's refresh rate on the Touch Pro? For example, by applying some kind of graphics configuration changes or something? Perhaps tweaking the graphics driver somehow? Or is it that the standalone TomTom devices have much better hardware and the performance we are seeing on the Touch Pro is about as good as we can expect it?
Any help appreciated!
Cheers,
Ledg3.
Any ideas? Anyone?
Just wondering. have you tried one of the newer roms that have the gps driver cooked in? i am using provens 1.06 and it seems to not lag as much (only tried it for about 15 minutes earlier today)
Hi ajmoncrief,
Thank you for your reply.
I haven't tried any ROMs at this stage as I received my Touch Pro just recently.
Is it possible to load the new GPS driver without replacing the ROM?
Also, does your new GPS driver lag less than 1-2 seconds whilst driving?
At the moment, I would be surprised as TomTom only updates my display every 1-2 seconds, even just by running a demo (and not relying on the GPS for input).
I'm not sure about a driver cab...I would assume that theres one floating around. Check out Da G's rom thread and qsqa's PROven's thread. I tested tomtom again this morning and I'm getting much better results now. I'm not exactly sure how fast/slow the screen refreshes, but it does do so in a timely manner. Im confident that it does do better than once every 1-2 seconds. (I only live 3-6 miles from everywhere I need to go and I dont have any out of town trips within the next couple of days) Maybe someone else can chip in on their thoughts here.
TomTom 7.9 slow refresh
I am having the same problem on the AMEO (X7500) and TomTom 7.9 - screen refresh is quite slow, every 2 seconds. Version 6 was running realy smoothly. Any ideas? Soft reset, restart, speed camera warning on-off does not change the refresh rate.....

Your position on the map is always going to be a second or two behind your actual position. There is no bottleneck or slowdown even if you set the GPS at 4800 baud. The GPS only sends out a position update once a second. This will also make the screen a little jerky. Most programs smooth out the jerkiness by assuming there will not be a huge change in speed and smoothly move you to where they estimate the next GPS position will be.
Some programs also cheat and estimate your actual position on the map, so it is very close to your actual position. You can tell, because in the city you will be shown going through the intersection when you make a turn. It will then jump backwards and then show you making the turn. One of the GPS programs I use to have did this, but I do not remember which one.
TT7 on my Kaiser (ATT Tilt) moves smoothly along, and is near dead on for location. There's no refresh problems.
TT7 on my Raphael (ATT Fuze) repaints the screen every 1 - 4 seconds, and my position is off by at least 100 feet. Even with tweaks, it functions pitifully compared to the Kaiser.
is everyone here using the VGA version of TT7 or the QVGA version meant for the Tilt?
there are different versions (vga and qvga)??????????
Have you tried Franson GPS gate? DOwnload the trial and create a virtual com port 2 and map the Com4 GPS multiplexer to virtual com 2 and then have tom tom look to com 2 for the GPS. I bet the lag goes away. I was told that the commercial GPS softwares look for standardized GPS info in which the HTC phones' GPS use a variation which causes lag problems.
tomtom 7.910 screen redraw problem
Yes there are different versions of 7.910.9185 blue, black qvga and there is VGA version. I have the problem with the screen redraw, not the general speed, which is better than 7450 for example for route calculation. Screen redraw on 7.450 version was running smoothly, so it is not the question of the GPS, but the maps form 7.910 are not compatible with the 7.450. Screen redraw problem is visible even in demo mode, at 200% of speed instead of the smooth ride you have a "slideshow" in 7.910 version

I was using 7.450 but i read that version was for qvga devices so i upgraded to 7.451 i know it seems stupid for a .001 update but that is vga not sure about 7.910 as i read that it was vga to and for the diamond if im not mistaken but you can try 7.451 if you want. look around for it also if the map works for 7.450 i don't think it will work for 7.451 or at least it did not work for me. so look for the files if you can't find them drop me a pm and i can tell you where to "BUY" them also i tried the gps reg tweaks and it did not seem to make it any better but i did not have a problem with the gps in the first place. hope this info helps
I've also experienced lag like what you guys are talking about... what I did was I disable all POI in preference so that nothing will show up and it seemed to be a lot faster... still has that choppyness... but much better than before... i hope this helps...
Anyone has this 7.450 Tom Tom VGA Cab? Thnx in advance

How sure are you about this solution? Have u tried?
If it works, it means TomTom is at fault here, and not HTC
But it also lags in Google maps....how would you explain that?
I am very curious if anyone has really tried this and can confirm the lag going away (and most important; make pedestrian mode usable)

Sadly the HTC really is fault here, not TomTom. I have a external SirfIII GPS module, and while TOmTOm still appears to redraw 2-3times a second, the lag goes away. And TomTom is very very accurate then. The Franson GPS gate doesnt solve anything with the lag. It might make GPS lokc quicker, but tbh it didnt help me much (using QuickGPS data). I get fast locks with both the built-in and the external GPS. The problem is between the data output and the chipset. Drivers should / or could solve it.
Problem solved!
Hello,
Yes I have been experimenting A LOT with TomTom. I have found out that what really slowes down the map redraw is the RADARS if they are inserted into the map directory as a POI. Without radars it runs very nice both in version 7.45 and 7.9.
TT redraws screen very slow even if you switch off the warning for getting close to the radars as POI categories, I think that it is much too many of them for the whole Europe and POI mechanism is not the proper one for radars. Changing the radars into the official "with serial" solved the situation. I hope it helps to the others!
Tom Tom Lag
Aside from the initial startup (I wait about 30 sec) everything seems to work well. Refreshes good, etc.
I use the following settings:
Ver: TTN_7.450.9028
Map Pack: USA_and_Canada_v.675.1409
Other NMEA Device
Baud 19200
COM 4
HTC Radio: Raphael Radio 1.08.25.20M1
I have the AGPS UN-Checked

Thanks for the tip, I just updated to this radio from 1.02.25.28 and my GPS seems to be working much much better!
Hi,
I've got two apps on my kaiser: QuickGPS and QuickPosition and those two apps should be speeding up time for determining position by downloading file. I'm refreshing both files but there is no difference with or without this "apps" and my ppc is searching and locking GPS so long.
Can I set something in registry or somewhere? Or should I use only one of that apps (QuickGPS, Quick Position?) Where is the problem.
- Yes I Am trying to connect GPS under the sky -> outside.
So, what can I do to speed up that "locking"?
Thanks a lot.
(Its really stupid to walking outside for long time to get position...)
btw: Sorry for my bad english.

Getting a first lock can take a bit of time -- upwards of 10 to 15 minutes sometimes. There are a lot of variables -- your radio's sensitivity (how many satellites it can 'see'; whether there are clouds; the number of satellites available, signal strength; bounce off local buildings, etc.
First of all, know that the Kaiser's GPS receiver is not all that great, so A LOT will depend on the version of the radio firmware you have installed. I'm currently running 1.70.19.09 which seems to be pretty good for most of us on NA, but other parts of the world are seeing different results.
After each soft reset, the GPS unit will lose all knowledge of satellites, etc. This is supposed to be supplied by the QuickGPS applications, but I have rarely found them to be much help (as have you). In this case, the GPS is in what's called a 'Cold Start' state (no knowledge of where it has been), so it needs to download all the information about the satellites (the Almanac) from one or more of the satellites it can see. Since this is only sent in little bits with the main position information (used to track you), this can take up to 12 minutes even under ideal conditions. You'll see it has the almanac when you see a whole bunch of satellite #'s show up with no apparent signal strength.
Then, once it has the almanac, then it has to get signals from at least 4 satellites at a consistent strength for a set amount of time (depending upon the algorithm in the navigation software) in order to calculate a 'fix'.
The good news, is that after the first fix, as long as you don't soft reset the Kaiser, or move hundreds of miles before turning on the nav software again, the time to get a lock will be MUCH shorter.
So, bottom line -- be patient on the TTFF (Time to First Fix). It can take a while. Clear skies and visibility of 3 horizons is best. AND, take a look at the Ultimate Radio Thread. Lots of us are experimenting with different radios to find which one provides the quickest fixes in our locales.
Could it be WM 6.1 again?

Let me guess, you have Windows Mobile 6.1 on your device? Have you seen the *Hopeless* GPS after 6.1 update thread yet? If I guessed wrong, the combination I have (shown in my sig) works fine with GPS and other than Tomtom Navigator 6.032, the rest is all HTC default.
Is there any way to store the almanac on the ppc between resets?
I thought that's what QuickGPS is for. But I think I've found that you need the right combination of Rom and Radio to take advantage of QuickGPS.
Currently, I'm using:
rom: AthineOS Faster Than Everything on KAISER, the naked version
radio: 1.70.19.09
And the Time to first lock after a reset is about 30 - 45 seconds. I'll be sticking with this combo for a while.

Not that I'm aware of. QuickGPS downloads a 'generic' ephemeris dataset from the internet, but that's not the same as getting the actual, current almanac from the satellites themselves.
Have you guys tried using GPSTest to get that 1st lock? Using PDACorner v16 w/ 1.58.25.17 radio and usually get a lock within 30-40 secs, have problems without GPSTest...
On most ROMs I had, it was impossible to start IGO8 alone while AGPS was on. The PDA would simply freeze or never detect the GPS.
The workaround was simple however, you had to start the GPS with another software before (and staying in background).
Recently, I found this thread on Development And Hacking and I gave a try. This is a driver enhancement to fix lag. But as a side effect, it prevents IGO from freezing !
I can finally start Igo8 alone, it works great !
(results may vary depending on the ROM - I'm using TPC StockLike 23049)
yes, you are right. my igo8 now starts with a-gps on if i run VisualGPSce first. (i used advanced config to turn it off a-gps a while back)
but what does a-gps do? it was not any quicker fixing. or am i missing something?
on the page you linked, what exactly did you install? there cabs and registry fixes (sorry i am being lazy, there are 14 pages)
I've just installed the cab on the first post (v0.9) and voilà, no registry change needed (those are for fine tuning).
igo8 version?
Which igo8 version you used? I have been using a lot of different igo 8 versions and never had a problem not detecting the GPS. A-GPS asks me weeky to allow downloading the newest GPS data from internet, so I guess I am using A-GPS as well.
The GPS itself is not too quick though, my g/f's diamond locates our position every time way quicker. Will this cab you mentioned speed-up getting the fix?
I used PDA Corner ultimate x-v4 to date, just upgraded to x2-v11.
Altough QuickGPS is asking to download every now and then, that does not mean that AGPS is enabled. Most ROMs I have used (PDACorner's ROMs included) disable AGPS by default.
Any version of iGO I used would freeze with AGPS enabled, while they work with AGPS disabled.
From what I tested, the driver lag fix helps when moving slowly or not moving at all. It doesn't get a GPS fix faster. However, since it redirects GPS calls, iGO does not freeze.
AGPS can help getting fixes in a couple seconds. Diamond has no issue with iGO and AGPS.
Grrrr
Doet voor mij geen donder. Jammer
Didn't do the trick for me. Installed GPSMod 1.39 on Ultimate X-2 V11 ROM on a Tilt (TyTN II) and IGO still hangs on 'Starting'
This is using the default GPSMod Port Com1.
If someone does get this working on a TyTN II / Tilt, let me know
