GPS not working?? - XPERIA X1 General

I've tried built-in GPS without success.
Default GPS settings are:
- Common port: COM 4
- Hardware port: (None)
- Baudrate: 4800
- Windows Manage: Yes
I've tried many programs to test NMEA/SifR data but nothing works.
I'm unable to try with Google Maps because I've got any flat-rate so I don't want to loose 20 dollars for tests.
One program for "Find Port and Baudrate" (AutoDetectGPS.exe) has discovered something like "NMEA" on "COM 4 Baudrate 2400" but all programs (like Google Maps) doesn't accept that low baudrate (starts from 4800).
Something wrong?

The GPS on mine wasn't working on the standard Vodafone ROM and the R1 generic, it was only after an upgrade to R2A (and subsequent downgrade back to R1) that it has been working.

"subsequent downgrade back to R1"??? why that?
However mine is R1 but there isn't any upgrade to R2A jet for italian version...
Mine phone is not branded so I don't know if unbranded ROM is better then Vodafone's one.
grrrrrrr....I want to use GPS!!!

Not exactly sure how using Google Maps in a stationary position is going to cost $20. Even on some of the most expensive data tariffs I've seen you'll be unlucky to be billed more than $1.
Give it a chance. Go outside, boot Google Maps, in the menus tick "Use GPS" and watch the number of Sats increase in the top right corner (may take up to 5 minutes on first try).
Also give "Quick GPS" a go. Might help speed up the pinpointing.

In Italy there are FLAT-rates for xxx MB of traffic in internet for 20 euros or 0.5 euro for every 15minutes after each connection.
So to try GoogleMaps few times I need to spend many euros
For that reasons I'm trying with other software...I just need to see SAT-number and LAT/LON from a textual software, but all softwares cannot reach COM Port data-stream...

I think google maps may cause problems, (because of a-gps?)
I have the stock rom (r1) and gps works, but i need to "calibrate" it after each hard reset (stay somewhere without to move and wait for the fix...)

you could always sit next to your window and use wifi as data connection

Orange UK AGPS settings

I'm trying to get AGPS working on my blackstone and like other people have found if I turn AGPS on the GPS keeps dropping out.
I think this may be because of AGPS settings in the HTC ROM I'm using (HKCSL_WWE_1.19.831.0) having a non Internet routeable server address 10.1.101.63
[HKEY_LOCAL_MACHINE\Software\HTC\SUPL AGPS]
"ServerIP"="10.1.101.63"
I'd like to try it with working AGPS settings for Orange UK's AGPS server.
I think I know the server name is "agps.orange.co.uk" but I don't know the port number, has anyone got a phone with a standard Orange UK ROM and could check the settings for me?
The ones I need are:-
[HKEY_LOCAL_MACHINE\Software\HTC\SUPL AGPS]
"ServerPort"=
"ServerIP"=
"ServerURL"=
"GPSmode"=
Thanks a lot
Peter
Are you still looking for these settings?
I have a vanilla Touch HD ..
Let me know where to find the settings and I will give them to you.
Hi yes still looking for the settings.
To get them you'll need a mobile registry editor either on the phone or on your PC
Then the settinsg I need are in:-
HKEY_LOCAL_MACHINE
Software
HTC
SUPL AGPS
And the actual entries are (not all of them may exist):-
"ServerPort"=
"ServerIP"=
"ServerURL"=
"GPSmode"=
If you can get them for me many thanks
Hey there,
I'm on a standard Orange UK ROM. Mine is as follows:
"ServerPort"=7275
"ServerIP"=10.1.101.63
"ServerURL"= (not there!)
"GPSmode"=2
Hope it helps!
Ah right thanks.
That probably explains why AGPS doesn't work for most people if they enable it makes the GPS drop out.
The settings look like they're internal test ones used at HTC, the IP address 10.1.101.63 is the same as in a stock HTC ROM so can't point to Orange's agps server.
Thanks for checking for me, I'll have to carry on searching I think
Have you tried agps.orange.co.uk port 7275?
Hi, that does look better after a very quick test, TomTom isn't saying "No GPS device" every few seconds with AGPS enabled.
I'm indoors at the moment though, so I'll have to give it a proper test tomorrow when I'm out in the car
Thanks
No, just tried it in the car and it's still dropping out to "No GPS Device" with AGPS enabled, disable AGPS and it's OK again
Looks like AGPS just doesn't work properly
Thanks for all the help anyway
There are several threads where AGPS has been a problem.
A fix is achieved by the receiver, AGPS and QuickFix. In my view AGPS causes conflict where a low cell tower signal is present. Isn't AGPS achieved by a rough triangulation from cell towers?
Disable AGPS with HD Tweak and let upto date QuickFix data do its work just like it did on TTN6 on other devices without problems.
Get your first cold fix outdoors, stationary and with clear sky would be good. This may take a few minutes. Subsequent warm fixes will be much faster.
The HD receiver is not as sensitive as a SirfIII IMHO but it does work fine.
Yes, I agree AGPS just isn't working on the Blackstone, at least for me.
I've only just got the Blackstone to replace a Kaiser and I've noticed the GPS on the Blackstone gets a first fix a lot faster than the Kaiser used to.
On the down side though TomTom 7.910 on the Blackstone seems to suffer from much worse lag than TomTom 7.450 used to on the Kaiser, perhaps it's just that it's driving five times the screen area perhaps.
The "lag" for me is one second. Which is the refresh rate of TomTom Navigator. No significant difference from my Artemis with v6.
No not select too many POIS for display as this effects the redraw time.
Lag often 4-5 seconds here - Possibly all the speed camera POIs in London, where I live

I have just got it working on orange uk using the following
IP address: 194.51.71.162 - found by pinging agps.orange.co.uk
port: 7275 - looking around the forums, most mobile providers seem to use this port.
i deleted the serverURL key, and my gps mode is set to 2 or 4(this tells it to use cell location and the orange server)
With these settings, my tomtom software first (after about 20 secs) goes to the center of the local orange cell, showing five satellites which are actually the agps "pretend" ones. It then picks up the real satellites and my position moves to the correct gps position. I never had much issue with the position from the standard gps signal, but the altitude reading is now much more accurate, showing the agps is having some effect (no idea why I would need an altitude reading?!?)
Whilst the tomtom software works perfectly, my memory-map software crashes when it tries to load with agps turned on. If another program (ie tomtom) has already initalised the gps, then memory-map also works fine.

GPS settings for 1.56

Hi everyone
I have recently updated to 1.56.405.1 ROM which also included Radio update to 1.13.25.24. However, I have noticed that my GPS no longer works on this ROM. in google maps, it shows "Seeking GPS satellites(0)" forever.(Com4 port for internal and none for external devices) I tries changing baud rate to different settings - 9600, 57000 etc, but even if I press "ok" after setting baud rate, somehow, it comes back to its original to 4800. How this happens ???? its really frustrating. My earlier ROM (1.19.xx) used to show GPS position using Googe maps.
Can any1 guide me how to make things work here?? Also, can some1 please post ideal GPS settings?
I know this will not be helpful, but I'm using Miri wm6.5 v9.2 which my gps locks on within 30 secs on TomTom, Memory-Map and Garmin. Google maps locks in quickly. I used the default settings (com 4) and all works fine.
The ideal GPS settings are default settings
Program port: COM4
Hardware port: none
Baud rate: 4800
Manage GPS automatically: checked
Any other settings of GPS you should set from GPS application.
Thanks guys...I'll try these and reply you back here. Please do read this thread after a couple of days.
default setting is baudrate:9600 isn't it?
No, read above, please
Can you actually change the baud rate? It reverts back to 4800 when you re-enter the settings, so I can't change it at all.
To,
the person above this post
same here dude !! earlier I could change in 1.19XX rom. but ever since I have flashed to 1.56, i'm facin this problem you've mentioned.
BTW, do you get GPS application working properly or same like mine?? [pls. read 1st post in this thread]
Regards
Ash
If you read up in the internet, you can read everywhere that the default value for the baudrate is 9600, so that the internal GPS receiver is demanded best of all in navigation software.
And you say it would be in 4800 now?
i have the same new stock rom and i have four working gps programs which all also lock to satellites within thirty seconds without ever seeing the settings yet along changing them :S are you guys sure this problem is not self inflected .. i wish i could help but i have no idea how..
the applications i use are route99, garmin, navNgo and another one which i forgot since i dont use that often.

Not true.... i have done a lot of reading into this on various forums and settings can depend on radio's, roms, devices and software used. Also i am using 1.56 wwe and my default settings are 4800, com4, none hardware port, windows manage and my gps works fine, cold start about 20 secs, warm start up about 5 secs depending on location and weather conditions!
Conclusion, well i dont have one yet, i am trying to compile a list of typical settings device specific but it is fairly obvious that there are a lots various circumstances

What I've noticed on 1.56.401.0 WWE ROM is that GPS fix with Garmin Mobile XT is much faster, but the icon on Garmin "home" screen shows as no signal. I can navigate as before, maybe even better, just this funny thing with signal indicator... Any1 else with this issue?

Most PDA GPS's do not turn on automatically by themselves unless instructed or invoked by a software application. I have not looked carefully at my Jade clone's SIRF's specifications but most GPS under ideal situations can take as little as 42 seconds when warmed up to get four satellites to lock on to. Four satellites are necessary in most sytems are necessary for 3D satellite navigation (satnav or GPS).
What are ideal situations? Glad you asked. Basically, one of the most critical needs for a GPS is accurate time. This is the first item that must be sync'ed by satellites. To use a gross example, let's say your clock is off 60 minutes. In a car that could equate to roughly 60 miles. Satellites need accurate time because when they begin to sync, they will compute what satellites are available to sync with your GPS. Just like the sun, moon and stars are only in the sky at moving intervals of time, only a fixed amount of satellites are overhead at any given time.
Once your GPS begins to sync, ephemeris data (which satellites and the times they are overhead) is transmitted to your GPS. When combined with accurate time, the resolution of where your receiving GPS becomes easier.
The next critical issue is where does your GPS think it is. If the GPS was last turned on at the factory (testing), then it will store that location as its last known position. Guess what? If you're in Paris, France and your GPS was made in Malaysia, your last known position known now as initial positon to the satellites will tell them based upon time to use satellites in the Asian area to compute your satnav position. A GPS without a good initial position will make it difficult for satellites to accurately determine your location which could now takes a minimum of four minutes as long as ten minutes and maybe even hours.
Finally, where is your GPS physically located? In ideal conditions, it is outside with clear sky overhead in a stationary location. It's easier to shoot a sitting duck; a moving target or a GPS on the go complicates all the issues of time, location and signal acquisiton.
To help you, I recommend you download a small cab file that be used in your Today screen. It is aptly called "GPS Toggle". In essence, like a mechanic warming up your car prior to you driving it on a cold day, this plug-in "warms up" your GPS for you prior to needing it.
There is one thing you need to do to help your GPS - it is best for WM to manage it (a recommended feature from Microsoft). Go to the Settings tab, External GPS (why it is called that on my Settings tab is beyond me). Then click through the screens to have WM manage the GPS. On one tab you will asked to choose a Port from which all your programs will access data. You need to use an unused Port. I recommend Port 9 but that is up to you.
The reason for doing this is if WM manages the data, it will keep the GPS on and provide the resolved info to all applications. If the programs managed the GPS, they could selectively turn on and off the GPS and also block each other from using the GPS. You don't want that to happen. That is why MS recommends WM manage the data.
GPS toggle, when installed on your Today screen, will have an ON/OFF switch. When you turn it on, it will on the same line tell you how many satellites it has found and when it has sync'ed with them. When you see that four satellites are in the green (meaning your GPS is found ready for 3D satnav), then you can use satnav program of your choice.
The GPS uses battery power and supposedly is a big drain on smartphones. You want to turn it off and on only as necessary. Hope this helps (it's sticky stuff good info)!

Open the Settings tab, go to "System" and look for "Device information". The CPU must be Qualcomm MSM 7225 and the full model name should be Touch 3G T3232. If not, it's a fake.

Cloned HTC Touch 3G
I went through the posts - I guess even I have landed up with a cloned HTC Touch 3G. Wonder what the drawbacks are. Somehow after a lot of tinkering I have been able to get my GPS to work (yes it has a built in GPS antenna) and it's accurate!
I set the hardware to COM 3, baud rate 4800
application to COM 0
In Google maps>options>GPS settings>manual settings (COM0 baud rate 4800)
IT WORKED!!
The WiFi can't be turned on with TouchFlo. Anybody has a solution to that?

GPS and other settings

I have a blackstone and it was originally on the Orange network (UK) I now have it unlocked from orange and have a T-mobile uk sim in there.
I put tomtom sat nav on and havent done much else to it.
For some reason I cant use the tomtom app as it says no gps device, any idea whats going on, or how I fix this. I follew the tom tom installation correctly but it just doesnt pick up any satellites up.
Another thing is my MMS setting are out of wack completely, any idea how I get these fixed, t mobile are unable to help as they dont sell the phone through them.
Anyone got their mms worksing through t mobile uk?
any help would be appreciated
Yes..you have find a big bug in the new rom that you have installed...i think that you have burn the GPS antenna, or the second possibility is that you have to install a new Antenna software..i've a original rom and all is perfect.!!
i havent installed another rom, its the original one that was on the phone, so i couldnt have burnt anything out. i haveng modded the phone in any way just to confirm
I'd try this for the MMS settings:
Tmobile Settings by Email
For the TomTom problem, it is just a case of TomTom not displaying any Satellites, but still getting your location (the screen changes colour and shows your location, to indicate a satellite lock) or does it never give a fix.
Not to insult as I don't know your level of experience with GPS, but try it outside on a clear (not very heavy cloud) day, leaving it stationary for several (upto five I'd say) minutes, and see if it gets a fix?
thansk for the reply,
but the t-mobile link odesnt work as my phone isnt listed there and I cant move forward without selecting one.
The tom tom screen is grey as if it doesnt have any satellites connected to it, I have tried it on a clear day and same no luck.
In the connections tab under where you can switch the bluetooth, wifi etc on, does the data connection also have to be switched on, of is the data connection for something else?
For tomtom:
Go to settings/AGPS settings and make sure it is turned off - this used to stop tomtom working for me until I updated my ROM.
In tomtom, make sure you've selected 'Other NMEA GPS receiver' and COM4 (I found the baud rate does not matter and have it set to the highest value.
thanks all working now, great.
just on a general note, what costs are incurred when we use this, is it free for people with data plans etc

GPS does not cost anything as you are receiving signals from GPS satellites. I don't think you even need a SIM in your phone to use it.
AGPS is data so will come out of your data plan if you have one.

Optimal GPS settings for faster GPS lock on HD2? (Also using GarminXT)

Hi all,
I didnt want to start a new thread, but after searching the forums and google for a long time, i decided to bring it up
So ive had my HD2 for about 2 days now, and I recently installed GarminXT (I used to have it on my Nokia N82)
the problem i'm finding is that the GPS doesnt lock as fast as i thought it would be..
GarminXT has not been locking on (little over 5 minutes now)
I'm a noob to Windows Mobile and HTC so please bear with me!
1. How do i know A-GPS is working? Is it automatically enabled? (This wasnt the case for Nokia as you could manually turn off A-GPS and use strictly GPS signal). Under Location settings i have "Location Service Settings" = ON
and HTC Location Service = ON
2. Im still not 100% sure what QuickGPS does. I've read about it , but all i concluded was that it uses your data to get a faster GPS lock.
So i tried running QuickGPS and it updates no problem.
I open GarminXT and it doesnt lock on. Do i need to use this?
3. Can someone tell me if these are the optimal GPS settings? I kept searching around the forum but cant find one specific to the HD2.
So under "All Settings" > System > External GPS
Programs Tab > GPS Program Port = COM4
Hardware Tab > GPS Hardware Port = None > Baud rate = 4800
Access Tab > Managa GPS Auto = Checked
Are these settings correct? Or are there "tweaks" to it that I can change?
4. One last question:
Under GarminXT, i have the ability to choose 3 GPS options:
"Use Bluetooth GPS"
"Use GPS Intermediate Driver" = Checked
"Use Serial GPS" > Once selected, i get 4 other options to choose:
COM1: Bluetooth Serial Port
COM2: Bluetooth Serial Port
COM4: COM4:
COM9: 7500 COM port
Does anyone know if i should be checked on "Use GPS Intermediate Driver" or if i should be checking off "Serial GPS" > COM 4?
This is my first WinMo device with a data plan (I'm on EDGE speeds cause I'm in Canada), but I always had the impression AGPS would really help the lock times.
Anyone with help would be GREATLY appreciated!
Again, loving the new HD2
Thanks
For GarminXT, use intermediate driver.
For Google maps, use Com4, 4800 rate, that enables use of the compass.
Quick GPS should increase startup, and so far I had all fixes on HD2 under 30 seconds, and I did not change anything.
Normally GPS would download information about orbits of satellites from the satellites. That can take time, as it is one way communication and GPS can't ask satellite to send data again in case of error, it must wait untill the satellite starts sending them again by itself.
It is much faster to get that data via network .. and that is exactly what QuickGPS is for. Problem is that at least on my previous X1 there were many problems with it. The data from network was sometimes completely wrong, and you had to delete the file manually. That information is in temp\xtra.bin. Try to delete it and try again. QuickGPS does not test existence of the file, it will download new one in predefined time.
I'm still a bit confused about aGPS. I'm not sure what it is. Some people state it is the same thing as QuickGPS. Some say it is something to get quick basic fix based on BTS. But I haven't seen that in any application, except Google maps, and they seem to use their own technology and data for that.
But AFAIK, those 'location services' is generally Google's 'my location' exposed for other HTC applications.
I set it on max rate, do i do a mistake? I think that this is setting the speed or Im wrong?! Im connecting with sattelites below 15sec, with no other tweaks or quickgps...
^^
what's "max rate"?
btw, thanks for the replies
i'll look into deleting the cache file for QuickGPS and see if it does anything
Quick GPS allows you to download a weeks worth of GPS satellite position data (almanac data) at one time, helpful if for example you don't have a data plan - you can get your A-GPS data in one hit over WiFi. It helps speed lock time.
Not sure what is happening with yours, mine always locks in Garmin within 7-15 seconds, I have Quick GPS set to autoupdate, but otherwise no special tweaks or modifications where GPS is concerned.
Same here - in fact, the HD2's locking faster to GPS than my Touch HD ever did. I'm getting locks in the garage now whereas before I had none with my Touch HD. Haven't touched the default WM GPS settings or the Garmin one at all since I upgraded to the HD2.
GPs lover-Google map hater
Hi guys, firstly thanks for this thread as i too look for answer...and find some only here
i had the Diamond and now the HD2 and share the love.
Garmin maps are much more accurate and have even the smallest unpaved roads which Google map lacks. Google is so basic maps, i simply hate it...sorry Google...not to mention that it cost money to be online all the time
HD2 GPS confuse me. Sorry if I ask u basic staff but could not figure it up myself:
1. using the GPS w/google map, how u set simple setting, as: "north up" or ""track up" Route setting such as "faster time" or any other basic settings that I always had on my Garmin GPS including Garmin mobile XT?
2. What happend to voice navigation wiith google?
3. Reading your info, does it means that I can install Garmin mobile XT I got with Diamond on HD2 ?
4. Anybody know TomTom for HD2 (which I will get shotly from HTC?
I trust someone out here is smarter than me and will come to rescue
hey guys,
my HD2 is fine now, usually i just do a QuickGPS connect before opening Garmin XT and now it connects SUPER fast...usually under 10 seconds
Thanks for all the help!!
Google is not, and does not set out to be a full satellite navigation prpgram, so it doesn't have stuff such as 'North Up', 'Track Up' etc, nor does it have spoken directions.
For these you need a dedicated SatNav program like Garmin, TomTom, CoPilot or iGO8 which are all 'paid-for' applications.
TomTom will run fine but TomTom don't officially support it, meaning you can't download the correct vesion direct from their website. There are easy ways around this though!
With regard to some of the earlier posts- the HD2 can aquire a fix faster than any other device I've used (and I've used a lot!). I find QuickGPS makes very little difference, but as it uses only a small amaount of data I keep it updated.
QuickGPS and A-GPS are not the same thing, though there are quite a few different definitions of A-GPS. Genuine A-GPS is not used in UK, nor as far as I know anywhere else in Europe except by dedicated programs and platforms set up with the infrastructure (such as Apple, who use it to enhance the poor performance of the iPhone's GPS chip). It is used in the Far East, and works by enhancing your accuracy of positioning by using the data channels to send your current cell ID plus any other availble stuff like WiFi hotspot info, which is correlated to a database of locations, and sent back as an approximate position to the phone. Google Maps uses something like this if a GPS signal is not available- the 'Locate Me' feature will show you in a radius of around 1km.
The Baud rate makes no ostensible difference to the lock times or accuracy, as the data stream from the satellites is far lower than even the lowest baud rate. The NMEA default is 4800, and most software is happy to connect at that rate.
The google maps GPS finds me within 80 metres.. that's not accurate right? cause it puts it on wrong street technically.. When I first got it it did 800 metres =/
WOW, that was fast, thank you NeilM.
I will get Tomtom for free from HTC as it is included with Thai purchaded HD2.
Meanwhile I will try to load Garmin XT that I got with My Diamond at the time, let's see if the activation works...
As for Goole, well, I get 60 meter accuracy at the best, that make ones totaly lost in a city and for sure miss a turn, what a pity.
Thanks again for ever so fast reply.
When Google Maps is started it is finding your position throught the carrier's network and that is why it is not acurate at all. There is an option however, named "Use the GPS" in goolge maps and it becomes as acurate as any other navigation software It just have to engage an GPS lock as the others so do not blame google on this one Hence, you are not using the GPS when you get the inacurate positioning For the maps however you still have to be online But if you pay for your Garmin, iGo maps it would be that expensive and you can use it wherever you are ...
You absolutly right. i did use the "use gps" and it's accurate. The thing is that as heavy GPS user the lack of detailed info on google maps, and the inability to set the maps at your convinient (such as "track up" for example) it's nearly a secure way to go crazy while nevigating, specially off road...try to tilt your head to understand your position in real time when you turning and turning. Thanks for the gps tip.
I agree. Curent version of Google Maps is not suitable for navigation while driving indeed! It can help you get orientated sometimes or if you are looking for something big iGo and Garmin are in a whole new league of navigation sofware for now. However, the new version of Google Maps should be at least as good as the others but it is only available for Android at the moment and I dont see it coming to WM any time soon so we will have to stick to iGo, Garmin, TomTom and the others. I'm not using Google Maps for navigation at all by the way so It wouldn't be so difficult for me )

It's called google navigation, not google maps - and it seems to kill every GPS program available today (thank god).
hey guys,
on the same topic, but different nav software. i use iGO 8, can someone please tell me what the optimal setting are for port and baud rate? i did the auto-detect and the signal is a little on/off.
also... is there a way to get iGO 8 to use the HD2s compass? i like the stand-alone compass of the HD2, but i think it would be swell to be able to have iGO's compass function working aswell.
sorry if this has been discussed before, if there is another thread i should be reading... please direct me there.
thanks for all your help.
cheers.

Eh, if I'm not wrong, that's agps at work.
It'll find you with the nearest base station. then slowly try to triangulate you. Normally, you'll be in an area with only 1 base station, so there's not much triangulation going on.
When I'm in city, it's pretty accurate. I get my approx distance within a couple of seconds, wait another 10 - 20 secs to get gps fix.
A-Gps and other things
A-GPS is just one thing: Assisted GPS. It is a toggle-- when you toggle it on, in your phone's settings, you will get the locational assistance of the cell towers. That is the towers them selves, two or more towers and your phone triangulate to give an approximation of your location. GPS also uses triangulation (derived from simple trigonometry equations) to determine your location and is much more accurate. In fact it can be ever more accurate as your device locks onto more satellites. I have found that the best thing to do is to turn off A-GPS. I don't know what it is but Googlemaps seems to have a terrible time locking onto satellites on Windows Mobile. But I have found, especially on Android 1.6 and above you get very rapid locks so long as you wipe out the telenav program. I strongly suspect that Google is undermining Windows Mobile in favor of supporting their Android system. They have turn by turn for Android but not for Windows Mobile and it seems like they are also building it not to lock sats nearly as well. You can force it to get moving by pre opening the GPS or other methods just prior to running google maps.
I think everyone should write google and tell them to fully support Windows Mobile (Phone)... T-Mobile is just about set to come out with the HTC HD2 in about a week (March 24th) and I intend to get one. I am not happy that it doesn't have a physical keyboard cloned from the Touch Pro 2, but I expect to like most of the rest of it.
Turning Location on is another thing. You are henceforth allowing all applications to know and your location. this can be helpful but it can also be a potential privacy risk. Of course it's easy to turn off and on. You might want to read the fine print.
Actually, I have a more basic question. Is there a soft "switch" or software application to actually turn the GPS on? On my HD2 I have a few GPS apps and all of them report the GPS being on or "no GPS Device found". Even Goggle maps, if I siwtch to USE GPS mode, keeps endlessly waiting for a GPS signal and then nothing happens. What am I doing wrong?
Thanks much
Gps htc hd2
In my experience with windows mobiles and internal gps, manage gps automatically is best and no ports should be assigned at all unless using bluetooth gps receiver! Also, sounds crazy too many but no every location on this big earth is withing available to public gps devices gps satelite paths (satelites going around the earth!) Make sure your outside the house or flat before thinking your gps ain't picking up. My hd2 is fast, my old mda3 was too and worked better inside but thats down to i was living in a different location at the time and at an higher altitude i would say. 1 of many other reasons could be that the military could be using the sat at the time which would render it unavail to public (offline)!
