GPS signal only in my city/area? NEVER abroad - Touch Diamond, MDA Compact IV General

Dear All,
I've a strange problem (I have TT6 and IGO8 on my Diamond + FULL EUROPE maps):
*in my city/area (Milan-Italy) the GPS signal is fast and perfect and the navigation is totally ok.
*When I move to other regions or nations (e.g. to Rome which is 500km from me, but I've tried also abroad, in Belgium, Holland, Denmark, Romania, etc.) I never get enough satellites, I never get GPS signal. I mean NEVER. I waited for minimum 30 mins each time, and no signal.
It sounds very strange to me, are there any settings to change?
PS: I always download the GPS ephemeris when I'm in my city, before to travel. Do you think this is the problem? Should I download the GPS ephemeris every time I am in a new location to make it work?
Thank you

Downloading the ephemeris data for where you actually are should help speed things up, but you should still get a lock after a while.
Last month I flew from UK to South Africa. Switched TT on in the taxi from the airport, changed to Southern Africa maps and within 5 or 10 minutes I had a lock and the map was showing me where I was.
Cannot understand why this is not working for you though

Thank you, I think I'll hard reset again, and I'll install only the navigation softwares to see if there are other applications causing this problem, otherwise I'll bring the device on warranty repairing.
Many thanks

a-gps?

GPS not working suddenly!

Help! Only had this a couple of weeks and it's starting to drive me nuts. When I first got it, Google Maps had no trouble finding satellites but now it comes up with 'No GPS receiver was found' screen over and over. I did switch QuickGPS off for a bit and I think it's since then it's not worked right. Does anyone have any idea what I can do? It's a UK branded Orange TytnII (Kaiser).
*I really want to start messing about with ROMs too but have a Mac and don't think there's a way I can is there?
Have you tried going outside? Line of sight sometimes will work!
Yes I have, hasn't worked. It wasn't working when I was walking round London yesterday but I assumed the tall buildings were causing the problem but now I'm in exactly the same place I was when I first got the phone and then it was was picking up 4/5 satellites. Now it's just coming up with a screen telling me I have no GPS receiver. Could the receiver in the phone have been damaged? I haven't dropped it or anything and have been pretty careful with it.
Reinstalled Google Maps. Now seems to be working. Grrr. Sorry to have bothered everyone.
Read this thread for a possible fix; http://forum.xda-developers.com/showthread.php?t=333275
You probably need to run quick GPS and get the download.
I have this set automatically now and it usually downloads weekly. I often wonder what I'd do if I needed the GPS somewhere where there was no phone signal to download the updates!
Hi, I had the same problem, and all apps GPS don't work !
Hard reset no change the problem.
I sent htc support, Finally they changed the motherboard !

Tomtom 7 - Poor GPS reception, are you in a building?

I have had trouble with the GPS on my device ever since I received it.
The start-up time is very slow 5-10 minutes standing in the garden.
In the car I very rarely get a lock at all
Once I finally get a lock the signal is poor and drops out easily.
When I restart a GPS app (even 10 minutes after closing) it seems to take the same amount of time to re-start as though it is starting from cold again.
I've tried Google Maps, TT6 and the HTC GPS tool, several different ROM versions, aGPS on and off, Quick GPS on and off. None of which seem to make any difference.
Yesterday I decided to give TT7 a try and had the same problem getting a signal but also had the following message on the GPS screen 'Poor GPS reception, are you in a building?' I'm now convinced this is a hardware issue as my previous touch diamond (HK version returned due to a faulty speaker) picked up the signal quickly and was very reliable. I have spoken to the Expansys about this, but they have said that if I can get a signal at all then it is not a hardware problem and must be software related.
Is anyone else having similar problems or getting the same message in TT7
More importantly any one managed to find a fix for this?
If TomTom has a weak signal, then "Are you in a building" is a standard message TT7 is giving. Whether you're in a building, a basement or metal encapsulation.... it will give you that message Mine takes about 15 - 30 seconds to get a fix, with TT7 when I use it for the first time after my phone has booted.
I still get this message if i'm standing in the middle of my garden. The performance you are getting is similar to what I had on my first device, Which was one of the Hong Kong devices from Expansys. The replacment which I am now using is a European version. can I ask which version of the phone you are using.

What ROM version do you have?
My HK one had issues with the shipped 1.34 ROM but is fine now...
Have you changed any of the default settings for GPS?
I have not changed any settings and my TT works fine.

Mine is European too, Dutch to be specific.
It's running rom 1.37.404.3.
Same problem in my samsung omnia
I'm using 7.450 build 9080 I'm sure it's a tomtom issue cos pocket street can fix the gps position, but tomtom keep me saying poor gps reception.
I have setted the gps to com7 and hardware com9 4800, I have also disabled the enhanced gps.
Ay help please or if someone knows how to disabled the internal gps so I can use my external gps receiver.
Regards,
Hlov
i noticed the although it might look a long time for tomtom to get a fix, just enter your destination anyway and it seems fix goes hell of a lot faster!

I have the same problem. Can't figure it out. My signal i sporadig. Specially when you go to settings....show gps status. I can see hoe the gps gets contact for a cpuple of seconds and then disconnect. And it does this over and over again. I can se my position, but the map never gets in colour....strange...
Have you tried updating quickgps? I find that unless the quickgps data is valid, tomtom can't find any satellites.

[Info/tutorial] How to manually configure a-gps server

Hi there,
This topic is about my experience of configuring a-gps manually with a French operator. This may help others.
I installed a few day ago the last french official HTC ROM (see here)
My Diamond is SFR branded (French Vodafone), and after upgrading from the native SFR ROM to the HTC one, I felt a slowdown to get a good GPS signal for the apps I use: Googlemaps and iGo8. The signal also seemed less accurate.
I decided to investigate this way.
First of all, some elements that may be obvious for most of you, but reminding them does not hurt:
A-gps is a system that enhances GPS performance, by connecting to an a-gps server. As a matter of fact, this server makes use of cellular network signal to locate you faster. For further informations, see Wikipedia a-gps article.
AFAIK, a-gps is different from Quick GPS (see here) In particular, config values for a-gps and Quick GPS are located in different registry keys on Diamond.
Now let's get deeper into a-gps:
You can, once again AFAIK (and you'll correct me if I'm wrong ), use two kinds of a-gps server:
Your mobile vendor's server (i.e. HTC)
Your operator's server
I remembered that on some phones (at least Nokia N95), you have to define manually your a-gps server when using SFR network.
For Nokia, the problem is that the port used by the vendor's server is blocked by SFR WAP connection.
This is not the case of HTC a-gps server, since using HTC rom does not inhibit a-gps: it only seemed slower to me than with my SFR rom.
Here are the registry parameters for a-gps, on the original HTC ROM:
Code:
[HKEY_LOCAL_MACHINE\Software\HTC\SUPL AGPS]
"EnableAGPS"=dword:00000001
"ServerPort"=dword:00001C6B
"ServerIP"="10.1.101.63"
"QosPerformance"=dword:00000059
"QoSAccuracy"=dword:00000032
"TimeBetweenFixes"=dword:00000001
"NumberFixes"=dword:3B9AC9FF
"GPSMode"=dword:00000002
I guess "10.1.101.63" is the IP address of an HTC's a-gps server (?!)
I then downgraded to native SFR ROM, and here was the same key:
Code:
[HKEY_LOCAL_MACHINE\Software\HTC\SUPL AGPS]
"ServerURL"="geoloc2.sfr.fr"
"GPRSConnection"="WAP SFR GPRS"
"Network"="WAP SFR GPRS"
"EnableAGPS"=dword:00000001
"EnabledPrivacyMethod"=dword:00000000
"CloseConfirmMsgTime"=dword:0000003C
"PrivacyMethod"=dword:00000000
"EnableLocInfo"=dword:00000001
"ServerPort"=dword:00001C6B
"QosPerformance"=dword:00000059
"QoSAccuracy"=dword:00000032
"TimeBetweenFixes"=dword:00000001
"NumberFixes"=dword:3B9AC9FF
"GPSMode"=dword:00000002
As you see, the server is defined with its URL, "geoloc2.sfr.fr" (known as one of SFR's a-gps servers), and some parameters are different.
Of course, you have to replace "WAP SFR GPRS" by the network connection you want to use.
I upgraded to HTC ROM again, and set the operator's rom values.
Now I've got the feeling that it's harder, better, faster, stronger (and more accurate).
By the way, QuickGPS is configured in the following key: [HKEY_LOCAL_MACHINE\Software\HTC\QuickGPS].
Note that, on SFR branded rom, this key does not even exist.
Hope this helps.
I've wondered why Quick GPS seems to replace the A-GPS feature on the diamond. QuickGPS doesn't seem to do a damn thing for me. From cold boot, I can stand in open air for 5 minutes until I even start to get a peek at a couple of satellites. How can we be sure that QuickGPS is even working at all?
I used to own a Nokia N95 that had the A-GPS feature, the GPS inside the N95 was pretty average. But with the A-GPS feature you could at least get a lock in under 10 seconds, every time. As long as you had configured your positioning server, (supl.nokia.com) and you had a data connection, then it was consistently under 10 seconds from cold boot. Without A-GPS it was more like 5 minutes plus, basically what I'm seeing on the diamond.
As people have noticed, using tools like Advanced Config to enable A-GPS breaks the GPS completely. Probably because of the missing settings such as you have outlined above, (I noticed these settings while poking around in the registry recently too). I wonder how we can find out what the server names for other countries are and get this working for eveyone.
Also, the IP address 10.1.101.63 is a private IP address so I guess that explains why it fails when you switch AGPS on, that address will never be contactable, so they must have used it for some kind of internal testing - but if it's working for you (with your new settings) then why did HTC choose to leave it broken for the other ROMS....
Well... Since I updated to this last HTC rom, QuickGPS "does work". I mean, it is an installed program, therefore available in "programs" list, and when I launch it, I can "download" data to update it. Though I don't have a cue of what use is made of this technology on Diamond.
I've always used Advanced Config to enable A-GPS, and it has always worked for me. But if it breaks the GPS, I guess you can do it from the registry by setting "EnableAGPS" value to 1.
I also tested a N95 8Go recently, and I had the same results.
But I'm not sure to understand your need: Diamond has both A-GPS and QuickGPS. I don't think QuickGPS is very efficient, but A-GPS is.
I do also think that setting the "ServerIP" value to "10.1.101.63" must work worldwide, since I bet this is HTC's a-gps server.
With this, GPS signal takes about 30 seconds to lock (at first use after soft-reseting, but may be under 10 seconds for next uses).
Did you give it a try?

Yes I have i too, and it connects and downloads data ok. But does it speed up a GPS lock? I don't think it does. I've hard reset and just run TomTom without QuickGPS and then with QuickGPS and I cannot for the life if me see any difference at all. In TomTom Satellite screen, you can see no data. If it was working, you should see all Satellite 'numbers' in their respective little boxes and then the tracking would begin almost immediately. But I'm not seeing this.

Many people have said that enabling A-GPS (via advanced config or direct reg edit) makes the GPS stop working completely i.e. never getting a lock. If you have got this working for you, as far as I know, you're one of the first! Lucky you!

No that IP address is within a private non-routable range for internal private networks and cannot be reached from the internet. Read this if you want more info.
I do agree though on the A-GPS being better, and with my experience with Nokia phones A-GPS is excellent. I don't understand what it is that QuickGPS is trying to do, because there is nothing quick about it. I thought it would be similar to A-GPS (in how it actually works) but now I'm confused :/

Now that's the sort of time we all should expect when using an assisted/quick GPS aid to the actual GPS chip. It should be lightning fast. So to me it says QuickGPS is pretty lame, as everyone is using it by default in all ROMS and there are many many people complaining about the GPS not getting a lock at all. So it can't possibly be working properly. And if it is, it still sux.
I'm going to try and replicate those settings you have above on my Diamond and see how it goes. I'll post back shortly.
OK well I've put all those settings in, but still no luck. It is not working. I've been waiting several minutes and still cant even get a fix.
It's not out of the realms of possibility that SFR's A-GPS server can only be used by SFR customers. After all, they assign you your IP address when you connect to the web on your diamond so they could easily lock it down so that random people cannot use it. In fact that would make a lot of sense.
I think we're close, but I guess we need to find a SUPL A-GPS server that is open to the public, maybe? Or certainly at least find out if HTC has one that we can use that is accessible via the internet... Maybe someone else has some ideas?
you can try: "supl.nokia.com" instead of "geoloc2.sfr.fr"
Have you tried this, and what port does it use?
I'd been playing some more and found out having it enabled really screws things up - TomTom thinks it has a lock, then it doesn't, then it does, then it doesn't, etc. It's really bugging out. So I just switched it off.
I'm really interested to know though if A-GPS will help with the ongoing GPS-Lag/inaccuracies problem, some poeple have reported that the lag is fixed in the new OS builds floating around but I can confirm that it is not fixed - in fact it felt like it was worse!
This GPS is causing too many headaches!!!

I'm also in Australia and i'm having the exact issues as you in regards to GPS lag and inaccuracies, i do however get a fix quite quickly, first time after a ROM change it takes a while but after that its somewhere between 30 sec and 1 min 30. I have changed my rom many times updating to all the latest custom ROM's, still its inaccuracy remains, its about 40 metres off on my device. I live inhouse number 16 and yet it tells me I'm at house 20. Like WTF........
What a pain in the arse!!!!
I got ip adress of HTC aGPS server!
its the 64.14.59.165
you got to just change the htc stock server of the diamond to this and its working well for me.

Tell me about it. Mine is about 50m off 90% of the time, sometimes it looks like it might be ok. The other thing I noticed today is that the 'speedo' in TomTom i.e. the bit on the status bar that tells you how fast you're going - which is usually very accurate - still tells me I'm going 15km/h, then slowly counts down to zero anything up to 20 seconds after reaching a complete stop! I am starting to regret spending money on TomTom. But to quantify that, I don't blame THEM, I'm just pissed I've shelled out so much for the Diamond + TomTom and the fkng things dont work properly. We have to get to the bottom of this!

Yep, its all the same issues I'm having, but not just with tomtom, I'm using iGo8 and garmin XT with no success.
This was written by me on another thread complaining about the GPS.
I called HTC support Australia and informed them off its fault with GPS lag and its accuracy, I informed them that over 50% of users are having this issue on the XDA forum, they told me that no fault has been logged and there isn't an issue, It may be time to call up the tech support and make some noise to get this issue resolved. its a pain in the arse and it shouldn't be happening.
I also called up Hong Kong Customer support the other day and they said the exact same thing...... i think.... the chicks English was just deplorable.
I think i may call the Australian HTC support again, and just irritate the **** out of them, hopefully this time they may have a solution for me.

It should be only a few KB send, and then a little more KB received.
It should only happen when the GPS is activated (e.g. you start TomTom) and then the A-GPS would kick in then. It should not transfer any more data unless you lost the GPS signal, then it would assist the GPS in getting a lock again, and therefore transfer another few KB.

xperia X1 freeze when use GPS

Xperia X1 freeze. After 6 months I have problem with my xperia and gps. When I try to use internal GPS (whenever software), display freeze and I have to replace batery. I have tryied to flash another ROM, it works few hours and now I have same problem. Any ideas?
Hi,ok let´s see, like you ive had the same problem, just when i was using any gps navigator the phone suddendly stopped and that was sucking me a lot so after that i started to think what could be the problem, and at the end after a lot of time i found where was the problem and what was the solution. To find the solution i decided to hard reset the new rom with which all my gps problems started, and following the instalation steps of all programs and configurations i found the problem and this was related with the quick gps, before using this program to upgrade my gps location my mobile was runing tomtom and others without freezing, but after upgrade the gps location with the quick gps my mobile started to freeze. So this is the problem, just do this try to hard-reset and install eveything but dont, i repeat dont !!use the quick gps or this will freeze your phone again. Following this step your phone will run the gps navigators without the freeze problem
Then men after this try to do this and let me know (PLEAE) if your problem still remain ok? see u and hope you can solve this problem like me.
I too have just started having GPS problems as listed above!
The problem seems to be Quickgps...as soon as u run the quickgps update(which you may have on autodownload) Tomtom crashes and you have to reboot the phone...
I have reinstalled a different rom since and still have the same problem!
i dont know if there is a cache for this program that can be cleared or something other than reflashing the device
As the days go on and the 7 day update starts running out im guessing more people will start having the same problems!mine happened 28/10/09 evening time!
Same problem: freezing XPERIA when using GPS!
Yesterday I connected my X1 to the PC and got the latest Quick GPS update. Today I'll need to use my gps for a trip... Wanted to prepare the navigator and got the same problem like you guys.
Probably something wrong with the last update since I have not installed anything nor updated the firmware.
Is there any way to get any older version of the quick gps? Before after each 7 days period, it was possible still to use the GPS. Even though it was much slower but in the end it always works before updating... Will a hard reset give me an old version of Quick GPS?
This is so annoying at this moment. Hope somebody find a solution fast.
Hi all,
Got the very same problem yesterday.
I tought the GPS HW had gone. I have uninstalled the Route 66 SW, but there are some files that still lay in the phone.
Then re-install everything from scracth, but problem remains. Now i know i a GPS. Could be worse if was a HW problem in the phone.
Possible solution
Hi
I have maybe same problem with other phone (HTC Rose). If any application try to connect to GPS, phone freezes. After Hard Reset it was OK, but only until I use QuickGPS. Then it again freeze whole mobile after use GPS application.
My temporary solution:
1.
Erase QuickGPS data. Simply delete 2 files: Temp\xtra.bin and Windows\xtra.bin
2.
Soft Reset phone.
Try it, and let me know.
working so far...
Thank you motaba.
I did what you proposed and erased the files. It worked actually.
I have been running my gps now for some minutes and it did not freeze. It found the signal and started to navigate without freezing.
So at first glance it seems to work. I will try it further and tell you all about further information.
but how can the gps work so fast and well without these quickgps files? are they totally redundant?
Greetings
Thanks a lot motaba.
Works for me as well.
As yes, it got the location pretty fast without the "A GPS mambojambo"
I was gettin 8-9 statelites.
P.S: Anyone can tell me were to get TomTom 7 for X1 ? Route 66 is pretty anoying some times....
X1 GPS
After deleting the fails xtra.bin my gps start to work for now, but I want to ask do I have to use quickGPS update if I update the gps from there the problem will be start again
Yes delete xtra.bin helps!!!
Does anyone has older version of quick gps. I still want to use quick gps, becasus waiting for gps to fix is annoying. thanks
Hi all,
After deleting the xtra files and confirm that works i went out, and during the driving i used the GPS.
Even went going out of the car and switching GPS programm off, as soon as i got back into the car and switch programm on, the GPS location came so quick that was unbeleivable. Only time to switch it on , put it into the older start the car and when i look into it, was already navigating.
So my advice is FORGET about Quick GPS.
I think ESA as lunched a new GPS satellite for the European system, I wonder if has anything to do with with it. ??? Anyway it's great !!!
No, ESA satellites are not primary GPS satellites. They provide WAAS/EGNOS correction info only. AFAIK Xperia does not support correction, so it does not work with these satellites at all.
The problem could be with QuickGPS data. Many users started to have the problem at the same time. It seems xperia uses QuickGPS if they are available. So any corruption on QuickGPS side makes GPS unusable.
Sometimes just forced QuickGPS reload helps .. but sometimes not, and that's when the trick with xtra.bin comes handy.
Thank you all in this awesome forum. Deleting the xtra.bin files solved the problem for me. Even the time to log the gps position seems not really to be slower in my case
Hi Dr Sid
Thanks for the explanation.
My point was that the xtra.bin removal works, and after i did that the GPS position was found very very quickly without starting Quick GPS.
I wonder why because, before it would take 10 minutes or more, if quick GPS was not used.
Summer time change?
Hi
I was wondering what is wrong with xtra.bin. It is downloaded from web server xtra1.gpsonextra.net or simmilar.
In my country (Slovakia) at 24-25.10. there was time change from summer time CEST (GMT+2) to CET (GMT+1). Maybe it is some dependance between change of time and GPS problem.
Wiki says same time change is all over Europe.
All of you with same problem, please check registry, what servers are set in QuickGPS. My phone is HTC, so registry are there:
[HKEY_LOCAL_MACHINE\Software\HTC\QuickGPS\0\0]
"port"=dword:00000050
"IP"="xtra1.gpsonextra.net"
THANKYOU SO MUCH!!
This has been driving me crazy!! I have only just learned to put ROM's on my phone and this is when the problems started, so I suspected the ROM's was causing the problem.
Deleted the 2 files and now my GPS works perfectly.
Excellent fix, saved me so much time.
THANKS THANKS THANKS !!!!!!
Works for me too (Buenos Aires - Argentina).

It's very probable that this is the problem, since I have it since a few days also. But it's strange, last time change I had no problems with it.
hehe, a bit slow to find this thread
yep the quickgps data is corrupt somehow.
took me a lot of reboots to find this out.
A-GPS still works just try running google maps with GPS turned OFF!! you get a rough idea of where your are.
QuickGPS gives a weeks calcutions of predicted GPS satalite locations which can then be used to reduce the cold-boot gps startup time.
If you live near the coast at all, your GPS chip will also pickup the land based stations that broadcast static information which helps in the accuacy of location.
It is quite possible to live without QuickGPS, it just makes the startup time anything upto 2 minutes.
However, with quickgps being used for so many phones, it should not be too long before its all fixed again
It's just pity it can't be disabled by some normal means. If you delete the file, QuickGPS will load it back next week.
Also it could try to compare data from the file with data from the satellite. If different satellites are visible than those which should be visible based on the file, than GPS could realize something is wrong. It does not.

I've had this problem too. While my dad was using Google Maps and getting great and accurate GPS location that picked up our signal inside Heathrow airport, mine was telling me we were over 3000 km away. I too would like to know.
download the latest satellite map and let it get a good lock, first time takes forever.
the GPS is only supposed to work if the phone has a clear view of the sky.
sometimes it will work with small interference (a car's roof for example) but inside a building you wont have any luck
make sure to enable "Use GPS" and not triangulate by signal
Never had any issues with GPS. If you have downloaded quickGPS data, it takes in matter of seconds (about 20) coldstart, hotstart is pretty much immediate. Without quickgps it is in terms of minutes, usually about 5 mins tops for coldstart. Hotstart is, depending on how far are you since you last time used GPS and how long is it, matter of seconds.
Hi there,
I used to have the same problem and I tried almost everything. I used different GPS tweaks which can be found in this forum like "turboGPS" but these would never work that well for me.
I found a great solution yesterday right here: http://forum.xda-developers.com/showthread.php?t=571266
Install the "GpsModDriver_320.CAB", follow the instructions, softreset, start the program you just installed and watch your device find the sattelites within seconds.
Just read the instructions in the link attached above.
have fun!
This should really be in the General forum, it's not a ROM development issue (or you could check in the specific thread for your ROM if it's a custom one, in case anyone else has GPS issues).
it works! i love you guys!
