GPS Chip replacement in Nokia N 97
I am aware now that there are many N 97 owners having problems with thier GPS .. i was wondering if anybody has had the chip replacement done that Nokia are offering for free ( i have read this on here)
if anybody has had this then can you please reply and give me some details of how long it takes and if you did actually get it free or pay for it .. if you had to pay for it can you let me know how much it cost?
thanks guys
Have you installed the new Ovi Maps 3.03 ? I haven't had gps repair , but signal is much stronger with new maps ! Don't know why, but it is.

If I am not mistaken, phones like 5800, N85, N79, etc has the [B]NL5350[/B] GPS chip but [B]how many dBm works?[/B]
And models like N82, N78, N96 use the [B]NL5300 GPS[/B] chip not? [B]how many dBm works?[/B]
Thk!Nokia has not published any detailed specifications that'd state which GPS receiver chips are used on various models.
I don't know how easy or difficult it'd be to identify the chips if you dismantle the phones (often the actual chip markings do not identify which/whose chips are in the phone).

Other than the GPS chip in ipad 2 wifi+3g...
Are there anything else the 3G version has that a regular wifi only doesn't have?
I am still having a tough time deciding which one to get tomorrow. I already have a data plan on my iphone 4, but it would be nice to have the option to add a data plan to the ipad 2 in the future.
The thing is they release these every year, and I don't see me getting a data plan on the ipad anytime soon. If I need data on it I'll get it on the ipad 3 or ipad 4 :-D
Sorry for rambling on, so basically just wondering what other benefits there are to the 3G version besides that GPS chip.
On a side note, in NYC which one of the Apple stores will be best to avoid long lines tomorrow?
I'm closest to the SOHO location from my workplace. I'm assuming the 5th Ave one will be crazy.
Thank you in advance.I can't believe you missed the most obvious difference?!?
The Verizon and AT&T 3G/GPS chips add 6 & 12 grams respectively. -
Reading bluetooth GPS data from a Nokia phone
I have a problem reading data from a MTK bluetooth GPS device from a Nokia phone (7610, Symbian S60).
I wrote a midlet (my phone supports CLDC 1.0/MIDP 2.0) that create a thread to read data
from the device (using RFCOMM protocol), the code is:
package gpsreader.bluetooth;
import javax.microedition.io.*;
import java.io.*;
public class BTrxtx implements Runnable {
private String url = ""; // Connection string to the bluetooth device.
private boolean canRead; // True if possible to read from device.
private boolean canWrite; // True if possible to write to device.
private String btstr = ""; // Last received string.
private int strCounter;
private int byteCounter;
private StreamConnection conn = null;
private InputStream inputstream = null;
private OutputStream outputstream = null;
private boolean newStr;
private static final char[] EOL_BYTES = {'\015','\012'};
public BTrxtx(String u) {
url = u;
canRead = false;
canWrite = false;
strCounter = 0;
byteCounter = 0;
newStr = false;
Thread t = new Thread(this);
t.start();
private void openInput() {
canRead = false;
try {

canWrite = false;
try {
outputstream = conn.openOutputStream();
canWrite = true;
}catch(Exception e) {
setBtstr("oout");
System.out.println(e);
private void openConn() {
try {
conn = (StreamConnection) Connector.open(url);
openInput();
openOutput();
}catch(Exception e) {
setBtstr("oconn");
System.out.println("Failed to open connection: " + e);

try {
if(inputstream!=null) {
inputstream.close();
}catch(Exception e) {
setBtstr("cin");
System.out.println(e);
private void closeOutput() {
try {
if(outputstream!=null) {
outputstream.close();
}catch(Exception e) {
setBtstr("cout");
System.out.println(e);
private void closeConn() {
try {

closeOutput();
if(conn!=null) {
conn.close();
}catch(Exception e) {
setBtstr("cconn");
System.out.println(e);
public void run() {
openConn();
try {
Thread.sleep(200);
}catch(Exception e) {
try {
int i = 0;
char c;
String s = "";
// Start reading the data from the GPS
while(canRead==true) {

c = (char) i;
s += c;
System.out.println("GPS return no data");
setBtstr("BTend");
}catch(Exception e){
setBtstr("BTrun");
System.out.println(e);
private String byte2hex(byte b) {
char[] alphaHex = {'0', '1', '2', '3',

'8', '9', 'A', 'B',
'C', 'D', 'E', 'F',
int low = (int) b & 0x0f;

public String getBtstr() {
newStr = false;
return btstr;
private void setBtstr(String s) {
newStr = true;
btstr = s;
public boolean receivedData() {
return newStr;
The problem is on method "run" at line:
i = inputstream.read(); // read one byte at the time.
after reading some data (usually one NMEA string) read method returns -1,
and even if I try to close the connection and re-open it, after some other data is read,
the midlet is terminated by the phone with an error (something like "jes-13c-java-comms@1441adE32USER-CBase 40").
The GPS receiver is working, since from my PC I am able to connect with a bluetooth USB dongle and read outputs using RFCOMM.
Thx for any suggestions,
LB.Work around.
I can not say I solved it, but I managed to get a work around:
I read in another post that there are some problems in thread handling on Nokia phones, so I rewrote the class so that it runs on the main thread and now it seems to work (I can not update the screen while reading from the device, but this isn't a big issue for me).
Just in case anyone is interested here is the final code:
import javax.microedition.io.*;
import java.io.*;
public class BTBrxtx {
private String url = ""; // Connection string to the bluetooth device.
private boolean canRead; // True if possible to read from device.
private String btstr = ""; // Last received string.
private int strCounter;
private int byteCounter;
private StreamConnection conn = null;
private InputStream inputstream = null;
private boolean newStr;
private String s = "";
private static final char[] EOL_BYTES = {'\015','\012'};
public BTBrxtx(String u) {
url = u;
canRead = false;
canWrite = false;
strCounter = 0;
byteCounter = 0;
newStr = false;
openConn();
try {
Thread.sleep(200);
}catch(Exception e) {

canRead = false;
try {
inputstream = conn.openInputStream();
canRead = true;
}catch(Exception e) {
setBtstr("oin");
System.out.println(e);

System.out.println(e);
private void closeConn() {
try {
closeInput();
if(conn!=null) {
conn.close();
}catch(Exception e) {
setBtstr("cconn");
System.out.println(e);
public void readInput() {
try {
int i = 0;
char c;
// Start reading the data from the GPS
while(canRead==true) {
i = inputstream.read(); // read one byte at the time.
if(i==-1) {
closeConn();
try {
Thread.sleep(200);
}catch(Exception e) {
openConn();
try {
Thread.sleep(200);
}catch(Exception e) {
continue;
byteCounter++;
// Every sentence starts with a '$'
if(i==36){
if(s.length()>0) {
strCounter++;
setBtstr(s);
s = "";
c = (char) i;
s += c;
return;
c = (char) i;
s += c;
System.out.println("GPS return no data");
setBtstr("BTend");
}catch(Exception e){

System.out.println(e);
private String byte2hex(byte b) {

'8', '9', 'A', 'B',
'C', 'D', 'E', 'F',
int low = (int) b & 0x0f;
int hi = (int) (b & 0xf0) >> 4;
String res = String.valueOf(alphaHex[hi]) + String.valueOf(alphaHex[low]);
return res;
public int getStrCounter() {
return strCounter;
public int getByteCounter() {
return byteCounter;
public String getBtstr() {
newStr = false;
return btstr;
private void setBtstr(String s) {
newStr = true;
btstr = s;
public boolean receivedData() {
return newStr;
Now I call method readInput in the main thread and than use getBtstr to retrieve data.
I'm still interested to know if someone had similar problems and how they have been solved.

What is GPS chip in new iPhone 3 GS ?
Do you know any ,what type of GPS chip is in new iPhone 3 GS ? The same, as in previous 3G or any new- better ? With GPS chip in 3G are a little problems time to time....
Info seems to be here:
http://www.appleinsider.com/articles/08/07/12/everyiphone_3g_chip_named_illustrated_indetail.html
Oops .. that's the 3G
There may or may not be info on the 3GS here:

So............. I contacted a Apple rep to find out if I wanted to upgrade or not and come to find out with a ton of pulling of info she told me that there is no GPS chip and that the GPS is nothing more then a software update in which we all will get including the old IPhones. So really the only update for the new 3G is just that.... 3G. That's it. Now maybe she did not know what she was talking about but thats what she told me.
Anyone else confirm?Also just go look at the specs
http://www.apple.com/iphone/specs.html
And info what A-GPS is (assisted)
http://en.wikipedia.org/wiki/Assisted_GPS
The A (Assisted) part means, it has GPS yes, but GPS in general has issues around tall buildings etc, so gets assistance from servers. So while assisted makes it better (especially in cities etc...a lot of driving units have this) it also has to have a signal to your network (cell signal) to get help. Not a bad thing and normal. Just means don't expect to use the phone in the middle of a mountain trail while hiking.

N96 GPS Chip - Possible to remove and reuse?
Hi,
My N96 has died, and am looking to get another phone - found the N96 too slow to bother repairing. However I was thinking about taking it apart and trying to use the GPS chip.
1) Is this possible? - I've not looked inside yet
2) Does anyone know what chip it uses - is it easy to reuse?
Thanks
MarkThanks for this, though after looking at it I'm not too inclined to use an app that requires getting into the terminal. Way too technical for me. But thanks.

Is the GPS chip only available with the cellular LTE iPads??
I was wondering if the wifi only ipad 3 also included the GPS chip or not?
If you need built-in GPS capability then yes - though there are some stand-alone GPS units that apparently work with it e.g. Bad Elf (I haven't got it so I don't know how good it is).

Does the ipad mini retina have a gps chip?
I do not find this info under the specifications, consequently, I suspect that it does not. I'm willing to buy one, if they do.
Only the cellular versions of iPads have GPS chip.
So the Mini retina with Cellular does have a GPS chip yes.
The Wifi only version does not. -
GPS chip in the fourth generation iPhone
Does anyone know if the GPS chip in the fourth generation iPhone is the same one that is in the iPad or the one from the iPhone 3GS? The iPad chip is much better.
Yes.
GPS signals are separate from and completely unrelated to both the Internet and the cellular telephone network. GPS signals come directly from the GPS satellites. They provide signals that allow GPS receivers to calculate latitude and longitude information. Navigation software then takes that latitude/longitude info and converts it to land mass, roads, bridges, highways, buildings, etc.
Most navigation software stores the maps right in the iPad/iPod/iPhone but a disadvantage is that the maps must be periodically updated (perhaps once every two years). The Internet is not required to use the system but it is required to update the maps.
Some navigation software gets the maps from the Internet and requires an Internet connection to function but an advantage is that the maps are always up-to-date.
The WiFi+3G/4G iPad and the iPhone both have a GPS receiver. The WiFi-only iPad and the iPod do not and these devices require an accessory. -
Thankfully I noticed this issue sooner than later with my 3gs:
When comparing to my 3g after a full restore and with Wifi off and Airplane mode on, the 3gs fails to acquire any satellites entirely.
Maps reports 'location cannot be determined' and XMotion GPS shows 0 satellites in the list.
The 3g being held in my other hand under the same conditions acquires in 5 seconds and provides a full fix with 1 meter tracking within 20.
I did not notice this issue immediately because I had not tested with Wifi and cellular turned off. My symptoms with these features on was simply, "jumpy" performance on Maps when tracking. I knew something was up, so I began testing...
Both phones are on 3.0 and I did test after a full restore and after resetting Location settings on both devices.
Anyone else with a 3gs getting 0 connectivity from the GPS chip? Please test it with aGPS off (i.e. no wifi + Airplane mode) My device is week 27 and has the yellow screen as well.
Message was edited by: wintermutefaI started this thread because my issues is neither about 3.0 problems with GPS or mismatching between the aGPS features and the GPS chip.
Please let me be clear that this post is about non-functional GPS CHIP within the 3gs, not the aGPS features conflicting.
My 3gs is unable to acquire satellites entirely, the list in XMotion GPS is always blank.

GPS LD-3W and nokia 5800 charger
hi , i have a nokia 5800 and a wireless gps module ( LD-3W) .
in bundle for Gps i received a DC-4 car charger but i need also charge GPS module at home .
May i use the nokia 5800 charger for this ?
i remember that :
5800 charger is 5v/890mA .. and GPS charger is 5,7v/890 mA
thanksSomeone asked so;
My 5530 charger works fine charging the LD-3W; its because nokia only every 1 of 2 chargers the large tip or the small tip.
Yes the LD-3W works really well and except for the LD-3W having some extra battery life I heard that the 3w and 4w are really quite similar.
I am not too sure on the specs of them for accuracy and positioning but when i use mine it updates quite quickly (with only little jumps while in my car) and it gets the right position all the time.
I believe the LD-4W should work fine with the 5530 also.
And if you do not have nokia/ovi maps then you should get it. Its free and it has full navigation now.
Ovi Maps
++If you have a 5530 you have to download the 5800 maps application from here;
http://maps.nokia.com/ovi-services-and-apps/ovi-maps/downloads#/nokia-5800-xpressmusic/
Its up to you but I just choose download from pc which is at the bottom as it wont cost you data charges etc for using you mobile.
++Next install the app on your phone
++Now thats it just install ovi suite from here;
http://europe.nokia.com/support/download-software/nokia-ovi-suite
and choose what maps you want to download and by choosing update you can check your app is up to date.
Most of this info above plays to the 5800 aswell

Problems replacing a nokia 6230i on a BMW 525i
I will try to be brief. Having recently purchased a BMW 525i the car comes with a standard Nokia 62301 I was forced to abandon my Sony Erricsons K700i and P900i as they would not work with the included car kit. The 6230i broke down after 3 months and was replaced under warranty. The problem is the limitations of the 6230i synchronization, first name last name problems etc. 1-Can anyone please advise me on what phone Nokia or any other brand that is compatible with the BMW car kit , that will automatically download the phone book every time I enter the car and which has features equal to or better than the Sony Erricson P900i 2- Is it possible (if one does find such a phone) to change the cradle in the car to charge this new phone. Any assistance Providing IT WORKS would be greatly appreciated. NB BMW were no help at all!!!!!!!!!
Hi calfo, I am sorry to hear BMW were no help to you, but Nokia will be no help to you either, most BMW car kits are not designed for fancy modern phones like your p900, a simple phone like a Nokia 6310i will work a treat. Your best chance is to find a BMW forum where similar owners have already made the mistakes.
sorry we cant help further but this is a very grey area for all of us.

I bought this phone mainly because it's big screen and GPS.
But it just doen't work. At all.
I left only GPS connection (A-GPS, Network etc. - are off).
In Satellites-Status is finds sometimes up to 5 satellites with gray bars. (as I understand it means weak signal) and then nothing happens.
Last night I went to railway station, which is high. The sky was absolutely clear with stars.
No high buildings around. I holded the phone in the center (not to cover the antenne).
And nothing happened. Only 4-5 gray bars maximum. Even after 10 minutes.
I'm thinking about sending it back.
Another problem - is one of the most stupidest programs I've ever seen - OVI-Suit.
Absolutely illogical, insanely slow and fulled with mistakes.
(The only program which is worse is Corel Draw Painter).
And please, tell me someone, why the Options for GPS are in the Menu-> Applications-> My Position-> Options,
but the Maps themselfs are in Menu-> Maps?
I've heard just yesterday, that Nokia looses its market share very fast.
And somehow I understand why.Hi DexterStJock
If you are not going to utilize the Assisted GPS feature and rely solely on Integrated GPS you can expect initial positional fix to take a considerable time to acquire but subsequent lock-on will be much more rapid. If you haven't yet got a satellite lock-on don't expect a new location to be better as you could be anywhere in the world as far as it is concerned. Unfortunately GPS antenna size within a mobile device has to be compromised due to space limitations and unfair to compare with car sat nav unit.
You are correct that "Positioning methods" are found in Menu > Applications > Location but this is independent of OVI Maps as other applications can utilize it's features.
Happy to have helped forum in a small way with a Support Ratio = 37.0 -
