I was looking for information about E90's GPS antenna position, but instead I found this interesting document: N95_GPS_Connection_Guide_en.pdf

It doesn't really tell me any real new information, but I think it can be useful for some of the N95 users. Here's a quote from the document, how to create optimal receiving conditions:

The GPS receiver is located in the bottom of the device. When using the
receiver, slide the numeric keypad open, and hold the device at an angle of
about 45 degrees (as shown in the picture), with an unobstructed view of
the sky. Do not cover the numeric keypad with
your hand.

I wonder how the keyboard is supposed to be used if you cannot cover it with your hands - maybe it's for voice- and mind controlled GPS applications ;)

Several users have asked how the Bluetooth setup process goes for OS X Leopard -here's how!

Make sure ExtGPS is runnning on the phone. Open Bluetooth panel from System Preferences. If you have not yet paired your phone, press the plus (+) button, otherwise you can click on the asterisk (*) and select Edit Serial Ports.



Now the OSX connects to the phone and searches for new services. The serial ports screen typically has DUN service already setup by the Bluetooth wizard, now just click plus button to add new serial port. In my case, the first click adds ExtGPS port and all the settings are correct automatically:



Now ExtGPS is ready to be used, just use the given port name in your application.

In addition to the few screenshots I've posted, at least a couple of tutorial videos are found in the web. These show you how to connect ExtGPS and Nokia N770/N800/N810 devices:

Nokia Users: ExtGPS - Internal GPS Sharing for S60v3

The Mobile Gadgeteer: Use your Nokia N95 as a Bluetooth GPS receiver and modem for your N800

Guys, thanks for posting! I've always thought that the software is famous enough when it gets into Youtube...

I just realized that I have not uploaded any screenshots at all. Here's some basic screens of ExtGPS, taken on E90.

Firstly, the Bluetooth permission screen. If Bluetooth is not enabled, this is skipped and you will only get the Bluetooth error screen.


Positioning permission, allows accessing the GPS


The main screen, before connecting

About dialog. Running yet unreleased version ;)


And finally, the other device. In this case, it's E65 connected to E90. Not much point really, just to show that it is possible to connect two S60 devices:

If you are more into GPS navigation, you might also know that there's varying levels of navigation statements outputted by different GPS devices. In case you are pondering if ExtGPS on S60 device is suitable for your application, here's a sample NMEA data as outputted by Nokia E90.

Basically, the data contains location, accuracy, satellite positions on the sky, speed and heading - you rarely get more than this in NMEA 0183 format. Binary formats are of course a different matter...

PS. Extra points for those who can guess what's the most famous hotel next to this parking lot :)
