Ok found solution,
after spending way too much time on this crap! I finally found the issue as I stated I thought
it was a mobile 6.1 issue and I was right, in mobile 6.1 they have added a external GPS shortcut
in system tab it is here the problem exists.
my problem was resolved by the following procedure.
On your XDA go to Start/Settings/Connections click on Bluetooth short then add new device once it has found it
enter passkey 0000 or whatever yours is once it has made the first connection then do the following,
1. Under "device tab" click on your unit and make sure the serial port is "UNCHECKED" disabled then click save.
2. Under "Mode tab" make sure (Turn on blue tooth) and (Make this device visible to other devices) are "CHECKED" enable them.
3. Under "COM ports" select a port, I chose 0 don't think it matters but if so chose another but remember what one you choose.
4. Under "Security tab" Authentication (passkey) required "CHECK" enable it click ok to come out of Bluetooth.
5. Under "System tab" click on "External GPS short cut.
6 Under "Programs tab" select (None) for GPS program port.
7. Under "Hardware tab" select port 0 or same as you gave your Bluetooth com port and issue the "Baud rate" 115200 or lower rate.
8. Under "Access tab" Manage GPS automatically (recommended) "CHECK" enable
9. Finally check your xda is blinking a blue light and turn on your tom-tom software it should now pick it up, all done.
Final note it seems that Microsoft have made one more buggy operating system, no change there then LOL
and as a result you can't seem to use the blue tooth pairing process as intended so this is a working work around
one more thing there is a 2nd bug found and that is when you turn off your GPS unit and try to use your xda you might
find that your last page froze up here you will have to mess around with it i.e. try turning off your tom-tom software first
and then your GPS, Thanks to bill gates for yet another windows operating system that doesn't work as advertised.
Well we had Hendrix king of rock, Marley king of reggae, Elvis king of rock'n'role then there's you bill gates king of crap!
Long live the king!!!!! LOVL
