SXG75 NMEA access via Bluetooth

[DireWolf]

I have searched everywhere and can't find a solution: every SXG75 owner knows that the phone can act as a USB GPS receiver for the computer, using the "BenQ Siemens NMEA Device".
However, I'd like to connect it to my Bluetooth PDA to use software like Route66, TomTom and WiFiFoFum.
Of the three interfaces the phone presents when connected via cable, only OBEX is available via BT. Isn't there any way to change which interface is active? Not only it would allow GPS via BT, but also programs like Brew Mobile Commander wouldn't need a cable.

i need this function too,but i guess siemens had done nothing with GPS via BT for the bad brew develop environment

With Portmapper you can change Diag to BT...

But NMEA ??.

Yeah, some time after posting the first message in this thread, I found out about the extended FieldTest menu.
So, since there is a hidden way to remap BREW access to BT, maybe there is also another (so far unknown) way to do the same with NMEA?
