GPS: Working w/Live & Google - but never TomTom?

[Arclight]

hi everyone. I have no problems getting GPS to work in Live Search and Google, however I have never gotten it to work with TomTom 6. Is there something special people are doing?

I have it set to other NMEA GPS and Com 4 / 4800 - all the recommended settings. The only thing I ever see is no gps device found even if I fire up either Live or GOogle and the GPS is clearly working and tracking satellites - I can launch Tomtom immediately after and it shows no GPS device.

Tomtom works fine with my BT GPS module. And AstroGPSLauncher doesnt do anything for me. Any advice? Thanks.
