Need Urgent Help!! XDA2i + Globalsat Bt-338 + Tom Tom 5

THIS IS A URGENT!! NEED A FIXED B4 THIS WEEKEND!! ANY HELP ARE MUCH APPRECIATED!!

Hi all,

I have a XDA2 i, Globalsat BT-338 and Tom Tom 5.

I have just installed TomTom 5 and the software
works fine, i cant seem the unit to register that there is a gps unit present.

I have installed Tom Tom GPS v3.07 and it paired with Sirf 38400 and bluetooth Serial port Com6 with good signal.

But when tomtom config is entered it still registers no gps unit.

Have tried both bluetooth ports , little spinning disk works on screen but
still says "no gps device" (only on port6).

many THANKS!!
