I don't really know. I have a TomTom One and would love to be able to 
plot something on the screen. I use a separate small PGM-110 from 
Polstar for APRS. I'm not so much interested in using the TT1 as a GPS 
source for APRS (It's not always in the car), but feeding data back into 
would be nice.
The TT1 does behave different when it is plugged into a PC, but that has 
probably to do with how it is initialized by the PC.

Is there info about the TT1 interface available or is the as closed as 
can be?
