@GhostWolf said in Tomtom linux:

The reason I wanted the TomTom was because I just have it laying here, and the programm doesn't have to be fast. The only thing it needs to do is to send data if I press a button on the screen.

As @Wieland already said, most likely nobody here can help you with this. So even if it's possible (from hardware side) to do what you want, you're on your own.
