Many may ask why would you want to do something like this anyway. For most the question is moot; simply being able to prove you can is sufficient motivation. Others put forth practical applications - for instance, outputting GPS locations via Bluetooth to a WiFi-enabled laptop, thus pinpointing precisely where open WiFi networks are located. And others imagined how nifty a tiny touchscreen media player could be, particularly with its built-in SD slot and loudspeaker.

The key to it all is Linux. The TomTom GO runs Linux, specifically a custom distro called TomTomLinux or TTL, with an ARM processor. So, logic dictates, if you can compile a program for Linux on the ARM then you can run it on the TomTom.
