I recently bought a program that is designed for wince 5/6 based GPS units. It unlocks the desktop and allows the ability to attach either a wifi adapter or OBD2 adapter. (this allows you to view engine diagnostics, fuel consumption, speed, etc...). anyways the website is WinCE Patch. love the software hope this isn't a re-hash of an old thread but just really wanted to give this guy a little help. oh ya the cost is around 20$...recommend it. either way check it out he has video's of the functions.
