gm onstar hacking

onstar serial hack

this site shows you how to jack in to the gps receiver inside any gm onstar system.  it’s as simple as soldering a up a serial cable.  you can then connect to it and either run some gps diagnostic software, or switch the device to nmea mode so that you can use it with your gps mapping software in your car pc.
