Rand McNally GPS Hack
If you can get your hands on a Rand McNally GPS this Rand McNally GPS Hack will show you how to get the serial data out of it. Since these GPS devices are quite old now they should be quite cheap. Does anyone know of a cheaper serial GPS solution? If so please share it with me. 
“Buy a RandMcNally GPS for the Palm III from http://www.randmcnally.com The GPS circuit board is held on to the sub circuit board by a to the sub circuit board by a 5 pin header. Since I did not have a big fat solder iron tip, I held my solder iron accross all five pins, and slowly worked the boards apart slightly. When there is enough room, bend the circuit boards back and fourth untill all five pins break. Be carefull not to over stress the circuit board. If you have a better solder iron, or patience with soaking up all the solder you can easily improve this method. I then removed each individual pin that was left broken in each hole.”
