Want to keep track of your trips from anywhere you are? Here’s a DIY GPS to SD-card data logger/compass by Ktulu:
Earlier this year I have bought on the flea market a used car GPS system, an Amstrad gp1000. (Un)fortunately it was so badly damaged, that it could not be repaired, so I thought I would reuse some parts from it. Then came the idea of building a portable GPS logger system.
Check out the video after the break.

Might make a nice add on for older vehicles.
I want to buy this project with demo and documentation.
Please give a reply.
