I'm working on a program that logs many things including GPS position and V1 data (also the J1850 datastream from my harley, or the OBD2 stuff from my car).
I'll post some examples in a following message (I don't have enough posts yet).
My remote display is currently my Nokia N810 internet tablet with a program that shows the display (unblanking the screen and coming to the front when it detects something).
The whole datastream is saved off in a KML file (but only for post processing).
Note the data is available live, or with a replay program (I can watch where I was through google earth while my instrument cluster and V1 virtual display on my laptop run).
Right now it is opensource so runs under Linux, but can run on Mac or Windows with the right software.
It would be nice to do something like uploading the contacts, but what would people here find useful.
