Hey,

This will be an odd one... but I want to interface an external device to the navigation... is there a serial port with NMEA GPS data on it? That way I can hook it to the APRS tracking system and get the other cars in my convoy on the maps too... would be cool... but?

Interesting

I am not sure if you have any aviation background, but this is almost at the edge of TCAS.

TCAS for those not in the know is: Traffic Alert and Collision Avoidance System.

It would be very kewl to see others close by, a little useless but cool none the less......
