I have a family member making a 18 hr drive home for Christmas tomorrow. I'm curious if there's a FlightTracker style app or gadget that would allow us to track his progress on our PC/TV screen, based on his GPS, much like you see on some longer-haul flights? He doesn't have a smartphone or any other tablet/etc device, so it would need to track via his GPS. It's a basic Garmin dash mounted model. So, any way to do this?
No. A regular GPS is receive only. It doesn't transmit anything.
