I'm just started (yesterday) coding an application in Cocoa for use in a MacCarPc. This will be built into my Acura RSX.
Features of the program:
- Phone (via bluetooth)
- GPS (hopefully)
I'm not sure exactly how the sleep function will be triggered when the car is turned off. Success of the program will depend on both figuring out/finding a GPS system, and getting sleep to work without draining the car battery.
