I understand correctly, I've had problems with getting the serial connection in the car to work. Putting a cigarette adapter in for the laptop solved that problem. I actually had a seperate grounding wire before that. Every device I've tried was powered on the cigarette adapter and I tried batteries-only as well. Still the same depressing result... I hope nothing is broken...
