Well, now I have a few more crazy ideas.

1. Buy a bluetooth gps, cut a few traces, and splice in the elmscan.
2. Buy elmscan usb, use with 770, wait for n800 to support usb host.
3. Buy elmscan usb, use 770 as bluetooth serial adapter.
4. Tap n800 internal serial port and mutilate battery door.


2 and 3 seem like the best solutions. I could probably add a switch and 2 pieces of wire to the elmscan to inject power to the 770.
