Ok - so I installed my AVIC-D2 a while back and couldn't find the reverse wire. I didn't connect it and things seem to run fine but I've heard the car really needs it to track reversing and keep things where they should be. Does anyone have any good ideas about how to find this wire without going totally nuts on things? Let me know. All the tips I've seen are incorrect, incomplete, or wildly vague.
