Connecting up a new HU, which has Reverse In (for backup cam) and Speed In (for dead reckoning GPS?). I've been searching and not yet found documentation nor thread discussion here that tells me where these wires connect. I'm probably blind Anyone have an idea? Thanks SO much! Edit: Solved the Reverse In question. Speed still left... Reverse is pin 29 of a 64-pin connector behind the kick plate near the left front door (near parking brake on LHD vehicles.) This link describes the reverse, and also how to wire a switch to get your pick of reverse-cam-only or always-on-cam. This link has photos.

Yes, it is. I just installed using this yesterday. When I installed, I used a T-tap and attached a long wire. Before I routed it to the radio, I used a Voltmeter to confirm that it received 12 volts when I shift into reverse, but not Park/Neutral/Drive. Indeed it does, and the backup camera works as expected.
