Reverse wire input for Sat. Nav

Recommended Posts

After much searching, I still can't find a reverse/backup light input wire for my Pioneer Avic sat. nav. My car is a 2000 model, so doesn't have this input wire to the existing radio and neither does it have a black/blue wire under the seat, as other people have instructed. I really don't want to have to run another wire all the way from the tail light if I can help it. Does anyone know of anywhere else I can find a reverse signal wire?

If your car is equipped with an automatic downward tilting passenger outside mirror when in reverse, take the signal from there. If not, the reverse light switch wiring on top of the gearbox seems to be your nearest option.

The blue/black reverse wire is in the bundle that goes to the module under the drivers seat, but you have to peel away the cable bundle wrapping to find it. It is about an inch from the connector.

If your car was originally equipped with PCM1 nav unit, the black/blue wire is on the nav cdrom connector.

BTW connecting reverse wire to a new nav unit *might* be of use, since the stock navigation does use reverse wire for better positioning (along with accelerometer).

I know this is an old thread but thought I'd just confirm my recent findings in case anybody else is looking to do the same in future.....

My car is a 2002 996TT which originally came with PCM1 installed. A few months ago I removed this and fitted a Kenwood DNX-7230DAB in its place. I then decided to add a reversing camera to this installation which I fitted yesterday. In order to get the Kenwood to switch to the rear view when the car was put in reverse I needed to access the black with blue stripe wire which I was going to do under the passenger (left as I'm in the UK) front seat. However after reading this post, I checked the redundant white connector behind the dashboard which used to go to the Nav CDROM where I found the black/blue wire.

System works perfectly after tapping into this wire at that point :thumbup:
