I wish to install a SONY XAV AX1000 HU into a 2103 RTL with navigation and the OEM backup camera. It seems the connections are at the DVD unit under the driver's seat. I also understand that the OEM camera is 8 volts and so will require a transformer wired in-line.

So if I understand correctly I will have to identify the four wires for the camera (Camera +, Camera -, Video + and Video -) and tap into the harness that holds them (under the driver's seat). I'll need to also identify the reverse signal wire. All these need to be run into the dashboard to connect to the HU.

To move from under the seat to the dash, could I tap into the disused harnesses for the OEM Navigation which will no longer be used?

All this because I imported this vehicle into Europe, only to discover that the navigation doesn't work outside of North America and there is no opportunity to get a nav DVD for europe. :(

Thanks for any advice.

Roger

@Martini I actually did this exact thing with my own 2013 Ridgeline w/ Navi when I installed a Pioneer AVIC-W8400NEX. All you need is an RCA wire with one end trimmed to reveal the video positive and negative wires and tap those into the corresponding wires under the driver's seat. You were correct in identifying the four wires that interface with the camera, but you actually only need to tap into the white (video positive) and black (video negative). This pic illustrates it nicely:

This particular connector is the flat 7 pin Connector E mentioned in the attached wire diagram. When you've tapped these wires plug it back into the DVD unit and make sure all connectors and wires are still intact as this is needed to maintain camera power and functionality.

Most RCA wires for backup cams come with an extra red wire bundled on the outside of the pin, and you'll want to connect this to your reverse sensing wire on the back of your head unit and the reverse wire which is also conveniently located under the driver's seat DVD unit. The reverse sensing wire is a solid green wire illustrated below:
