Hi everyone. Having just now hooked up the OEM reverse camera to the Carnaviplayer head unit, I would like to make a few corrections to Wrex's original post on the subject. All credit to Wrex for his original installation project but I think he made a few errors in the documentation and the installation so hopefully my notes help someone in the future.
Here goes:
1. The OEM camera module has two harnesses - it's the small brown one on the right with 4 wires that you tap into. There is no need to remove the camera module for the install. Just unhook the 4-pin connector and pull it out a bit and you will have reasonable working space.
2. The wires to tap into are WHITE/GREY for Positive RCA and BLACK for Negative RCA - Wrex's notes spoke of a solid White wire (there isn't one - he must have meant the white/grey) and solid Brown wire (there are two browns, neither solid, and neither are correct for use; he must have remembered wrong... we both have LP cars).
3. If you decide to repurpose a high quality RCA cable for this install, the outer copper wire bundle is negative, and the inner core wire is positive. But don't forget that the paper-thin aluminium shield is conductive and in contact with the negative, so you must peel it away a bit at the end to prevent contact with the centre wire when crimping.
4. The use of a 6V to 12V relay that caused much confusion and required much clarification in Wrex's article is NOT at all necessary to enable the centre console rear view camera button - the factory wiring provides a Pin 2 (being a white/yellow wire) on harness C (green harness with 12 pins) labelled RSFL and it outputs 12V whenever the camera is active. So simply bridge that wire to the Chinese head unit's reverse camera trigger and you are done! Camera button on centre console works, reverse auto trigger works. No relay needed.
