Hello friends, Roman from ACSByRoman.com here. Im updating our old Mr12Volt threads as there is a lot of new info since we first came onboard with Rennlist. The current thread will reference strictly Mr12Volt P3000 systems. We are doing this to avoid any confusion regarding older systems.

If you have an OEM 360 camera, can you instal this and maintain the OEM 360 camera function within the PCM3.1. aka when I put the car in reverse will it automatically switch over to the OEM 360 camera screen and function? I just wanted to clarify if the cameras will have to be added in the mr 12 volt interface, or if I can retain PCM3.1 function.

The diamond "joker" button remains inoperable. This is like the guages not showing maps from carplay... something I think we will never be able to accomplish. As far as im aware, its not in development. Your volume and phone call buttons should work.
