hi there guys, I'm the owner of a 4l q7 2006 diesel. at some point the car had PlayStation but previous owner took it out. now, I still have the 2 options AV1 , AV2 and got the av rca cables in the boot. my question is can I somehow use this system to install a reverse camera? as from what can find online there are some camera kit with modules with a av input. any ideas how to do this?
