This is a 20P AV input/output cable made by Carrozzeria that I found while organizing my storage. Unfortunately, I don't know what it's compatible with. I'll list the input/output terminal details below. Outputs (RCA type) Subwoofer output (L/R) Rear monitor output Inputs Back camera input (5p) System remote control (blue/white, flat terminal) The connection terminal to the main unit is a black 20-pin (see photo) Does anyone know what this is for? 250804-1
