Audio 20, code 523
According to the Mercedes dealer my audio-20 is in accordance to MB code 523. What is the meaning of code 523?
I also noticed that there is no AUX in glove compartment or AVI in storage area. There is in the back corner of the glove compartment a hole.
I think there was once a AUX cable. Base on code 523 do I have the 10 pin connection or the 4 pin connection?
I like to upgrade my audio, or change harness and monitor from 5.8 to 7", to add a backup/parking camera.

Thank for the help
