    New to the forum and was hoping for a bit of help. I have a MK6 Golf GTD and have recently fitted a new head unit to get a few upgrades as well as fix an issue I experience via Bluetooth. I originally had a RCD 310 head unit, now I have a RCD 510. The issue I still have is when Reverse Gear is selected on the car and the parking sensor beeps kick in, when Bluetooth music or a phone call is in place the music or call volume dims for the sensor beeps and then doesn't come back when drive or sport gear is selected.

    When removing my head unit and installing the new one I noticed how the wiring has previously been tampered with hence the red tape in the picture below, anyone know what this cable does?

    Thanks In Advance
