Hi everyone, I'm working on a custom ESP32 Bluetooth integration for my 2010 Audi A3 8P (Facelift).

My car is equipped with the RNS-E Gen2 PU (8P0 035 193 G) and the factory Phone Cradle (8P1 862 401 D). I am trying to tap into the 12-pin black connector at the cradle (photo attached) to get Infotainment CAN High/Low and Ignition 12V power. Does anyone know which ones are the pins for the CAN High/Low, the 12v ignition, and the ground on this connector?

Also, I want to test this build on my workbench, but I don't have the RNS PIN. I've tried both eBay and onlineradiocodes.co.uk and none of them have been able to help. The serial number of the unit is AUZBZ7KD207675. Any suggestions on how I can get a hold of the PIN? Thanks very much!

Those wires goto the roof sharkfin for the pinkish fakra antenna & black goes directly to your oem BT unit, to get can & supply you need to grab it from the rns-e quadlock, can are the 2 orange wires & supply is on the same bank of pins, the rns has a label on the top that shows you which pin is for what.
