How to activate AUX in Audi concert

Audi A5 2007 for example

Audi Concert AUX pinout here

There is port for aux in behind your CD player and also you need VAG com machine for activation.

So use the VCDS to code the car and activate AUX menu, after that you can install our product.

Here is the VCDS website FYI: https://www.ross-tech.com/index.php

I recommend you take your car to your local AUDI dealer to activate the AUX feature first, then you will be able to install our product.
