To bigin with I actually installed a AUX cable from my RNS-E running to the small container to the left of the steering wheel. I however usually use SD Cards for playing music so the AUX is only used when I have guests in the car. Therefore it was an issue having the AUX in the drivers side and now that I was planning on changing to the US Center Console it did make a lot of sense to move the AUX at the same time.

Installation & Guide

The installation was done by (Denmark)

I found this guide which I think most people will be able to follow.

INFO: The guide is of course a bit different compared to purchasing the finished AUX cable as I did
