The only tricky part is routing the four wires for the CAN termination resistor and the BCD to the front right footwell. The rest is fairly straightforward: you simply need to run some cables from the connector near the trailer hitch to the electronic control unit (ECU) in the rear of the vehicle. All in all, it's a job that takes about four hours. I recommend getting wires from a donor vehicle with the pins already crimped on.
It's basically "plug and play" – so you don't need to worry! 
You can try all regions until you find one that works with your door/remote. Mine worked with US setting.
Ich habe sehr, sehr gute Ergebnisse erzielt, indem ich einfach die unter den Sitzen verbauten Tieftöner durch die „Ghosts“ von BAVSound ersetzt habe. Meiner Meinung nach sollte das der erste Schritt sein, da es die kostengünstigste Maßnahme ist.
Hello everyone!
Given the current hype surrounding MGU apps, I'm working on my own application to control the rear climate control, sunshades, seats, and rear-seat entertainment (RSE). The technical implementation is complete, but the user interface still lacks proper integration and the typical OEM look and feel. I'm searching for the original graphic elements used in the app for the rear-seat tablet – but haven't been able to find them anywhere yet.
You seem to be the only ones with the necessary know-how to implement something like this. Since I've mostly been a silent reader and haven't yet made an active contribution to the community, I unfortunately can't access the resources you've kindly shared. Would someone be so kind as to provide me with the files via an external link?
