So, I have a Base system F20 LCI, which I want to upgrade with an amplifier.

First problem, I have no BMW amplifier in the back, so I can't connect to the existing cable in the back, as it does not exist.

Bimmertech ships a cable which runs from the Headunit to the back, however, here comes the second problem.

I have a Android Auto/Carplay box already connected between the quadlock and my headunit, so I have no idea how having another connector connected as well, would work.

Does anyone have a solution to this?
