Hello all - new guy, first time poster. My US spec Xdrive40i is on a boat to Germany currently and I'm planning on replacing the Harmon Kardon with an entirely new set of speakers. I've currently got a loaner 2021 530i and am unimpressed with the HK system.
Wiring schematics for the iDrive7 system are pretty hard to come by. Focal has one but it's pretty uninformative. Does anyone know where the iDrive7 source signal is? (
Looks to be under passenger seat from the Focal Diagram) I'm looking to take the source signal and pipe it to a couple amps for more juice in the system. Any ideas?
