The wiring still reached but it was not pretty. For the antenna side wires. only the white USB and black bluetooth antenna need to be connected. Open the hatch in the rear and post a picture.

Photo attached. MULF and TCU wires facing the same way.

And there are plenty of aftermarket carplay options out there. Just not a factory one for CIC.

Yeah, I understand that. I was saying that I'd rather go COMBOX route than tune2air for Bluetooth audio. Now the question is, is it worth looking for the Gen 2 COMBOX with 4g or since I'm not planning on subscribing to BMW Connected Drive 2g would be fine.
