I think I actually have this plug somewhere. It's used on cluster panels and on a bunch of other stuff on E46 and E39.


I have a USB in the glovebox. Combox sounds like a better option. A bit more expensive, but more OEM and less dangling wires.

There was no CarPlay option on the E70. What people are proposing here is to install the NBT system instead of CIC. First X5 with NBT was the F15, which had the CarPlay option.

Most E70 do not need the combox wiring extended. My 2009 had both the needed mulf and tcu wires on the front side of the component stack. My friends 2011 had tcu facing front and mulf facing rear. 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.

USB in the glovebox has nothing to do with a combox. That USB hooks to the cic to update maps and upload music to the hard drive. USB in the arm rest connects to the MULF or combox in the hatch. That is where a tune2air would need to hook up. If you don't have an armrest usb don't worry. It is not needed as music streams over bluetooth once you add a combox.

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