    BM53 Aux option not working, Help!

    Hi all,

    I recently upgraded my BM53 with one that supports AUX and Satellite radio. My car is a 2002 525iT and does not have DSP or the 6 disk CD changer.

    Since I have factory navigation and my car has a 11/01 build date, I had to run the oem aux cable to the C connector on the radio in the back of the car.
    I have the correct pin connectors plugged into ports 3, 4, and 10.

    However, when I click mode on my Nav, AUX does not pop up. Need HELP!

    I’ve tried:
    Resetting the radio through the Nav
    Swapping between MK3/ MK4 Nav
    Unplugging battery
    Checking connectors

    Thanks!
    Andy
