Hi all, I recently bought the BMW auxiliary audio input and tried to install it into my 2002 X5 3.0i (non-nav, non-DSP, non-multiCD). I can not get the aux to work. I plugged everything in according to the instructions given and your website. I press the mode button but all I get is radio and CD. Any help would be deeply appreciated.

FYI - I installed the item without unplugging the battery or fuses
