First off - thanks to Brian-BMW for the part numbers to make my own cable..

i built the cable with according to bmw manual with the 0.22uf capacitors and 300kOhm resistor. Plugged L/R into pins 3/4 and ground to pin 10.

I Turned on the car, held the [m] button and still can not get it to switch to Aux mode.

I vaguely remembering having Aux mode at some point... not sure though.

The radio *should* have AUX mode. It shows the manufacture date as 01-05.

Any suggestions??
thanks
