I guess I'm in a habit of resurrecting old threads recently, but I've bought a cable but I'm not seeing any AUX on my CD53 unit.
Car is built in November of 2001 and contains a BMW Business CD unit with MODE button.
In their ad it says: “This cable will enable AUX mode on your August 2002 or later Business CD head-unit.", which might be explaining the situation.
I've read that some of the cables require 100kOhm capacitor and 0,22microFarads resistors.
Looking for some help in resolving this problem. Appreciate any replies or hints how to fix it.

One side note. I think some time ago I've might have seen AUX label appear when selecting MODE. However I haven't seen it for some time now and I'm not getting AUX option now.
I may be wrong, but I think I have the same region 320 as you. Aux didn't work for me either. My other option was to go down a route that involved messing with the CD changer and adding some adapters back there (in the boot space).
