Aux option but no Aux input 03 E55?

[method]

I was playing around with the APS and noticed there is an aux button where you can select auxiliary in, but I can't find the input??? I Have looked in the glove box and no tiny hole exists where most have said it does. Is this something that you had to have as an added option when you bought the car? Is it possible to get one added in?

Yes It can be added ..remove the head unit and the glove box for the install

Use a Unibit to drill the hole on the side of the glove box
