I just installed an AUX input in my car. I used the Auxiliary Input Retrofit Kit from ECS Tuning, BMW #65120153502, ECS Part# ES#180582 . The AUX input for the Z4 has only three pins which are installed in the 12-pin connector in the BLACK plug, not the 12-pin connector for the iPod adapter which is in a WHITE plug.

If you are looking at the back of the radio harness, the black plug (with a black 12-pin connector, Nav and Bluetooth) is in the lower right corner, the white plug (with a black 12-pin connector, iPod adapter) is in the lower left corner. If you don't have Nav and Bluetooth, then the lower right socket may be blank.

This kit includes the 12-pin connector as well as the black plug which plugs into the back of the radio harness. If you have Nav and Bluetooth, you have to remove either the 3 pins from the 12-pin connector in the kit or the existing 2 pins from the existing 12-pin connector and combine them. This kit includes a stereo mini plug on a cheap metal bracket which can be removed.

I should have bought the AUX input for the Mini as detailed in this post, which details the installation along with pictures: http://www.zpost.com/forums/showpost...80&postcount=5. It's about half the cost and appears to be the exact same thing. I've also attached a JPEG scan of a page that shows the pin outs from the installation instruction of a different OEM Aux Input Kit.

I also bought the Auxiliary Input Socket from ECS Tuning, BMW #84109237655, ECS Part# ES#2207518 to fill the hole in the under radio panel that I bought so I could use it to install a Homelink garage door opener. (The panel is no longer available without the AUX input jack hole already in it.) This takes an odd-shaped 4-pin plug in the back as below. Anyone know what the part number is for this four-pin plug?
