AUX in The W221
Hi, i've recently bought a S350 and strangely i cannot find the aux port anywhere. I do have an aux audio setting in the COMAND, but there is no port! The only aux port i found was in the back theatre system but that is all.

That's probably all you'll get. Run an RCA to stereo 3.5mm cable to wherever your device will be. Or a Bluetooth receiver so you can stream BT audio. Most 07-09 didn't get Aux at all. The Miccus BluBridge works well. It'll need power from a USB charger in a 12v receptical. (There's a battery but to keep it powered without pulling it out to charge it it needs a source in the car.)

Sorry. On the 2011 you need the MMI cable specific to the 221. It plugs into the glove box, upper right, into a rectangular receptacle that looks like a wide USB port.
The cable splits off into a male 30 pin IPod cable and an aux cable with a female 3.5mm aux jack. Most of us used a Tune2Air Bluetooth adapter that attaches to the iPod cable.
