I tried asking this question in the "ICE / SATNAV" forum, but haven't had any replies, thought i'd test the wealth of knowledge in the 8P forum as it's kind of car specific I'm trying to figure out if the Concert HU in my new S3 will have an Aux-in at the back of the unit. I know there is one in the center console but the reason I am asking is because I want to hard wire my iPhone car kit in and will look to pass a 3.5mm J2J cable behind the dash hopefully into the back of the HU. Can anybody tell me if there is an aux-in at the back of the HU? The car will also have the Ipod adapter fitted from factory just in case this makes a difference. Thanks in advance!!!
