Hi All! As you can all see, Im quite new here and an Audi virgin. I have today just bought a 2007 S3. The question is how easy is it to fit the Audi Sat Nav system and Audi Multimedia Interface? I have seen units for sale on ebay. My S3 does not have an Aux-in slot (that I can see?!!) so I want to be able to control my ipod through the system and make it compatiable with the Bose speakers I have. Can you also make these Sat Nav Units play DVDs and receive TV? I also have the telephone prep in the armrest. Does anybody know if this works with Iphones? Is it also possible to fit a 2011 model S3 headlights with LED lights to a 2007 model and how easy is this to do? Thanks in Advance!
