Hi, We have just bought our first Audi and its a Q7 we are very happy with it. It is a 2008 s line model, was the s line line not standard bluetooth? as the screen says "phone not installed". I have been reading up on it and alot of people say it could be the software is corrupt or out of date. Where do I get the software? and how do i install it to the car, Would I have to take the car to Audi to get this done? thanks
