I just aquired an 07 A4 Quattro AWD. My first Audi. Does anyone know if it’s possible to connect my iPhone so I can play music through my factory stereo!speakers? I found a cable in the car with an charging end for an iPhone 4 but I can’t tell where it goes! Up behind the glove box, not into the glove box. There are no ports in the glove compartment which tells me I don’t have the iPhone package I guess? I really don’t want to replace the original stereo. Any thoughts, suggestions welcome.
