Hi, in the A3 I'll be picking up later this week there's only the Chorus casette player system. No changer and I don't think there's any BOSE in the car. It's a 1.6 SE, 2002. Could anyone recommend a decent HU that can connect to an iPod and control it through the HU (Also don't mind having an Aux 3.5mm socket), and ideally with Bluetooth to connect to my phone and take calls through it. I won't be putting an amp or sub in the car, just sticking with the usual speakers, but want something to play my iPod through. I read about VAG-COM devices can be ruined because something to do with the K-Line and the radio harness. Do I need to worry about that when trying to find a HU?
