Is there any aux inputs on a 2008 Audi a6 I'm going to get one tomorrow and at the dealership, I never checked online I came across a few places saying it does and it doesn't does anyone know if it does? or if I can add Bluetooth/aux so I can play my own music
The built in Bluetooth won't allow the playback of music/media - it doesn't have the appropriate BT profiles and will only connect for phone purposes. Audi didn't add that in until 2012-13, and yes it's extremely annoying!
If you've got the MMI 3G with the Audi Music Interface connector in the glovebox you should be able to get a Bluetooth adapter that connects to that port and in turn to the phone via BT (this is what I have in my RS5). This doesn't work for pre-09 cars that have the MMI 2G though IIRC so you'll want to check which variant you have before ordering any kit.
Not sure if it holds true for all adapters but at least for mine it's a "dumb" connection - mirroring the functionality of a plain AUX IN lead so you can't control playback or get track info etc this way so you still have to use the phone to select and play tracks.
