Ok as titled. Im looking to change my head unit to something a bit more classy. The girlfriend has bought herself a nice brand new Audi A1 5door 2012 model and it is top class. My favourite thing about the car is her bluetooth system. when she steps into her car the bluetooth automatically connects to her phone and she is able to play songs from her phone via the unit and make calls etc. my question is what would the best single din unit be to get? Im not too bothered about having a big fancy screen or anything as my main purpose would be the bluetooth feature so i can link the phone, play the music and make a few calls whilst driving so the screen isnt important. obviously less expensive the better but still holding the quality. I've googled and asked mates advice but i always know you guys would have good advice also. cheers for looking!
