A local car dealer contracted us to install a bluetooth kit today in a 2007 Audi A4. This is not an easy vehicle to integrate a bluetooth kit to. The factory Bose Symphony stereo system is what makes it challenging. Not a problem for the team at WSS! We were able to seamlessly install a Parrot bluetooth kit in a way that looked like a dealer add-on! The system will mute the factory stereo when receiving a call, and the voice of the caller plays right through the factory speakers. This bluetooth system allows the end client to talk on his phone LEGALLY while driving with both hands on the wheel! If you are interested in an Audi A4 bluetooth upgrade or you would like to add bluetooth to any vehicle, give us a call or Contact Us for more information!
