As above, I currently have the Concert II stereo in my A3. It also has factory fitted bluetooth installed, which has been working fine in terms of reiceving calls etc. Although I don't have the ability to look up contacts, which i'm sure if my headunit is supposed or not may be the case to do?
My question is if I upgrade to the RNS-E, will the factory fitted bluetooth continue to work seamlessly or is my current bluetooth set-up only functional with my Concert II headunit?
Many thanks in advance for the help.
