A couple of weeks ago I upgraded my 2006 B7 from Symphony to RNS-E. I'm glad I did it and really like the sd card functions but have a couple of niggles that I'm sure can be sorted with a little help from the people in the know. The niggles are........... Loud hiss in the car whenever I get in it, this is even before you put the key in the ignition The Gala system seems very sensitive no matter what setting you choose - even off When you start the car the music comes on fairly loud, even if you left it turned way down. The car is equiped with Bose if that makes a difference. I used an adaptor loom and didn't move an pins but have found the base and treble control now work much better so assume the fabled Bose wire is no longer connected. If anyone can suggest and hints ot tips I'd be very grateful.
