2002 A6 replacement for Symphony II
I have recently purchased an Audi and now have a problem with the sound system. The unit will not turn on but the back light stays lit even with the key out and locked. I replaced the fuse, it acts exactly the same. Any ideas? If this turns into something crazy, I would rather just upgrade to DVD/NAV/ aftermarket replacement. Suggestions?? Jack 
Best I could find is koolertron QL-ADI756 Anyone have any experience with this?
