Bose Amp TSB ITB05-026

[Raran1]

I just bought a one owner '06 M35X with 88K with the Premium pkg. After spending all weekend detailing it (damn proud of the results and sore) I got in this morning to go to work and the radio didn't work. I took it to my 'guy' thinking it would be a fuse and after he checked them (they were all good and had power) he found the TSB describing the problem exactly: no sound, no volume displayed and it would not even turn on. Has anyone out there had to replace the amp? If so how much and where can I find one? Thanks in advance for any responses. I really love this car and my son is now driving my A6!
