Amplifier

[vitaman]

For the last 2 weeks sound has been an iffy thing. Sometimes the amp powers radio, Satellite, CD etc. Sometimes dead silence. No rhyme. No reason.
Dealer says the amp has a glitch. They have to get one from Germany so it could take a few weeks. Anyone else had this problem?
As an aside, for those of us that just have one car, it is a revelation to climb back in the X5M after a few days in a 328. An aside on an aside, it's interesting to see which technology has become ubiquitous and which has not. The 328 has volume controls on the steering wheel but a radio circa 1993 and no Iphone integration.
