Well changing the radio head unit did not fix the problem. The dealer now has no idea what to do.

Misbe - On very rare occasions when I switch through the CD and to one of the radio settings it will mute. Every time this has happened all I had to do was cycle through again and my problem cleared immediately. So I don't have a big problem w/ this.

The problem I have is when I press dial on my phone, it actually dials out, but the stereo stays on the radio so I can neither hear or speak w/ my phone nor the stereo system. This used to happen about 1 in 10 times now it is about 4 in 5, and once it happens I have to keep dialing the number and after about 10 times the call will connect and my stereo will finally switch to phone mode.
