CD Changer went bad 1st. It stopped working and then we began to have issues with the Main Head Unit in the dash. It turned on and off intermittently and finally went out completely. We have yet to get a proper diagnosis for this issue.

My cd changer and navigation system are not being detected.
Nav unit will not boot up. Mercedes dealer wants to replace the whole unit for $4500. I don't think its the unit but a computer glitch.
