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.

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.
CD CHANGERS STOP WORKING FIRST THEN LOSS COMPLETE VOLUME
My cd changer and navigation system are not being detected.
At times the CD changer reports a error of "no cartridge" and it cannot load CD. Other times it works fine.
no radio volume or cd changer connection
command , cd , radio, navigation stop working
i am getting no sound to the speakers, the radio or CD player is working but no sound, the NAV works but no sound
COMMAND screen flashes on and off, radio goes on and off all by itself, no way to turn it on or off.
Looks like it needs a re-boot, but there are no directions on how to do it.
Tried different ignition keys-no effect.
Replaced an alternator just a few weeks ago.
The CD changer went out about 3-months ago. the radio would not turn on at the time the CD changer was going out.
I am starting to notice that the TeleAid is getting a lot slower. My car is now 13 years old and I wonder if the analog TeleAid Lifetime Warranty that I paid for is being dismantled.
Command unit and navigation system failure
Gps, radio works but no volume - nothing comes out of speakers. Cd changer is not recognized. Still trying to fix. pls help.
My unit would turn off and on, and I reported the problem with my first A service. They could not get it to duplicate. I again reported the problem and was told there was a recall on the instruments. The instruments were fine, the unit still turned off and on at will.
The problem was diagnosed when warranty expired.
Just Quit working. No warning . Just went.
screen keeps rebooting, mercedes says its audio command unit and asking $4500, yikes!!!!
