Stereo seems fine, but

2008 GL450, the radio on the dash appears fine, shows the radio stations, etc., but No Sound. It's totally silent. It is not asking for a code, like you'd expect if the battery was disconnected and re-connected. There is just silence. Anyone have any idea what to do? Many thanks and appreciation.

Did you verify the mute logo isnít displayed in the upper right corner of the screen? I had the same issue a few months back and somehow I had inadvertently pushed the mute button. I tried everything then I watched a video on YouTube that someone that had the same issue posted. Good luck.

Thanks James, I have tried turning on and off the Mute function, no sound. Pressed every button, tried everything, including the remote control; I inserted a music CD and it began to play, showing track number and seconds, but still no sound. Maybe there is a fuse for the amps? I will look in my owners manual for a map to the fuses and have a look...

A little more research and I read somewhere that the system has fiber optic cables that go bad, so I took the car to a car stereo specialty store and they told me the amps go bad, and that the amps are specific to the head unit and that both would need to be replaced. Obviously wanting to make a sale. What's odd is the VIN decoder says that my car has a CD changer but there is no changer in the car that I can find. Just the deck in the dash with a slot for Nav DVD and a slot for a music CD. So, a new head unit and new amp will cost over $1000. I may just wait a month or so and see what happens. Having just bought the car, other "needs" may pop up after a week or two. (Murphys Law)

The changer should be built into the head unit.

CD changer

The Cd changer is in the head unit.
The Cd slot is for single CDs and the DVD slot is for the navigation system.

Unfortunately, I am many miles from Tallahassee. I am currently near Seattle. Just had an earthquake at 2:50 this morning! Stereo still silent. Earthquake didn't fix it.

EDITED... Please accept my apologies!
Tony,
I read your other thread (July 3) for your 2008 GL450... Congratulations!
It seems that you have NTG2.0, which is the same one I've had on my previous 2006 SL500.

Generally speaking, MB amps are die hards and has internal electronic protection systems that can effectively prevents overloading; so nevermind wht stereo shops claim. If you check the used MB stereos on Ebay, more than half of them are sold by shops for known reaons.

Based on my 2010 GL550 (X164), and from the symptoms you listed I can tell that the plugs at the back of your head unit (on dash) has some loose connections of some sort. Please take the unit out and snap pictures of each an every plug to confirm that (1) they are on the correct locations (2) perfectly plugged (3) to confirm that the male fibre optic bus connector of 2-orange hard FOs are perfectly connected on their female plug on the head unit.

The main big connector has multiple plugs mounted on it, and any misplacement of these will result in no audio (and in my case, no one can hear me speaking on the phone bluetooth connections...misplaced the plug).

Now. you may ask, why the heck anyone goes there to plug/unplug things?
The answer is: It is possible due to the installation of VIM Modules (Video in Motion) which enables DVD playing and GPS change while driving. This module hooks up between the OEM harness and the head unit and it will involve fibre optic displacement.

There are UTube videos to teach you how to take the NTG unit out of the dash... It is extremely easy.
Bring back the requested conformations and we can discuss further
