My Sat, RES, audio has no sound and multi-disks have no power. I suspect some fuses burned out. I don't have the fuse charts for my GL450. Can one of you please scan one and post it here, hopefully stick it? This seems to be a very frequently asked question.

Thanks.

Just found djwright already summit a pdf of the Fuse Charts or Fuse Diagram or Fuse List in the above link. I used it and it is compatible with 2007 GL450.

With the list/Chart, I found a blown fuse for my Rear Entertainment Unit. I got a fuse tested and new fuses from auto store. Replaced the fuse and my RES works now. Also my radio has audio, got my SAT radio back and CD changer back. I didn't know this one fuse is connected to all these system. Now I know.

The fix cost me less than $5 and 2 days to research.

Hope this information will help others.

 

Timbertr,

I have the same issue!!!! No sound on audio, no RES power, no SAT. Which fuse (s) did u replace? I see the fuse chart but I can't figure it out

 

I know this is wayyyy late to the party, but I just cobbled together a guide with better pics & descriptions than MB. Sources are cited. Enjoy!

Thanks to Mercedes Medic and Start My Car for having solid info.

 

Great resource. Thanks for putting this together. W164 owners will.be happy to see this.

 

Very cool - thank you! Nice first post!

 

Just in case there could be a surprise ...

... my 2007 GL came from factory with fuse charts as part of the tool collection in the center of the donut spare tire. Maybe yours is still there.

 

That wast the first place I looked. I'm actually the 4th non-dealer owner/7th overall, so it was devoid of support or maintenance paperwork. Carfax was a godsend because you could see the upkeep detail. The good part for me in creating this was I became more familiar with the fuse system and block locations.
