Fuse schedule and locations 2008 S550

[Bill Philcox]

I bought a used 2008 S550, and the radio isn't working. The display is OK, but no audio whether the GPS, DVD/CD or AM/FM. I want to do a soft reboot, but I have to know where the fuses are, and which ones to pull. The fuse schedule and diagram was missing, and I didn't know it.
Does anyone have any ideas where to get the info I need? Anyone had had the same "no audio" problem?
Thanks

Thank you so much. I am trying to get the sound system to work, and not having the fuse locations would be a serious challenge. I appreciate your quick and useful reply.
After looking at the info on the fuses, how do I know which fuse is which? For example, which fuse is F38? I need to know how these fuses are identified, now that I know which ones I want to remove.
Sorry to be such a PIA, but I am working at a disadvantage by not knowing which fuse is which.

Harmon Khardon system? (look on speaker grills)

you need to spend £1000 to £1200 on a new amp - std fault on any HK system

numerous post about this recently and 3 failed attempts to repair in UK with BBA, but these guys allegedly can in Bulgaria

sounds like its a reflow issue on one of the chipsets, repaired there and back circa £350 is my guess

Have a look at this PDF diagram Bill. Its a bit clearer.

Scroll down to the attachments in Post #1 and download the 4th one down as a PDF file.

Its easy to follow then.
