+1 the Infiniti Bose systems are great. The Bose stereo in the Maserati quattroporte is awesome to. i also like the one in my c320 i like it a lot more then the hk stereo that was in my dads e320 cdi. This has been an argument on the forums forever wither the hk or the bose or that aftermarket system is best. i think if you like what you got then why argue on what is best.

Samaritrey, agree with you. I'm not an audiophile and have been acused (rightly) of being tone-deaf, so spending a lot of money on a car sound system doesn't make much sense for me. However, the sound in from my HK system is fine, now that there really is sound. If the sound goes out again, I'll start by removing and replacing the fuses. I noticed that one was 15 amps and one was 25 amps, so won't switch them, just remove and replace them in their original spots.

Thanks again for everybody for chiming in on this.

Over a couple years, horrible noises out of the speakers from time to time -and then all better! Now no sound at all. Radio looks like it is working (and dealer diagnosed it as fine - but says the amp is bad). I have purchased an amp from Adsit - a Mercedes parts seller - amp has same part number as original one. Hubby plugged it in and we still have no sound. Don't like paying dealer high time and labor costs - but maybe that is the only way?? Anyone have helpful info for me?

samaritrey

it could be a broken fiber cable.

Thanks, Trey! I am about to return the amp I bought and will be sent another. If that doesn't work, I will mention the broken fiber cable idea to the dealer. I appreciate your reply. It certainly seems like you have a lot of experience with foreign cars!

lol not really just read the forums a lot. And my passion is cars so i go and test drive them a lot and my family has had a lot of cool cars over the years. from my understanding it is not that hard to test the fiber cables just have never done it myself. GL

today my 05 c230 did this. no sound. shut the car down for a hour, turn it back on and it worked fine. anyway its about 95 out seems like maybe the amp is over heating. just an idea. radio was on for a few hours befor this happened.

Or it could have water contamination. Drove through any washes lately?

I have the same problem, tried to bend the fuse so it would get stick to the holder, it work for a while then it happens again , no sound! I think it's a sign that I have to change the HU: hopefully it works after I change the HU???

I forgot to mention that the car have 2 fuses: one for the radio #64(hood side) and one for the sound system which I do not have #26( door driver side).

ok my radio is totally out, no sound for the last few days, the head unit lights up cd changer works (hk). It has done this in the past but would hear sound a few minutes later after i shut everything off.
ive pull both the fuse under the hood and the side dash still nothing, i even unplugged the negative to the battery.
So my question is where is the amp located?
Oh and screw mercedes, this crap happens after the warranty goes out..

Happened to me - started getting infuriated because I had this issue once before where the CD changer would no longer register in my 01 slk - that issue was a bad ribbon in the changer, got lucky this time on my 05 c320 - the fuse trick worked. Car has been sitting out in 100 degree temps and I'm guessing the amp over heated - time to clear out the garage!!!

Fuse worked for me, yours sounds like the fiber optic cable.

07 c280 4matic, mods: command, voice control, bluetooth, climatronic LCD ac control. All oem. The no sound thing started recently and would magically disappear without any fuse changes, resets etc. One day the sound went out and did not return. First I checked everything, because of the mods, thinking fiber or individual modules themselves. No issues found. Plug the HK amp up and the sound returned. I thought cool just a reset after all, NOT. The sound went out after a couple of days. Well I went straight for the amp thinking maybe the fan on the unit was bad, causing a malfunction when trying to kick in. I removed the plate on the amp to check for any signs of a burned circuit before I layed out money for a new one. What I found is some of the soldered connections protruded through the board and possibly contacted the cover plate. There was one spot where there was a burned crystalized spot across connections which I knew would definately cause a short. Cleaned the board in that area, installed the amp, good to go. Didn't notice until the repair that the sat radio plays instantly before the command finishes it boot where as before there was a few second wait. It's a decent sound system. Maybe a design flaw which lead to so many replacements

Reviving this old thread. My wifes 203 just randomly quit having audio and lost communication with the CD changer. Remove the side panel on the dash and re-seated fuse 26(Audio Amp) and it started working again. Either loose connection at the fuse or it reset the amp, but either way, now its working.

Thank you sir, it worked for me!

Pulled Fuses #5 and #16 under the back seat and switched on the ignition. (2000 E320). Switched off and replaced Fuses #5 and #16. The radio is working again!

Dumb luck. I'll take it.

Thanks to all.
