These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

16 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

  • Rennlist: 1 discussions

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

2 acknowledgements have no verified action link; they do not establish a repair result.

Outcome without a verified action link

Usually is back to normal after the car is off a few hours or something.

POST 1 / ORIGINAL POSTEROriginal post

Yeah, I checked the Mute button first. My CDR23 powers up just fine in AM, FM and CD mode, but no sound. Any thoughts on the cause/solution? I'm gonna have to get a kazoo to entertain myself on long drives if this isn't an easy fix. I know I could update the sound system, but I'd prefer not to do so. Thanks

POST 2Original post

Check to see that the amp (should be in frunk) is powered up as well. If it is, check the wiring between the head unit and amp. If it isn't powering up check the fuse (it may be the same fuse as the head unit, which would be a moot point if the head unit powers up). If this is the case, there could be an internal fuse in the amp as well... Good luck

POST 3Original post

The best advice I have received about this issue is that you should always turn it off before you kill the engine. My advice is turn the car on, then turn the unit on and then off, then kill the engine, then cross your finger, then re-start the car, and turn the radio back on.

POST 4Original post

Mine does that sometimes. Usually is back to normal after the car is off a few hours or something.

POST 5 / ORIGINAL POSTEROriginal post

Good info and suggestions - thanks! I'll check fuses and also hope it simply works when I crank up the beast to drive home today. I've owned the car since 2007 and the sound system has worked fine up til today 9although the AM reception is a bit on the crappy side, which as I like the weather/traffic info on the drive to the office.

POST 6Original post

Do a search there are many threads about this. The general consensus is pull fuses D8 & D9 to reset the system.

POST 7Original post

POST 8Original post

It must be the day for this, as my car suffered the same symptoms, this morning.

POST 9Original post

Something is the airwaves? Mine went out as well. After sitting for an hour retried and it's back. I'm sure the problem will resurface.

POST 10 / ORIGINAL POSTEROriginal post

And we have a happy ending to this story; the stereo is back among the living. When I started the engine to drive home, I powered up the stereo and sure enough, lady gaga began singing to me. A quick station change and all was well again.

POST 12Original post

Must have been installing the new firmware after downloading it OTA. Only reasonable explanation.

POST 13Original post

"Although the AM reception is a bit on the crappy side" Are you sure it was the reception? I always thought AM radio was just crappy in general
