CDR23 with Bose intermitently goes silent

[swynn97]

I'm hoping someone can help me here. Every couple of weeks I turn on my CDR23 stereo with Bose premium package and hear no sound. The radio is on and shows the channel etc., except that there is no sound. Actually there is a very high pitched quiet sound, but no music etc. If I turn off the car for perhaps > 5 minutes the radio comes back.

Anybody got any ideas? It's like the systems doesn't 'boot' up properly and the car needs to be turned off fully to recover. A quick cycle of the ignition doesn't fix this, but > 5 mins does.

Oh, and this is a US 2004 996 C2 Cab

thanks,

Simon

The few of these that I have heard about turned out to be a bad amp.

I had a similar situation in an 04 Boxster S, they pretty well admitted that there was a problem with some units and replaced it under warranty, it was done about a year ago this time and it hasn't malfunctioned since.

This has happened to me a few times. I pulled the fuses for the Accessory and Radio to inspect them. They were fine so I plugged them back in. It fixed the problem right away for me. This was in an '03 Boxster.

Only happened once, and that was after I replaced the battery and alternator. Only the word Porsche came up on the radio. I turned off the ignition, turned it back on the radio must have rebooted. If your problem is consistent I agree that it's likely a problem with the amp. good luck....

Thanks for the replies here. btw I've also had the "radio just displays 'PORSCHE'" problem just once. I'll ask the dealer about this...

Had the same issues in a 03 996 Bose... Dealer replaced the AMP before, same issues. I am out of warranty now with the same issues. Only fix I have is to pull the Radio fuse, re insert it, and it works. I would imagine its a head unit problem, or a buggy firmware version on those CDR223s.. (bug).. if you are still in warranty try another headunit...
