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.

Outcome without a verified action link
I've tried all the varied "solutions", but none of them have worked for me thus far.
Just bought a 2003 C2...the PPI indicated a problem w/ the radio. It turned on, but there was no audio. Dealership was to correct the problem.
After taking possession, radio worked for a brief period of time (maybe 20 minutes). Next time I turned it on, no audio (although display and buttons work).
Blown fuse? Something else?
Thanks!
There are two fuses - one in the fuse panel and one on the back of the radio chassis. You can check, verify and replace them. However, if they keep blowing, you probably have a short somewhere that needs to be sorted out.
Try one or both of these. These radios can be glitchy with weak batteries.
B)With car running, turn off radio. Turn off car. Lock car with key fob. Wait 5 minutes. Unlock car. Start car. Turn on radio.
C)disconnect negative battery terminal. Wait 5 minutes. Reconnect.
P.S. get a Bentley Manual.
You have the CDR-23? In 2003, Porsche moved to a fiber optic digital system using MOST. I've read there are very problematic, especially in the first years they were implemented. Many people end up having to take the car to Porsche for initialization (reset) with a PIWIS system.
I don't know what radio I have; after I posted the above thanks, I realized the manual provided is not for my radio.
It's a Porsche radio, and I assume it's original to the car.
Did you hear back from the place you bought it from.
Also, if you want to try another radio, I have a spare. Same model. I can ship it out to you. If so, PM me.
I have not heard back from the dealership...their post-sale customer service is lacking, to put it mildly.
Once I entered the radio model into the search, I found all the threads of other people having the same problem. I've tried all the varied "solutions", but none of them have worked for me thus far.
I really don't think it's a bad amp; I had audio immediately after taking possession, even though the radio was behaving oddly. It seems as though these radios are just extremely glitchy.
As I predicted, you have the CDR-23 MOST based radio. Any length of time on the forums and you'll realize that you are in good company (like alcoholic anonymous) in regards to the pains of this technology. You have the first run of MOST which is the CDR-23 or PCM2 ... therefore, you inherit "most" (no pun intended) of the problems too. Analog was a lot less problematic, but digital is the future and one way companies get you coming back to the dealerships. All the tricks on the forums really don't help much. Many of the people just take them back to Porsche for re-initialization and diagnostic checks. In many cases, you have to replace the head unit and amp. Other people that don't want to dump more money into an older factory system, choose to change their systems out and go with an aftermarket systems. That's usually the best route financially speaking IMHO.
My 03 would do the same thing if the battery was weak. I had to turn the radio off before I started the car or it would lose contact with the amp or ?. Once the car was running and the volts were up all worked fine.
