After a recent episode with a flat battery on an 04 986, I was pursuaded to use a portable battery booster through the cigarette lighter to allow me to pop the front bonnet.

During the boost phase the car alarm sounded and instictively i turned the ignition keys to silence it. Stupid, I know.

Long story short the car is now fine but dead CDR - it just doesnt power on at all. I've changed the fuses for radio & amp, plus the inline fuse to the rear of the head unit but no joy.

Just wondered if anyone had similar experiences / suggestions / knew of anyone who might attempt a diagnosis of the head unit ... ?

Failing that is there a cheap direct replacement unit anyone could suggest pls.?

Thanks.

Sounds like you have checked all of the usual issues with your unit. If you have no luck with repair, try this link CLICK HERE. There are a variety of used OEM and others on this eBay search at various prices.

Good luck!

The CDR 23 radio needs to have the PST2 hooked up to coordinate the radio internal code with the one in the instrument panel. This is usually a quick dealer fix. This radio does not have a code that can be reset by the owner. This situation occurs when you disconnect the battery or remove the radio and reinstall it. This is an anti-theft feature.

Interestingly, after having the fuses pulled for 4 or 5 weeks, yesterday the CDR23 burst into life when re-connected (until the ignition was next switched off).

This validates that the vehicle VIN code has been lost from the unit and requires re-programming via PST2 - to be discovered shortly ;-)
