Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Discussions that performed work without a confirmed outcome: 1

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

I have the build spec from Porsche and it just says "Standard Radio", so I suspect someone has fitted a PCM afterwards, but with non of the modules (Phone CD changer, Nav).

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.

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

POST 1 / ORIGINAL POSTEROriginal post

Hi, I have 2 996 T's that have different radios fitted. (they were made about a week apart). One of them, on start up says "system error, CD, phone Nav no available" Thing is, car doesn't have these things fitted?! Question one is, was this an original fitted unit or has it been swapped with a unit that should have Nav, CD etc? question 2 is, how do I fix the error message? The radio and single CD work fine. I'll put a pic of each one up. Any help, advise on this much appreciated! Cheers Andy Download

POST 2Original post

Does PCM show in the options list in the maintenance booklet or under the front lid? If the PCM has been retrofitted without the devices shown, I suspect that it wasn't re-coded to suit. It should be a simple job to re-code the PCM to get rid of the error message. You need someone with a Porsche PST2 or PIWIS tester.

POST 3 / ORIGINAL POSTEROriginal post

Thanks for the advice. I have the build spec from Porsche and it just says "Standard Radio", so I suspect someone has fitted a PCM afterwards, but with non of the modules (Phone CD changer, Nav). Why? I have no idea!! Cheers Andy
