This is not a probability of success.

I have PCM with original discs which works fine (surprising how few road changes there have been in the last 6 years).

I am in the North West and would be happy to let you try using my discs - at least then you'd know if it was a hardware or software problem.

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 guys, been lurking around the forums for a while now, but its now time to say hello and ask a question i have just bought a 2002 996 Carrera 4 with PCM1 16 bit version, everything works except the sat nav part, i get a cd read error every time i try to switch to it, i have pressed the button on the A/C screen to see which version of the operating system i have but it has nothing stored, it just has _ _ _ _ _ on display under the writing ( where i would assume it should have PONA628D or something similar) Has anyone had anything similar and if so how did you fix it? Do you think the updated discs and the vauxhall discs will fix it? Sorry for so many questions on my second post kev

where abouts are you? I have PCM with original discs which works fine (surprising how few road changes there have been in the last 6 years). I am in the North West and would be happy to let you try using my discs - at least then you'd know if it was a hardware or software problem.
