These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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 all, I have just brought a 2003 reg C4S and am looking at replacing the PCM head unit. Any recommendations as to the best unit with all the toys on. The latest Pioneer unit seems to have everything? Will I have to replace anything else? I understand the MOST system on these cars can be an issue? How do I know if I have it? Many thanks Rhys Williams

POST 2Original post

Take a look at Dynavin: http://www.dynavin.com/index.php Don't know if they have a version for your model yet but the one's they do for PCM 2.1 onwards are MOST/Bose compatible.

POST 3 / ORIGINAL POSTEROriginal post

Thanks Geoff, I will take a look.

This is a source reference. Confirm exact model applicability in the original material.
