My OPC say they can sell me the 2007 maps for 350 quid, but from reading forums I think I can only use official Porsche CD’s up to 2004 on the PCM 1 system.

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.

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

POST 1 / ORIGINAL POSTEROriginal post

I know this topic has been debated a lot, and I’ve tried to figure out the answer from existing threads, but still not sure. Fair play to the people who’ve looked into this already. I have a MY 2002 C4 (Facelift 996, 3.6ltr) on a 51 plate I believe it has the 16bit version of PCM 1 (with the tape player) It came with a 2000-2 UK map and the PCM software version is PONA628D I get the consensus about separate sat navs being better than the PCM system, but I’d like to try and get my system half decent by getting a 2007 map for UK / Europe. My OPC say they can sell me the 2007 maps for 350 quid, but from reading forums I think I can only use official Porsche CD’s up to 2004 on the PCM 1 system. The alternative is to buy a 2007 CD from a company called Navishop in Germany, which I believe sell Vauxhall CD’s that work on 16bit PCM 1. These are about 160 Euro’s, but I’ve also read that you need a PCM software version of PONA642D for these to work, but I have no idea how to upgrade the s/w. Any advice on whether the Navishop disks will work is appreciated before I commit to buying them. Or, and I know it’s a bit cheeky to ask, but I’d be grateful if someone is prepared to burn me an ‘evaluation’ copy of their disk to try. Of course I’ll send a blank CD and return envelope.
