I have a 2001 C4 that recently had a dead battery. When that occurs, after the battery is recharged, one must input the code number for the Porsche integrated radio and GPS system, which in the past unlocked the entire system. This time it unlocked everything but the factory GPS System, which now asks for me to input a code number for the GPS only. The system code number does not work for the GPS. I have the original plastic card that gives the code number for the entire system, and have never had a separate card that gives a GPS unlock code. A nearby Porsche service manager told me that the only way I will get the GPS unlock code from Porsche of America is to have the Agency remove the entire system from the dash and call in to Porsche of America a serial number off of the back end of the integrated system and then they must reinstall the entire system. Any one have a better way of getting the unlock code for the GPS system. That is a lot of labor just to get a serial number. Cicerosecundus

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.

my dealer gave me the PCM code when I gave them my VIN. Try another dealer.... give them proof it is your car.
I have the PCM Code. But, now that code does not work for the GPS System that has its own code separate from the PCM. Cicerosecundus

Can you explain further?? PCM is the nav/radio
There is a set of 13-digit alphanumeric codes that go with that VIN as delivered by PCNA. They have all that information at Atlanta. It's an email away from the dealer. It's my belief that they owe that information to you or they are in violation of the Federal law that allows you to maintain a car outside the authorized car manufacturer circles. I happen to have all my codes--and have retained them just in case the nonvolatile memory loses them.
