Porsche PCM Systems - Versions And Software

[digjharper]

Apologies for asking a question which I am sure has been asked many times before, but can anybody advise on how to identify the various PCM systems?

I am a proud owner of an October 2003 Cayenne S (it was my choice and I love it) but I want to update the maps on the PCM system (CD based not DVD). I have had zero help from my local Porsche garage and they cannot offer me any update on the system but have sourced some other locations which will sell me updated software.

However, I have no wish to purchase new discs only to find they do not work. How can I identify idf it is a PCM version 1 or 2? and also if it needs any additional software to allow me to use updated discs?

I have sourced someone in Bulgaria who is selling 2008 disc sets for $50 - too good to be true?

I understand the way of telling which one you have is as follows,

PCM1 has casette
PCM2 has not.

Please correct me if I am wrong. I have ordered the 8 disc package from Eastern Europe and will advise once arrived and if it works.

By pressing the main and trip button that will tell you what version of software you have.

I am sure that PCM 1 has casette and PCM 2 has not.

Is it permissable to post links to a source who is selling these for a very cheap price?

Well I got my 8 discs delivered today from Romania.

Hower I am currently in the US and my wife is not very technically minded so I cannot confirm if they work. If they do then it will be well woth the $50 I paid for them.

Just to let you know that the discs are working first class and as are advertised. They actually came from Bulgaria and not Romania as I originally thought.

All 8 discs work fine.
