Hi - sounds like you are very knowledgeable on the Porsche 981 and PIWIS and conversions - etc.

I upgraded from CDR to PCM 3.1 and all went well with all function working - including maps in the Cluster. but I took my car to the dealer for some work and when it returned - the maps no longer displayed and the dealer told me that was not an option on my car 2013 and they would not fix.

I believe it is just a setting and I would love to know what setting I had to change to make them display - I have a PIWIS II.

can you help?
