Hi all - proud owner of a 'new to me' Cayenne 2004 model. Stupidly on purchase I did not check the satnav was working. The screen was knackered so wasn't a good picture - I have now swapped the front LCD out and voila we have a good clear screen.


Problem is everything works except the **** satnav - and that was one of my 'points' to convince the wife to buy it lol


Car came with a 2004 DVD that goes in the navigation unit under the seats. All I ever get though is the message "insert navigation DVD'


Ive checked the status and get satellites no problem - the main PCM unit also seems to know when I put a DVD in but it never gets any further


I also popped in the replacement PCM2.1 unit that actually had a higher version number of software 4.1 and so bought a 2015 DVD disc thinking it may need a newer DVD - same issue the message 'insert navigation DVD'


SO what could be my issue? Do you think its the navigation unit that's faulty - stopped reading DVD's??


Anyone know how to fix this? Anything I should check first?


Ive attached some photos if that helps anyone diagnose - help is VERY much appreciated

Hi Shanus,


Take a read of this and check your version numbers. If you need the upgrade discs I have all the files including the last Sat Nav upgrade dvd issued by Porsche a couple of years ago. All working on both my Cayenne and Carrera with PCM 2.1

I notice that TSB doesn’t mention Cayenne - so is it still valid for me?

Bear in mind the 2004 (MY2005?) will have a different starting point for the updates.  MY2006 will almost certainly be Level B, or possibly Level C, and yours is Level A.


 Also, not wishing to be pedantic, @angusc you might want to delete the attachment from your post.  @Loren is understandably concerned about Porsche copyright material being posted on the forum.
