Is there really a big difference or improvement when moving to a DVD based navigation system such as what was offered in the 2005 Cayennes versus the 2004 version? Is it just that you have to 'load' more CD's when you go out of your region, whereas the DVD holds it all, or is the screen and/or output worse?



The DVD based version is not only faster but it also has a better screen, even if it looks completely the same.
There have been improvements, I would defintely prefer the DVD based version, unfortunately my car is a march 2004 build and I still have the CD version.
