I’m a new owner of a 2006 Cayenne S Titanium Edition. I bought a new 2015 GPS DVD from Clima repair for a great price. I didn’t need to update the firmware, as the DVD loaded up after a few minutes. However, there doesn’t seem to be much difference with the 2015 compared to the 2006. I mean there are restaurants and new streets in my town built between 2006 and 2015 that are not on the map. Did I get a bootleg DVD or is the Porsche Source map just that bad?
