How do I make my porsche 2008 cayenne s navigation more accurate ? Is there an updated cd that can be loaded into the nav ?
The best advice I can give you for this is to ask the dealer. I'm sure there is an update available. Most GPS systems have annual updates. Find out the GPS manufacturer and go on their website if the dealer can't help you.
Updates only available with 2013 maps for over $300 and almost $200 to install the new bios at the dealership. About 1 hour wait and still 2 year old maps and POIs.
