If you are the owner of a Porsche that was purchased with a navigation system pre-installed in the dash, it is important to understand the process for updating the system when new maps or information become available. A navigation system uses the vehicle's location on a map via it's longitude and latitude to guide the driver and navigate to some given point of interest. Navigation systems also make it simple to find different types of locations that are nearby including gas stations, restaurants and more. When your maps are out of date, it can result in wrong directions or "destination not found" errors from the system.
Locate the Owner's Manual that came with the vehicle and search for the part number that is associated with the GPS system that is installed in the vehicle. Part numbers are usually located in the back of the manual.
Navigate to the Porsche website using a web browser and sign into your account by entering your user name and password into the corresponding text boxes at the top of the screen. Select "Navigation Update" from the list of available options on the next page.
Enter the part number into the corresponding text box on-screen. Continue by entering in your address and contact information so that Porsche can send the update disc to the proper location. Press "Send" to complete the ordering process.
Allow the GPS navigation update disc to arrive in the mail. Once it arrives, start the vehicle and insert the disc into the CD drive above the touch screen. The updates will automatically begin to download.
