Ordering
process:

Depending on the current system version, PCM3.1 is updated either to system version 3.42 or 4.52
using the system software PCM3.1 Multimedia Update Disk.

ONLY for saving an additional navigation database:
If additional navigation data (e.g. America) is to be saved instead of the standard navigation data (e.g.
Europe = I-no. 610), the relevant additional equipment number (e.g. I-no. 615 = Navigation Software
North America) must be assigned to the vehicle.
You can get PCNA to assign this number by providing the following data:
•
•
•

Part number of retrofit kit
Vehicle identification number (VIN) of the vehicle to be converted
Order number used for ordering parts

IMPORTANT:
If you do not have the necessary data or if the data you have is incorrect, you CANNOT generate the
PCM navigation map material enabling code yourself using the supplied license key.
Once the order is confirmed, the additional equipment number can be found in the vehicle information
for the vehicle to be converted in the PIWIS information system in the Porsche Partner Network (PPN).
