Version This screen displays the current version of the program, and allows the loading of a new version of the program either from a CD/DVD or from a PC card. The D-Ram Program version should always be greater than or equal to the Disc Program version. The mapped database version is the date of the database on the DVD.
The Model code is 20H, and is for factory use only. This code is stored on a chip in the navigation unit. Therefore, every model has a unique part number for the navigation unit.
NOTE: If any model number other than 20H is displayed, replace the navigation unit with the correct part. The model code tells the navigation unit what software to load off the DVD.
Do not use DISC LOAD or Card LOAD, unless instructed to do so by the factory.
