Outside Temp. Cal.: 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 21H, and identifies the control unit as a MDX part. Do not substitute any other control units with other model codes.
Do not use DISC LOAD or Card LOAD, unless instructed to do so by the factory.
NOTE:
If any model number other than 21H is displayed, replace the navigation unit with the correct part. The model code tells the navigation unit what software to load off the DVD.
