System Diagnostic Mode: Version

WARNING: This page is about a different car, the 2008 Acura TSX, 2007 Acura TSX, and 2006 Acura TSX. However, it is still accessible from the selected car via links, so may be relevant.

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.

Program Flash is the version of the navigation program in memory.
Program Disc is the version of the program on the DVD.
The Values "IPL", "APL", "DBOOT", and "System uCom" are for factory use.
The value for "Models" should begin with the letters "SECX", and indicates that the navigation unit is for a TSX. If any other letters appear after "Models", then verify the part number on the underside of the navigation unit, and replace the navigation unit if necessary.
"Download" should never be touched unless instructed by the factory. Touching download overwrites the navigation software version in memory, with the software version on the DVD.

NOTE: If any model number other than SECX is displayed, replace the navigation unit with the correct part. The model code tells the navigation unit what software to load off the DVD.
