Diagnostic System Diagram
23-111
This diagram below shows and over view of the navigation diagnostic features starting at the center and working
outward in layers. The diagram starts with Key on. From any of the navigation Map or Menu screens, press and
simultaneously hold the keys Menu, MAP/GUIDE, and Cancel.
Finally, the diagram shows the available diagnostic menu choices, starting at the bottom left, and moving clockwise.
In most cases, do not clear or change settings in any diagnostic screen unless instructed to do so in the explanation, or
by the factory. If the factory asks you to insert a PCMCIA memory card into the PC card Slot, then the features specified
on the diagram with PC card are available.(cont’d)
