Diagnosis Menu

The Diagnosis Menu screen has seven buttons. The top two buttons, LINE/DEALER and INSPECTION, have no function; they serve as functional titles for the buttons below them.

The buttons below LINE/DEALER are:
^ SYSTEM
^ DIAG MEMO
^ VEHICLE SIG

The buttons below INSPECTION are:
^ DISPLAY
^ NAVI

Each of the five buttons, when pressed, leads to a menu or set of submenus which may be used to perform various navigation self-test procedures.
