Display

This performs additional checks on the communication bus between the navi CPU and the display. In addition, the internal electronics and touch screen functionality are confirmed.

If the connection is NG, replace the navigation unit.
- Connection verifies internal communications.
- Version represents the software version for the display.




Radio
This diagnostic screen checks the internals of the radio (AM and FM) and CD player. If NG, replace the navigation unit.




Navi ECU
This screen looks for problem with the navigation unit. When this diagnostic is initiated, there is a delay of up to a minute while it runs.
- If "V-RAM" or "D-RAM" is NG, then replace the navigation unit.
- If "GPS" indicates "NG (ANT)", then check the entire GPS antenna wire from the navigation unit to the antenna. If the wire is crushed or damaged, try a known good antenna. If this diagnostic reads OK, then order a new GPS antenna. If the diagnostic still reads NG (ANT), then replace the navigation unit.
- "DVD ROM" represents the database version on the DVD. This information can also be found in Setup by selecting System Information.
- "Serial No." should be the same as the serial number found on the underside of the navigation unit. This number is needed to obtain the security code from the Interactive Network system.
- Mem Clear is for factory use, and should never be used unless instructed by the factory. Accidental selection will erase the customer's personal data, PINS, and settings. If selected, a popup box is displayed asking if you want to clear the memory. If so, select "Yes".

PC Card info




There is no PC Card in the PC slot, and the screen should say, "PC Card is not inserted".




If the factory provides a PC card and instructs you to insert a card, then the screen displays the Manufacturer, and Product Name as shown in the above screen. Touch the "FILES" button to see the contents of the card.




Hard Key

This diagnostic screen checks the status of each of the hard buttons surrounding the navigation display. When each hard button is pressed, the corresponding item on the screen should flash "blue". Touch the return key, or press and hold the joystick to exit.

NOTE: It is normal for the VOL(+,-) CH (+,-) and MODE button to be inactive.
