REPAIR PROCEDURE

UPDATE NAV SOFTWARE TO LATEST CONFIGURATION

CAUTION: “HLDF CAN BOOTLOADER…” recovery is possible using the Multi-Media Module
(MMM)/Navigation Unit provided that the recovery /software update disc YIA500010 is
available. The ” HLDF CAN BOOTLOADER Waiting to Start Download ” display MUST be
present for this procedure to be performed.

NOTE: Ensure that the screen is displaying ‘HLDF CAN BOOTLOADER Waiting to Start
Download’ only (the text on the screen may appear faint).

1.
If the NAV screen does not display the “BOOTLOADER”
message, DISCONTINUE this procedure.
2.
If the NAV screen displays the “BOOTLOADER”
