Navigation System
System Diagnosis Mode (cont'd)
Navi ECU
This screen diagnoses the navigation unit. When this
diagnostic is initiated, there is a delay of up to a minute
while it runs.
NOTE: Do not try to end this diagnostic by pressing "OK"
or "Mem Clr" before it finishes, otherwise the system
will reboot.
• "ROM (Application)", and "ROM (Loader)" are for
factory use.
• If "V-RAM" or "D-RAM" is NG, then replace the navi-
gation 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 is Setup
Screen 4 by touching "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 (IN) system.
• The "Mem Clr" button is for factory use and should
not be used unless instructed by the factory.
Touching this button will erase the customer's set-
tings, personal information, GPS orbital data, and
anything else stored in memory.
