Navigation System Diagnostic Mode
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.
  • 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, and settings. If selected, a popup box is displayed asking if you want to clear the memory. If so, select ‘‘Yes''.
