Navi ECU
This screen looks for problems with the navigation unit. When you initiate this diagnosis, the navigation unit may delay up to a minute while the diagnosis 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 diagnosis reads OK, then replace the GPS antenna. If the diagnosis still reads NG (ANT), then replace the navigation unit.
- DVD ROM represents the database version on the DVD. You can also find this information in Setup Screen 4 by selecting System Information.
- Serial No. should be the same as the serial number found on the underside of the navigation unit. You need this number to obtain the security code from the Interactive Network (i N) system.
- Mem Clr 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 pop-up box appears asking if you want to clear the memory. If so, select Yes.
