WARNING: This page is about a different car, the 2005 Acura TSX and 2004 Acura TSX. However, it is still accessible from the selected car via links, so may be relevant.
This screen diagnosis the navigation unit. When you initiate this diagnostic, the navigation unit may delay up to a minute while the diagnosis runs.
- "ROM (Application)", and "ROM (Loader)" are for factory use.
- 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. You can also find this information in Setup Screen 4 by touching "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 (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 client's settings, personal information, GPS orbital data, and anything else stored in memory.
