logging road).

that can block the GPS signal. Always perform Map matching (see MAP
MATCHING ) before proceeding with the troubleshooting.
1. Go into the Diagnostic mode, and do the Navi System Link diagnostic (see NAVI SYSTEM LINK ),
the Navi ECU diagnostic under "Unit Check" (see UNIT CHECK ), the Car Status check (see CAR

GPS DETAIL ), and the Yaw Rate check (see YAW RATE TUNING ).
Are all the tests OK?
