(a)Turn the ignition switch from OFF to ON, check that the malfunction disappea\
rs.
Standard: Malfunction disappears
HINT:
Even if the system works correctly, the following conditions may be seen: vehicle position mark turns, or the
map turns unwillingly. (It is because by turning the IG switch to ACC or ON during turning, \
navigation system
stores based on the angular speed). In that case, turn the IG switch from OFF to ACC\
or ON to return the
correct function.
