Magellan NAV 6500/NAV 6510 61
Position coordinates on your receiver do not match the loca-
tion on your map.
Ẅ Make sure that your receiver is set up to use
the same datum as your map. The map da-
tum is generally shown in the map legend. See
Map Datum under Navigation Setup for in-
structions on selecting the map datum in your
receiver.
Position fix fluctuates
Ẅ Small changes in the position coordinates and
elevation are normal. They are caused by sev-
eral variables, including the geometric quality
of the fix and the effects of SA. Geometric
quality is a measurement of the probable ac-
curacy of a fix based on the position of the
satellites being used in relation to each other.
Unit does not recognize C-card installed
Ẅ Make sure the C-card is mounted all the way
into the C-card slot so it is locked in place.
ẅ Check the C-card contacts to make sure they
are clean. If dirt is collected on the gold con-
tacts, use a soft dry cloth to wipe the dirt away.
