Magellan NAV 6500/NAV 6510 59
When using Map Shft, we recommend that you
physically go to a position that is clearly recogniz-
able on the paper chart, to serve as a basis for
performing the shift.
From any NAV screen, press Nxt Scrn until you are view
ing the Sat Status screen.
When the unit is computing position fixes, from the Sat
Status screen press the Map Shft softkey.
The Map Screen appears. When no Map Shft has been
set, the help bar indicates “No map shift set; press ENT to
set.”
Travel to a position you recognize with certainty on your
paper chart and use the ZOOM IN key to select a scale
level that closely matches the paper chart’s scale. Compare
this position on the paper chart with the boat position dis-
played on the receiver. The receiver’s boat icon may appear
to be far from your current position on the paper chart.
To set the bias, use the CURSOR KEY to move the cursor,
active at your current GPS position, to the position corre-
sponding to your current location on the paper chart. A
dotted line is traced from your current position to the cur-
sor. When you have finished placing the cursor, press EN-
TER.
As you travel, you can check to see that you have shifted the
boat’s position properly by comparing other points of refer-
ence on your paper chart with the corresponding points on
the electronic chart.
