on it. What do they mean?
How can I get rid of the white dots ("breadcrumbs") from my
screen?
A road that I selected to avoid is being used when routing.
What is wrong?
When I arrive at my destination, the bull's-eye is shown at a
different location on the street. Why?

seems to fluctuate even though my elevation has not changed.
My elevation is missing on the "current position" screen.
Why?
128 Navigation System
These are called "breadcrumbs." If you drive more than 1/2 mile from
mapped roads, the off-road tracking feature begins to function. See Off-road
Tracking on pages 61 and 92.
Go to "Vehicle" in the Setup screen (second), and set Off-road Tracking
to Off, then return to the map. See page 92.
When you "draw" your area to avoid, make sure to select sections of roads
that include at least one intersection. See page 89.
The system calculates the bull's-eye location based on the street address
range allocated for that street. See Destination Icon on page 56 for an
example.
This is normal and due to errors in satellite position. The elevation can vary
+/- 100 feet. See System Limitations on page 100.
If the GPS antenna cannot receive at least four satellites, the elevation is not
displayed. Try moving the vehicle into an open area. If the elevation is zero
or below sea level, the elevation is also not displayed.
