Problem
The vehicle position icon on the map "lags" a short distance
behind, especially when I arrive at an intersection. Is there
anything wrong?
While I drive, my screen shows white dots ("breadcrumbs")
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?
My elevation (shown when I display the current position)
seems to fluctuate even though my elevation has not changed.
My elevation is missing on the "current position" screen.
Why?
No. When at an intersection, the system is unaware of the width of the
intersecting road. Large differences in vehicle position can indicate a
temporary loss of the GPS signal. See GPS Reception Issues on page 121.
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 70 and 112.
Go to "Vehicle" in the SETUP screen (Other), and set Off-road
Tracking to OFF, then return to the map. See page 112.
When you "draw" your area to avoid, make sure to select sections of roads
that include at least one intersection. See page 106.
The system calculates the bull's-eye location based on the street address
range allocated for that street. See Destination Icon on page 63 for an
example.
This is normal and due to errors in satellite position. The elevation can vary
+/- 100 feet. See System Limitations on page 121.
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.
