The screen is showing white dots as I drive along.
How do I remove the white dots ("breadcrumbs")
from my screen?
A road that I selected to avoid is being used when
routing.
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.

Problem
These dots are called "breadcrumbs." These are displayed if Off-road Tracking is set
to ON and you drive more than 1/2 mile off mapped roads.
2 Off-road Tracking P. 62
Press the INFO button. Select Setup > Other > Vehicle, and set Off-road Tracking
to OFF, then return to the map.
2 Off-road Tracking P. 62
When you "draw" your area to avoid, make sure to select sections of roads that
include at least one intersection.
2 Avoiding Streets P. 117
This is normal. The elevation can vary ±100 feet due to GPS calculation errors.
2 GPS System P. 234
The elevation is only displayed if the GPS antenna can receive signals from at least four
satellites. Try moving the vehicle into an open area. The elevation is also not displayed
if the calculated elevation is zero or below sea level.
