Acura 2011 TL Navigation - Manual (Page 113)

System Setup
112 Navigation System
After you have traveled approximately
1/2 mile away from a mapped road, the
system will display a series of white
dots on the
map screen to show the
path you have traveled. This is provided
so you can follow the dots to backtrack
to the mapped road you originally left.
Tracking continues until you reach a
mapped road. See Off-road Tracking on
page 69 .
Tracking is shown only in the 1/20, 1/8,
1/4, and 1/2 mile scales, or the 80, 200,
400, and 800 meter scales. Rotate the
Interface Dial knob to change the
scale if necessary.
NOTE:
To clear existing dots, turn this feature
OFF and exit SET UP. To re-enable
this feature, return to SET UP and turn
it on again.
Correct Vehicle Position
The system relies on satellites for
positioning information. Buildings,
tunnels, and other objects can block
or refl ect these signals, requiring the
system to use “dead reckoning” to
determine your location and direction.
This can sometimes lead to small errors
in positioning, such as showing you on
an adjacent street.
NOTE:
Using this function to adjust vehicle
position is not recommended. When the
system acquires a GPS signal, it will
automatically place the vehicle in the
correct location.
If you choose to do this, follow these
steps:
1. Stop the vehicle.
2. Select Correct Vehicle Position ,
and the system will display a
Correct vehicle position screen.
3. Use the Interface Dial to move the
vehicle position arrowhead to the
correct location, and push in on the
Interface Dial . The display will
change to:
