Acura 2009 TSX 00X31-TL1-8001 - Manual (Page 112)

Navigation System 111
System Setup
Vehicle
From the SETUP screen ( Other ), say
or select Vehicle and the following
screen appears:
Off-road Tracking
With this ON , the system will provide
white off-road tracking dots
(“breadcrumbs”) on the
map screen
whenever you drive into an area where
the map does not show any roads. See
Map Screen Legend on page 19.
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, or the 80, 200, 400,
and 800 meter scales. Rotate the
Interface Dial knob to change the
scales if necessary.
NOTE:
To clear existing dots, turn this feature
off and exit SETUP. To re-enable this
feature, return to SETUP and turn it on
again.
Correct Vehicle Position
The system relies on satellites for
positioning information. Buildings,
tunnels, and other objects can block or
reflect 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.
