Navigation System 103

System Setup

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 68.

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.

2. Select Correct Vehicle Position,

and the system will display a map

adjustment 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:

1 2 ... 99 100 101 102 103 104 105 106 107 108 109 ... 174 175
