Map
The Map destination entry method displays the last
location on the map, and the road preference.
Scroll across and touch the map at the location you
would like to set as your destination. Once you
have located the desired destination, touch the Enter
Destination screen button and then the OK screen
button. The route will then be calculated. You may begin
driving to start route guidance or you may touch the
Route screen button and then the Start screen button.
You may also zoom out to view the entire regional map.
See "Touch-Sensitive Screen Buttons" under Using
the Navigation System on page 2-2 for more information.
However, if you zoom out as much as possible and
scroll around the map, some parts of the map will
appear to be missing because they are not readable in
larger scales.
Previous Start Point
The Previous start point destination entry method allows
you to select the last start point as a destination.
Phone Number
The Phone Number destination entry method allows you
to search for a point of interest (POI) destination by
entering the POI phone number.
Enter the POI phone number on the numeric keypad
and touch the OK screen button. The destination
location will then be displayed. Most phone numbers for
POIs included in the DVD database can be entered
to locate a destination. Cellular phone numbers
and internal company phone numbers cannot be
entered to locate a destination.
