Intersection
The Intersection destination entry method allows you to
select a destination by inputting the intersecting
roads you wish to travel to.
2-26
To enter a destination using this method, enter the
name of the street, but do not include name extensions
such as N. or Drive. For example, the street name
N. Civic Center Drive should be entered as
U
Civic Center. The system will search for an entry
exactly as you have entered it. If you did not include
a space between words where necessary, the system
may not be able to find the desired location. This
will bring up a list of streets with that name. Select the
desired street name from the list.
Now begin entering the second street name, and
choose the desired street name from the list. After both
street names in the intersection have been selected,
a list of cities containing the selected intersection
will appear. If there are several cities that contain that
specific intersection, you must specify a city. Select
the desired city from the list. 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.
