Select Street
Move to <Street> and press ENTER. Select as described for select
City.
Once a Street has been selected it is then possible to move to <Start
Guide>.
When <Start guide> is selected, the system begins calculating the
route and distance to the destination (during this time, a yellow
symbol is shown at the top of the SCREEN). If a detour is made from
the planned route during the trip, the system automatically calculates
a new route.
If neither a street number or an intersecting street is specified the
system guides to the middle of the street chosen.
It is also possible to search for street addresses throughout the
State without specifying a particular City.
Street addresses are not stored in the system for some small
towns. The town centre, however, can always be specified as the
destination.
