There are two different types of roads in the map
database, they are:
• Fully attributed roads allow for a destination to
be set and turn-by-turn guidance to be
provided to the exact location of the address.
• In Process Data (IPD) roads contain only
street name and address information.
Other information such as turn restrictions and
direction of travel is not included for these
IPD roads. Therefore, turn-by-turn guidance
cannot be provided to the exact address.
When trips are planned that include an IPD
destination, turn-by-turn guidance will be
provided on the fully attributed roads closest
to the destination.
When nearing the end of the highlighted route,
the system will state “Enroute to your
destination, some roads contain incomplete
data. Turn guidance will not be provided in this
area.” As you reach the end of the highlighted
route, the system will state “Turn guidance
will not be provided in this area. Please
use the direction arrow and distance indicator
to proceed to your destination.” You should
refer to the direction and distance information
in the lower center area of the screen to
navigate to the destination or refer to the
information in the waypoint box for a waypoint.
A purple highlighted route will appear on the
IPD roads. This is only a suggested route due
to the lack of traffic restriction information
on the IPD roads.
Special attention should be paid to the existing
traffic conditions, such as one-way streets
and prohibited turns.
Always follow the existing traffic restrictions.
Once your vehicle is near your destination, the
system will state “You’ve arrived at your
destination, ending route guidance.”
Traveling Across Regions
If you plan a trip that exceeds 5,000 miles
(8 046 km) in straight line distance from the
vehicle’s current position, you will receive a
message stating Destination/waypoint exceeds
maximum distance. To avoid this, plan your trip in
smaller segments. Select a closer destination
that you would like to travel through on your way
to your final destination.
