Map quality
The database vendor has verifi ed these streets.
Information like turn restrictions, average speed, and
whether it is a one-way street have been gathered and used
when creating your route to a destination.
These streets have not been verifi ed by the database
vendor. The system does not contain information on one-
way streets, turn restrictions, or the road’s average speed.
They are shown on the map for reference and may have
errors in map location, naming, and address range.
Routing
differences
While driving to your destination, the displayed route line
is solid blue. The system provides voice and map guidance
to your destination.
Your route line is either a purple dotted “vector line,” or
a dashed pink/blue line. For information on selecting this
option, and the routing differences, see Unverifi ed Area
Routing on page 108 .
Cautions
There are no pop-up boxes urging extra caution during
a route. However, because roads constantly change, you
are urged to use common sense, and always obey posted
traffi c restrictions.
Regardless of whether the user chooses route guidance,
there are cautionary screens before and during the route
urging the user to be extra cautious, and obey all traffi c
restrictions. See Unverifi ed Area Routing on page 108 .
Guidance
voice
Voice guidance issues instructions such as “In a half-mile,
make a right turn.”
The phrase “if possible” is added to each guidance
instruction. For example: “In a half-mile, make a right
turn, if possible.”
Time and
distance
“to go”
The time and distance “to go,” displayed while en route to
a destination, is based on the average speed and distance
for the roads used for your route.
