System Setup
Edit Waypoint Search Area
When driving en route to your
destination, you can select a temporary
destination waypoint (marked with a
small flag on the map) along your route
for gas, a restaurant, or other POI. When
you resume your trip from the waypoint,
the system continues the trip to your
original destination. To use this feature,
see Waypoints on page 64.
This Setup item allows you to select the
distance from your highlighted route
line (on either side of your route) that
the system will search for a waypoint.
From the Routing & Guidance screen,
select Edit for “Edit Waypoint Search
Area,” and then choose the desired
search distance for either “On
Freeways” or “On Surface Street.” The diagram below shows how the
system handles the search for “Places
Along the Rout
e” or “Places Around the
Destination” (see Waypoints on
page 64). For “Places Along the Route,” the
system looks in front of you within a
corridor width specified by your values
for “On Freeways” or “On Surface
Street.”
The system checks the upcoming area,
based on your input.
For “Places Around the Destination,”
the system searches outwards in a spiral
from the destination. In this case,
specific search values are not needed;
the matches are displayed in order of
distance from destination.
NOTE:
These settings do not affect the search
range used for the voice commands like
“Find nearest gas station” that are also
available when viewing the
map screen.

Database Limitations
You will find that some points of
interest (POI) may be missing when you
search the database. This can be caused
if at the time the database was gathered,
the name was misspelled, the place was
improperly categorized, or the POI
change is not yet in the database. This
means you may not find places listed
that you know exist. This is also true for
police agencies and hospitals. In
outlying areas, facilities listed may not
be the closest. Always check with local
information sources if you need law
enforcement or hospital services.
Every effort has been made to verify
that the system’s database was accurate
at the time it was created. However,
businesses do close or relocate, and new
businesses start in the old locations. For
this reason, you may occasionally find
inaccurate information when you select
and drive to a point of interest (for
example, a restaurant is now a jewelry
store). The number of these inaccuracies
increases the longer you go without an
update. The digitized map database reflects
conditions as they existed at various
points in time before production.
Accordingly, your
DVD may contain
inaccurate or incomplete data or
information due to the passage of time,
road construction, changing conditions,
or other causes.
Due to ongoing software and database
improvements, navigation disc versions
may change in the middle of a
production year. The version shipped
with your vehicle was the most recent
available at the time of production and
is considered standard equipment for
that vehicle. There is no free program to
retrofit early production vehicles with
the latest disc. For DVD ordering
information, see page 105. In addition, this database does not
include, analyze, proc
ess, consider, or
reflect any of the following categories
of information:
• Neighborhood quality or safety
• Population density
• Availability or proximity of law enforcement
• Emergency, rescue, medical, or other assistance
• Construction work, zones, or hazards
• Road and lane closures
• Legal restrictions (such as vehicular type, weight, load, height, and speed
restrictions)
• Road slope or grade
• Bridge height, width, weight, or other limits
• Road traffic, safety, or conditions
• Weather conditions
• Special events
• Pavement characteristics or conditions

Frequently Asked Questions
Guidance, Routing
Problem Solution
The navigation does not route me the same way I would go, or
the way some other mapping progr am displays. Why is this?The navigation system attempts to
generate the optimum route. See
Changing the Routing Method on page 47.
Why is the street I’m on not s hown on the map? It has been
here for more than a year. The mapping database is
constantly undergoing revision. See page 105 for
ways to obtain the latest de tailed coverage information.
The vehicle position icon is not following the road, and the
“GPS icon” text in the upper left hand corner of the screen is
white or missing. • The GPS antenna (located under th
e center of the dashboard) may be
blocked by personal items. For best reception, remove items from the
dashboard, such as radar detector s, cell phones, or loose articles.
• Metallic tinting or other aftermarke t devices can interfere with the GPS
reception. Please see your dealer. Also see System Limitations on
page 100.
I entered a destination, but th e blue highlighted route and
voice guidance stopped, or turned into a blue/pink dashed line
before I got to my dest ination. Why is this? Your route has entered
an unverified area. See Unverified Area Routing on
page 85.
The map rotates while I make turns. How can I stop this? Select the North-up map orientation by voice, or by touching the map
orientation icon on the map screen. See Map Orientation on page 56.
Sometimes, I cannot select between the North-up and
Heading-up map orienta tions. Why is this? The Heading-up map orient
ation can only be shown in the lower scales
(1/20 - 1 mile scales). See Map Scale on page 55.
While driving to my destinati on, the “time to go” display
sometimes increases, even though I am getting closer. The “Time to go” is based on actual
road speeds. However if your speed
slows down when you encounter slower traffic, the system updates the
“Time to go” based on your actual spee d to give you a better estimate of
arrival time.
The vehicle position icon on the map “lags” a short distance
behind, especially when I arrive at an intersection. Is there
anything wrong? No. When at an intersection, the syst
em is unaware of the width of the
intersecting road. Large differences in vehicle position can indicate a
temporary loss of the GPS signal. See GPS Reception Issues on page 100.
