Why does the vehicle position icon on the map “lag” a
short distance behind my actual position, especially at
intersections?
This is normal. The navigation system is unaware of the
width of intersections. Large differences in vehicle position
can indicate a temporary loss of the GPS signal.
Why does the “time to destination” display sometimes
increase even though I am getting closer to my
destination?
The “time to destination” is based on the posted road
speed signs and your actual road speed to give you a
better estimate of arrival time.
Why does my clock frequently change the time forward
and backward by one hour?
The clock setting is automatically updated based on your
GPS location. If you normally drive between two time
zones, the clock may keep adjusting the time. You can
turn this feature off.

Clock Adjustment P. 47
How do I specify a destination when an entered city or
street could not be found?
Try entering the street first. Some cities are lumped in with
a major metro area. In rural “unverified” areas or new
subdivisions, streets may be missing or only partially
numbered.
How do I turn on the navigation system voice guidance?
1. Press the INFO button. Select Setup. Check that
Volume is not set to Off.
2. Select Other, then Basic Settings. Set Voice
Recognition Tutor to On if you want the system to
provide confirmations and system prompts.
My battery was disconnected or went dead, and the
navigation system is asking for a code. Where do I find it?
Your vehicle comes with a label in the Owner’s Manual kit
that includes the system’s secu rity code and serial number.
You should keep this label in a safe place outside your
vehicle. If you cannot find it, contact your dealer.

Troubleshooting
The blue highlighted route and voice guidance
stopped or turned into a blue/pink dashed line before I
got to my destination.Your route has entered an unverified area.
2Unverified Area Routing P. 42
How do I stop the map from rotating as I drive along?Select the map orientation icon on the map screen, or say d “Display north-up” to
change the map orientation.
Sometimes, I cannot select between the North-up and
Heading-up map orientations.The Heading-up map orientation can only be shown in the lower scales (1/20 - 1 mile
scales).
2 Map Scale and Functions P. 95
The “time to destination” display sometimes increases
even though I am getting closer to my destination.If your speed reduces due to slower traffic, the navigation system updates the “time to
destination” based on your actual road speed 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.This is normal. The navigation system is un aware of the width of intersections. Large
differences in vehicle position can indicate a temporary loss of the GPS signal.

The screen is showing white dots as I drive along.These dots are called “breadcrumbs.” These are displayed if Off-road Tracking is set
to On and you drive more than 1/2 mile off mapped roads.
2Off-road Tracking P. 51
How do I remove the white dots (“breadcrumbs”)
from my screen?Press the INFO button. Select Setup > Other > Vehicle , and set Off-road Tracking
to Off , then return to the map.
2Off-road Tracking P. 51
A road that I selected to avoid is being used when
routing.When you “draw” your area to avoid, make sure to select sections of roads that
include at least one intersection.
2Avoiding Streets P. 102
My elevation (shown when I display the current
position) seems to fluctuate even though my elevation
has not changed.This is normal. The elevation can vary ±100 feet due to GPS calculation errors.

X XSystem Limitations XDatabase
Reference Information
In addition, the map database contains
verified and unverified areas. Unverified
streets may be missing from the map, in
the wrong location, or have an incorrect
name or address range. A message will
warn you if your route includes unverified
streets. Exercise additional caution when
driving in unve rified areas.
The database does not include, analyze,
process, 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
• Traffic facilities safety
• Special events •
Pavement characteristics or conditions
Every effort has been made to verify that
the database is accurate. The number of
inaccuracies you experience increases the
longer you go without obtaining an
updated map database.
