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.

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/PHONE button. Rotate i to select
Setup and press u. Check that Volume is not set to
OFF .
2. Move y to select Other, rotate i to select Basic
Settings , and press u. 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 card in the glove box that
includes the 5-digit security code and serial number. You
should keep this card in a safe place outside your vehicle. If
you cannot find it, contact your dealer.

The vehicle position icon on the map “lags” a short

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. 61
How do I remove the white dots (“breadcrumbs”)
from my screen?
Press the INFO/PHONE button. Select Setup > Other > Vehicle , and set Off-road
Tracking to OFF , then return to the map. 2Off-road Tracking

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. 2 Avoiding Streets

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. 2GPS System
P. 224
My elevation is missing on the “current position”
screen.
The elevation is only displayed if the GPS antenna can receive signals from at least four
satellites. Try moving the vehicle into an open area. The elevation is also not displayed
if the calculated elevation is zero or below sea level.

Database
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.
