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 ho spital 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 th e 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, ch anging 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.
