Also, depending on your current view of 
the sky and the position of the satellites, 
the elevation may be shown incorrectly.
You may also notice some delay of the 
vehicle position icon at intersections; 
this is normal.

The signals received from the GPS 
satellites are extremely weak (less than 
a millionth of the strength of a local FM 
station) and require an unobstructed 
view of sky. The signal can easily be 
interrupted or interfered with by the 
following:

• Aftermarket metallic window tint 

above or to the sides of the GPS 
antenna (located on the back of the 
navigation display)

• Cell phones, PDAs, or other 

electronic devices docked in a cradle 
or lying loose on the dashboard

• Remote starters or “hidden” vehicle 

tracking systems mounted near the 
navigation unit

• Other aftermarket audio electronic 

devices mounted near the navigation 
unit

• Trees, tall buildings, freeway 

overpasses, tunnels, or overhead 
electrical power wires

Although the system will direct you to 
your desired destination, it may not 
always generate what you consider to be 
the most direct route. Try changing the 
method of routing. See Changing the 
Route Preference on page

. You may 

also have Unverified Area Routing set 
to OFF. See Unverified Area Routing on 
page

Additionally, the mapping database 
contains verified and unverified maps. 
See Map Overview on page

Disclaimer

 screen will warn you if your 

route includes unverified streets.
Unverified streets may be missing from 
the map, in the wrong location, or have 
an incorrect name or address range. 
Exercise additional caution when 
driving in these unverified areas.

The destination icon shows the 
approximate location of the destination. 
This occurs because a city block can 
have as many as 100 possible addresses 
(for example, the 1400 block is followed 
by the 1500 block) Since most cities use 
only a portion of the 100 possible 
addresses (for example, in the 1400 
block, the addresses may only go up to 
1425 before the 1500 block starts), the 
address 1425 will be shown a quarter of 
the way down the block by the system 
instead of at the end of the block where 
the destination is actually located.

You may find that the system 
occasionally reboots. This is indicated 
by the display returning to the 

navigation system globe

 screen. A 

reboot can be caused by a number of 
things, such as extreme temperatures or 
shock from bumpy roads. It does not 
necessarily indicate a problem that 
requires service. If this happens 
frequently, please see your dealer.
