System Limitations
GPS System
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 the sky. 
The GPS antenna is located in the 
dashboard. The signal reception can easily 
be interrupted or interfered with by the 
following:
• Metallic window tint on the front or 
side windows
• 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
• Audio electronic devices mounted near
the navigation unit
• Trees, tall buildings, freeway
overpasses, tunnels, or overhead 
electrical power wires
The GPS is operated by the U.S. 
Department of Defense. For security 
reasons, there are certain inaccuracies built 
into the GPS for which the navigation 
system must constantly compensate. This 
can cause occasional positioning errors of 
up to several hundred feet.
Address Calculation
The destination icon shows only the 
approximate location of a destination 
address. This occurs if the number of 
possible addresses is different from the 
number of actual addresses on a block. For 
example, the address 1425 on a 1400 
block with 100 possible addresses 
(because it is followed by the 1500 block) 
will be shown a quarter of the way down 
the block by the system. If there are only 
25 actual addresses on the block, the 
actual location of address 1425 would be 
at the end of the block.
Database
The digitized map database reflects 
conditions as they existed at various points 
in time before production. Accordingly, 
your database may contain inaccurate or 
incomplete data or information due to the 
passage of time, road construction, 
changing conditions, or other causes.
For example, some places/landmarks may 
be missing when you search the database 
because the name was misspelled, the 
place was improperly categorized, or a 
place/landmark is not yet in the database. 
This is also true for police stations, 
hospitals, and other public institutions. Do 
not rely on the navigation system if you 
need law enforcement or hospital services. 
Always check with local information 
sources.
