Honda 00X31-SHJ-8200 Manuale Utente

Although your navigation system is one 
of the most highly sophisticated pieces 
of equipment you will find in a modern 
automobile, you may find during its use 
that it has certain limitations.

The system uses GPS signals to aid in 
determining its current location. The 
GPS is operated by the U.S.
Department of Defense. For security 
reasons, there are certain inaccuracies 
built into the GPS that the navigation 
system must constantly compensate for. 
This can cause occasional positioning 
errors of up to several hundred feet.

For example, in urban areas where 
streets are close together, this could 
cause the system to show that you are 
traveling on a street that parallels the 
street you are actually on. The system 
will, under most circumstances, correct 
itself while you drive.

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 the 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 under the 
dashboard)

• Cell phones, PDAs, or other 

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

• Radar detectors mounted 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 
Routing Method on page 48. You may 
also have Unverified Area Routing set 
to OFF. See Unverified Area Routing on 
page 86.

Additionally, the mapping database 
contains verified and unverified maps. 
See Map Overview on page 6. A 

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.
