System Limitations
GPS
The signals received from 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 wind
ows
• Cellular phones, PDAs, or other electronic
d
evices docked in a cradle or lying loose
on the dashboard
• Remote starters or "hidden" vehicle
tracking system
s mounted near the
navigation unit
• Audio electronic devices mounted near
the nav
igation unit
• Trees, tall buildings, highway overpasses, tunnels, or overhead
electrical power
wires GPS is operated by the U.S. Department of
Defense
. For security reasons, there are
certain inaccuracies bu ilt into GPS for which
the navigation system must constantly
compensate. This can cause occasional
positioning errors of up to several hundred
feet (meters).
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 addr esses 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 st ations, hospitals, and
other public institutions. Do not rely on the
navigation system if you need law
enforcement or hospital services. Always
check with local in formation sources.
