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.
