Global Positioning System (GPS) Limitations

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2004 Honda Odyssey, 2003 Honda Odyssey, 2002 Honda Odyssey, 2001 Honda Odyssey, and 2000 Honda Odyssey. However, it is still accessible from the selected car via links, so may be relevant.

The GPS cannot detect the vehicle's position during the following instances:

For the first 5 to 10 minutes after reconnecting the battery.
When the satellite signals are blocked by tall buildings, mountains, tunnels, large trees, or large trucks.
When the GPS antenna is blocked by something on the dashboard.
When there is no satellite signal output (signal output is sometimes stopped for satellite servicing).
When the satellite signals are blocked by the operation of some electronic after-market accessories.

The accuracy of GPS is reduced during these instances:

When only two satellite signals can be received (Three satellite signals are required for accurate positioning).
When the satellite control centers are experiencing problems.
When driving near high tension power lines.
