Global Positioning System (GPS) Limitations

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2014 Honda Ridgeline, 2013 Honda Ridgeline, 2012 Honda Ridgeline, 2011 Honda Ridgeline, and 2010 Honda Ridgeline. However, it is still accessible from the selected car via links, so may be relevant.

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

For the first 5 to 10 minutes after reconnecting the battery (This can take as long as 45 minutes).
When the satellite signals are blocked by tall buildings, mountains, tunnels, large trees, large trucks, or being inside parking structures.
When the GPS antenna is blocked by metallic window tinting or by an object placed above it in the vehicle. The GPS antenna requires a clear unobstructed view of the sky.
When the satellite signals are blocked by the operation of some electronic aftermarket accessories including, but not limited, to non-OEM in-dash entertainment units (radio, CD players/changers, radar detectors, and theft recovery systems), and cell phones placed near the navigation system.

The accuracy of the GPS is reduced during these instances:

Metallic window tinting above the GPS antenna
When only three or less satellite signals are received (Four satellite signals are required for accurate positioning).
When driving near high tension power lines.
When the satellite control centers are experiencing problems.
