Enhancing GPS Performance
Sometimes the GPS feature is unable to complete a location calculation successfully. You hear an audible tone
indicating that your radio cannot see the satellites.
The GPS feature works best where there is nothing between your radio and a large amount of open sky. To maximize
the ability of your radio to determine a location fix, avoid closed space, tall buildings, and foliage. If possible, do not
use GPS in underground parking lots, tunnels, under bridges, and close to high buildings.
