In simulator mode, the Initialize GPS command makes the unit operate as if it is sitting someplace other than its actual location. So you and your unit could be located in Kansas City, but practice navigating in the ocean off Islamorada, Florida.

NOTE:

Remember: if you want to run a simulation in a place other than your current location, you first must Initialize the GPS, then turn on the GPS Simulator.

1.Press MENUMENU↓ to GPS SETUPENTENT.

2.A message appears, telling you to move the cursor near the desired location and press ENT. When the message automatically clears, follow the message instructions.
