GPS Information
The GPS Information menu lets you test the GPS
device without using the WorldNav navigation
software. You need at least 4 satellites to lock into
position with accuracy. The blue bars will turn green
as the GPS obtains proper positioning information. If
this menu shows that you are not able to lock into
position, you can press the "Reset" (on the bottom
left of the menu). The system will try again from the
beginning to lock into position.

Screen Calibration
Occasionally you may need to recalibrate the touch
screen if you notice that incorrect letters or
functions are appearing. Press the Calibration icon.
Use the stylus provided with the GPS (or any other
stylus) to accomplish the task. Use the stylus to
press on the target which looks like a plus sign [+].
The target will move around the screen. Continue
this process as it moves to the left, right, upper, and
lower parts of the screen. You may need to repeat
the entire process once or twice if the screen is
more severely out of alignment. Tap <OK> when
complete.
