GPS
It is important to test the GPS performance before the location of
the unit is decided.
Construction material (steel, aluminum, or carbon) and heavy
structure might affect GPS performance. Avoid a mounting location
where metal obstacles block the view of the sky.
A well placed external GPS module can be added to overcome poor
performance.

Note:
Consider the lateral swinging if mounting the GPS sensor
high above the sea level. Roll and pitch might give false
positions and affect the true directional movement.
Touchscreen
Touchscreen performance can be affected by the location of the
unit. Avoid locations where the screen is exposed to:
• Direct sunlight.
• Prolonged rainfall.
