Owner’s Manual 33
• Buildings can block satellite signals. Setting up the GPS receiver in a
vertical window blocks at least 50% of the sky. Trees also can block
satellite signals.
NOTE: A window with a Southern view, rather than Northern view, should be
used to receive signals.
The Receiver performs at its best when the battery is fully charged. If you are
having trouble receiving signals, try plugging in the Receiver.
The colour of the vehicle arrow on the map indicates the connection strength
between your Receiver and the satellites:
• Green indicates that 4 or more satellites are available. This is the
strongest level of GPS connection, sometimes referred to as a 3D fix.
• Yellow indicates that 3 satellites are available. This is a weaker level of
GPS connection, sometimes referred to as a 2D fix.
• Red indicates that less than 3 satellites are available. The system will
seek additional satellites before providing navigation.
