Step 2b - Install the GPS Antenna Connection (optional)
GPS connection is required for Tracking and Emergency messaging.
The GPS connection is optional if the Tracking and Emergency function
are not required. If connected, and tracking is enabled, position or location
information will be shown on your tracking messages and alert messages.
The GPS connection provides a 3.3V source if an active GPS antenna is used.
Install the GPS antenna in the appropriate location and then connect
it to the SMA female connector on the antenna cable coming from the
rear of the PotsDOCK Extreme.
