Humminbird ONIX Operating Manual page 221

3 | Select GPS Sources (optional)
The ONIX control head defaults to the internal GPS receiver as the primary source (GPS [1]). If you connect an external GPS receiver
to the control head, it will be assigned as the secondary source GPS (2).
If you connect an external GPS receiver to the ION control head, it will be assigned as the primary source GPS (1).
GPS (1) provides position data, Speed over Ground (SOG), Course over Ground (COG), waypoints, routes, tracks, and navigation
calculations to the control head.
GPS (2) provides position data that is displayed in the GPS (2) data box.
You can also manually change which GPS receiver is the selected source for GPS (1) or GPS (2). For example, if you've connected
an external GPS receiver to the ONIX control head, you can assign it to GPS (1), so the control head will use it as the primary source
(instead of the internal GPS receiver). If the control head is part of an Ethernet or NMEA 2000 network, you can also select the GPS
receivers from the network.
