How might an installer verify correct GPS sentence to marine DSC VHF radio?

The main idea is to verify that the radio is actually receiving and using GPS data by checking for your position on the display. When a GPS sentence is being received, the VHF DSC radio can use the latitude and longitude from that data, so the display will show your coordinates. Seeing those coordinates confirms the GPS feed is working and being parsed by the radio. Other actions don’t directly confirm the GPS data is flowing into the radio: forcing a distress call won’t prove GPS is being received, a generic GPS “confirmation” readout (if available) isn’t universal across models, and asking someone else for a position report depends on external stations and doesn’t verify your own GPS feed.
