GPS signal okay but no DGPS on my GP35

Question

​My GP35 works as a GPS but the differential correction is not functioning. What could be wrong?

Solution

​Please check the DGPS SETUP menu and confirm that BEACON is set to INTERNAL and STATION is set to AUTO. These settings control the differential operation. Also check I/O SETUP menu, set DATA 2 to BEACON. If this does not correct the problem, have the unit checked by an authorized Furuno representative.
