Product Questions
Ask a QuestionYes, the GS25 is compatible and connects via NMEA2000 to the NSX series.
Answered by Administrator on 2025-12-15To do radar overlay you will need the GS25 with a NMEA2000 starter kit. If you want to do radar overlay and MARPA, you will need the Precision 9 compass and a heading sensor.
