Today I did the update from v7 to v8. All seemed to go well but now my heading sensor PG500, and Radar (NXT) keep disconnecting ever few seconds. The Heading sensor is also used by another unit and never fails on that unit(Raymarine unit). None of this happened running v7. So 2 questions is it a v8 compatibility issue? Second where can i find the V7 updates on the furuno site so i can re-install that version? Any help would be appreciated…
