Default furuno plotter swapped ends

Just finished putting an update on my plotter, and somehow while fumbling around, the antenna input to the unit has reversed. Boat is in right place on screen, but turned around.

Is there a quick fix?

Thanks for any replies.

what machine...Navnet with radar dome? quite common as that is the "default" when using a dome, but works correctly with an array...not sure why it has to be that way, but it is.

It's the 1834/1920 setup with dome. Has been pointed in the right direction for years, and I probably messed with some control that moved it.

did you perform a master reset? if so, you'll need to tune it again.

Your chartplotter is showing your boat's position on the chart, but pointing in the opposite direction? When sitting still? Or also while moving? Boat heading on the plotter is usually controlled by the heading sensor input. without that input, the boat heading is unknown until the boat moves, then the GPS can calculate a heading. Did you lose your heading sensor input?

This sounds like the answer. Boat has been tied up during this whole episode. Maybe going for a ride will work it all out.

Didn't knowingly perform a reset, but it could have happened with the software update.
