I don't have my unit here, but
go to setup tab
scroll down to readouts
scroll over and see 1-5 readouts
you can arrow over on the individual readouts to change the display setting.
Just a thought. easy check and easier than changing the biscuit.

Best thing to do is use a handheld that works and verify the HB unit next time out.
Don't forget folks. i ain't been on the water in 4 months. I just doing recall on this stuff. Sometimes it is fuzzy. Recall that is, not my chit.
my m.p.h. never went to o.o although it was pretty windy. Could not control boat most of time speed was in reverse or side ways. I thought of handheld also next time i have a garmin.
Oh cane pole i almost forgot I have a 14ft. john with a 10hp. against the wind flat out speed said 6.6 to 6.9. does that sound about right.
