] is selected, the barometer should auto calibrate each time you power the Montana on.
Thanks for the input. I do have " Elevation" selected in the data field. The term " elevation" usually refers to an elevation regardless of barometric pressure which is why I selected it. I did suspect that Garmin had somehow coupled this to the units barometer. I will try your suggestion and see if that works.
Since the unit has the abilty to display barometric pressure and it has an " auto calibrate " function, then one variable it needs to know is actual elevation for it to calibrate. I will try your suggestion when I get home.
