Garmin Montana 700i at software level 10.50. Display Orientation lock is not working. I have it set to auto and it worked before.
Now there is no switching from portrait to landscape when I rotate the 700i.
In order to make the display switch I have to go into Settings_Display and change Orientation Lock from Auto to either Lock Portrait if I want to change from Landscape or Lock Landscape if I want to change from Portrait.
Then I go back to and change Orientation Lock to Auto; even though Auto no longer works.
By the way, when I turned the Montana 700i on to verify the wording in Settings it updated to software level 10.80. Unfortunately that did not change the current Orientation Lock behavior.
