Mega live orientation

Since purchasing my Mega Live, I had it installed on the starboard side of the boat on a pole mount. Yesterday I installed the Low Pro Rod rack which puts the transducer on the port side. I took it on the water today and adjusted the settings from starboard to Port. But it doesn't make any difference. Does the AHRS setting automatically determine which way is facing forward? I noticed that when I turn that setting to off, I can toggle port and starboard selections and the image will reverse. But as long as that setting is turned on to pitch and roll, no matter whether you select port or starboard it is in the correct orientation to see your jig in front of you. Just want to make sure that the unit is acting like it's supposed to which sounds like it is but just want to be sure.
