Hello. Just purchased 2019 Legacy Sport. I have tried searching but haven't found a solid answer. Is there a sensitivity setting for the auto high beam assist? Driving on the highway the lights will switch to lows even with no oncoming cars. Also with the homelink rearview mirror, if you hold in on the green button that turns the auto dimming mirror on/off, the compass goes away and it come up with number 1-15 like its some sort of setting. Does anyone know what that does?
