You posted on the wrong section. But anyway I own a m45 and the only way I know to set it on auto is to set your headlights on Auto. So whenever your headlights come on your nav will get dim. I hope I made it clear enough.Tenacious--M wrote:When driving at night I always have to manually switch my 2007 M45's navigation screen to night mode. Doesnt this have an auto feature that will auto select this based on the lighting for you?

As noted above in a previous post-this switch will adjust your night mode/day mode anyway you want it.EniGmA1987 wrote:When not on auto (manually turning headlights on), my navigation screen switches to night color when my lights turn on.
