    hey all. my Zumo 660 does a weird thing and I can’t figure out the issue. When it’s hardwired to the bike and it early in the morning or in the evening it automatically dims the screen, so much that I can’t see it. The display color mode is on daylight so it should be bright. If I take I take it of the bike the screen goes bright. Any suggestions?
