".....Do this, Don't do that, can't you read the sign.........<They're everywhere>I've left my Qi charger wired and on in my truck now for about 9 months... no dead battery issues yet. They do charge a bit slower though. To switch screens, I just talk to my phone... "Okay Google, navigate home." "Okay Google, Play my music" that way, I can use my phone for navigation and music without having to crowd up my windshield... Blocking up the scenery, breaking my mind.
