Navigator VI on a 2016 BMW GSA. In one word JUNK. In three years with very little seat time in 2020 I will be sending my second unit in for a third replacement. While riding the map screen will begin to shake and move around to other areas and then freeze up. All support tells me is that there are multiple problems. Really, in this amount of time shouldn't you have had this worked out. It would be nice to have a reliable GPS unit while on a trip. It's nice when it's working. But reliability is important and Zero stars would also be appropriate at this time.
