I'm brand new to this forum and need some help. I've been using a Garmin RV660LMT for several years and am quite familiar with its operation. Of late, it has lost its electronic mind and is no longer useful. It turns on and off randomly (the same in 2 vehicles with 2 different power cords). If it doesn't turn off, the screen brightness suddenly goes way down, and then back up. It forgets the current location and has to re-find itself. Occasionally it displays just a plain white screen. It's just behaving very oddly.\n\nWhat I need is a Garmin GPS with:\n1) a 5 or 6 inch screen\n2) that accepts a download from Basecamp with a complicated, long routes, that has enough memory to store 20 or so such complicated routes\n3) that will connect to a BC-30 camera wirelessly\n4) that has a wide POI knowledge\n5) I do not need specific RV help as the RV660LMT has\n6) Cheaper is better than more expensive\n\nAny ideas?
