It does what it's supposed to, after a fashion. I've used Garmin GPS units for a couple decades, hiking the backcountry and piloting the sky with joy and confidence. However, this unit's user interface is ""clunky"" in that the system seems slow to respond, requires what I consider extra steps to modify a route (and no editing at all after a ""trip planner"" route has been saved). Trip Planning absolutely requires another device to research intermediate stops and consistently delays the entire process by forcing you to wait while it calculates routes from your current location to your waypoint selections, even if you are trying to set up far-away points for next week's trip. Also, Garmin's database does not include some RV parks that both Google and Apple maps recognize immediately (is that a revenue stream issue?). Additionally, the touch-screen interface is terrifying to use while driving and it's the only reliable input option (voice recognition still is not a mature technology for any company). This is a very disappointing $350 I spent, but since it also -allegedly- accounts for the RV's dimensions and weight in route calculations, I reluctantly kept it.On the plus side, having active voice and pictorial guidance for which lane to use in approaching upcoming exits is comforting.I'll try to update this review after our long trips in the next several months.
