The chip was easy to install. The on-screen instructions were clear. My low score is because this is NOT a 2020 update. I can't say exactly when it will be covered, but there are locations and roads built in the Raleigh, NC metropolitan area between 2018 and 2019 that don't show up in the navigation. It's a bit like a lure and a switch. It's an improvement over the 2017 dates my car came with, but not by much.
