Does the 2016 Toyota Corolla have GPS navigation system?

Yes, Your 2016 Toyota Corolla should have a GPS navigation system on-board. Toyota calls this the Scout® GPS Link, and it provides You with directions, traffic-based commute information, and even gives You some hands-free voice command capabilities. Additionally, if lets You keep track of where You've driven, as well as Your favorite destinations. There's an accompanying app, so You'll need to have a compatible iPhone or Android smartphone to use it to connect to the Entune component in Your vehicle via bluetooth. It's pretty cheesy, but Toyota actually uses the app on Your phone to download the nav data, so if You've got a limited data plan, heads up on the potentially high costs there.
