I have a 2019 RAV4 XLE Premium fully loaded but lacking the Navigation. I really want to have the navigation. Currently I am using a Garmin DriveSmart 50. But I am wondering if I can swap the head unit to an Entune Audio Premium with navigation. I think it's possible because I know you can do this with the 4th gen RAV4s like the 2017 model. You can buy the head units online and just swap the original one. But I can't find the Entune Audio Premium head unit online.
