The original Radio/Navigation system om my 2016 Toyota RAV4 Hybrid suffered from the known problem of decreasing response and even dead spots. Toyota told me this can be fixed by replacing the unit which would cost at least €600,-. With the available aftermarket Android systems completely new for that price really a no-go but some research showed that the touchscreen itself could be replaced solving the problem. As I’ve still 2 years of map upgrades from the last 3-year renewal I decided to give it ago. Attached a PDF with the steps needed and what touch screen to get. For less than €20,- including shipping I got myself a fully functional unit again! And you do not have to be an expert to get the job done....
