Not award winning but not horrible
I just bought a 2016 highlander yesterday and connected the Entune app in order to get Pandora working in the dash. The UI is very dated, but I am fairly tech savvy and was able to get through the process without issue. Pandora works just fine. Kinda weird that you need an "app" at all to make the process work. My Mazda CX-5 had the pandora app built in to the stereo and just connected to the phone on its own. Would be nice to see Spotify and Apple maps but hopefully Toyota will add new apps soon.
