Doesn’t work with new iPhones. Google Maps is better.

iPhone 8 doesn’t connect to Scout, Entune, nor Remote Connect.
Requires using BOTH Bluetooth AND wired USB together. Even then, it tries to connect with passenger smart phone!
Inaccurate maps and bad directions.
Puts “centered” cursor in bottom third of screen, so going South doesn’t show roads ahead.
Phone Compatibility Lists online are almost four years old. Help Desk says keep contacting dealer!
Requires four apps on phone: Toyota Owners, Entune, Scout, and RemoteConnect. These are all ONE app on my four year old GMC that work every time on new iPhone.
Scout (and Entune) won’t even load on vehicle even when running on iPhone8.

Best solution: Glue your phone over the Toyota screen and run GoogleMaps or buy a Garmin.
