Model S 2017. Users of the corporate Blackberry Work app or Good app know that these apps won't "share" data with the Tesla app and will not display appointments on your car's screen. Therefore you need to use a personal calendar app that will. You could re-type every appointment twice, once in each app OR a short cut I use is this: As you create a calendar appointment in your Blackberry Work app or Good app choose the feature to "invite attendees" Email it to your phone's personal email, open it, and accept it to your personal calendar app. I find it's easier than typing every appointment twice. It's also easy to change appointments. You need to keep the Tesla app open for this to display on your cars' screen.
