As of last week, I have installed the app on my phone and have tested out my CarPlay with what I can without having an OBD-II scanner yet (should be here soon though!). In addition to that, I have signed into my Toyota connected account (after I got the invite code for it) so will see what that brings up once I get into the car and hop on over to the app on CarPlay.
Looking forward to testing this out more as you start to add more features!
