Received my order about 10 days ago. So far I have only been able to take it out for a short ride in the city, using Waze and Spotify. I like it a lot, screen is of a very good quality, but it would have been nice for it to be a bit bigger.
So far, whatever data I have used (bike data like speed, rpm, lean angle, temperature, compass, etc) seems to match the data on the bike and it's accurate.
I have only used Android Auto, so I have no idea on how Car Play works.
As a conclusion, it's a very nice and useful device, but the screen size could have been bigger. :)
