I bought the H series Android 12.0 Carplay 12.3 inch Full Fit Screen for 2015 Mazda3. After watching the install video on there youtube channel, and downloading the Manuel from the e-mail they sent. It was all plug and play, there is a lot of extra wires which made it a bit harder to do, but works well in my car with BOSE sound. I do still need to look in to the mouse wheel and volume knob on middle dash but rest works like a charm. steering bottoms works right out of the box And it's super fast ! Bose sound system has never sounded better !
