These are from SevenTour. These are the APad-156. They are a little bigger edge to edge at least 16. Screen size states 15.6. Mounting hardware is nice. Pretty slick setup and very clean. Mount connects to headrests poles and kind of hides in the middle of them. Wiring is pretty simple just find a 12V switched. I've seen some people do a quick wire to their OB2 port. Don't go that route. The OBD2 is not switched, also Mazda's are known for loose ports. Instead go for the fuse box, or trail back to your 12V in the rear, which ever you like better. To me the rear is easier and also switched.
Yes these do stream, something else I really like is you can hot swap the start up screen with the Mazda logo. I used a high res Mazda logo. There is a code to do it (HR8888). Then you just add a jpeg file.
The screens also send audio to Bluetooth, FM, or headset port. They have internal memory storage and you can add both an SD card and USB. I recommend the tiny ones or the kind that can bend 90 degrees, just looks cleaner.
