Highest Compatibility For Vehicle Fit/Installation
There has been a consensus on the dimension of double din in dash metal case for installation (178mm*100mm/7"x3.94"), But there's no agreement on dimension of the front face-plate part. So lots of users encountered issues /hassles with other 2 din head units when installation dash kits are applied.
Most installation dash kit brands provide 2 din mounting frame with 174mm*98mm opening (Metra, Scosche, PAC dash kit,etc).
ATOTO A6(Y)27xxx can fit perfectly! No trimming/cutting job is needed!

Unlike tablets / phones that are used more frequently indoors than outdoors, the Android car radio are running in a place where strong sunlight makes the driver see the screen more difficult than in other cases;
After examining the current android car radios with the screen, we found that maximum brightness of these ones are no more 350cd / m2, so all the A6 are equipped with a better brightness screen and the standard version ATOTO A6 uses a screen of 400cd / m2, which is about 14% brighter than the average Android car stereos

To speed up the boot time of Android system from 25s to only 2s is never easy.
