This being my second ATOTO S8G2, product has been without issue, installation was simple, default system setup performs adequately.
Of course, the attraction of these android units is their customizability. While this exponentially complicates the challenge of ATOTO support, they do an admirable job, and promptly.
While I do use ios and android devices, I see no use for carplay or androidauto with this unit, and therefor untested. Wireless aptX does function correctly.
The display cannot be tilted in any way, but it views exceptionally well at angles, and installation is dead simple. The huge screen makes using my rear view camera comfortable, and the screen update on this view is analog and very instant, and is useful even looking ahead, if you have peripherals.
This unit should perform well for anyone, but for those wanting to push the limits of a head unit function, it is superb. Also noteworthy with my received unit is that is shows 4 gigabytes of system memory over the listed 3.
