It appears the the three units I mentioned are considered cheap chinese junk according to these forums. I'm not so concerned about price. I just need something that is compatible with my car and that works well.
Im wondering what OS these units have. If its Android then I can go to the google play store and download any app? The Kenwood seems to be android compatible but Im not sure what that means. Basically what is vital is that I can use Google maps, music services such as spotify and pandora, am and fm radio (DAB+ would be good), bluetooth for multiple devices. Obviously it would need to automatically cut into the rear camera when put into reverse. Are these units basically fully functioning touch screen android tablets?
Thanks
