I didn't even get to the head unit portion as I had so many problems with the tablet. I tried to do the factory restore, but I couldn't (I don't remember the error, but it was something like it needed the SD card inserted with the original image). No, all units ship with that stupid "I love you" screen and the manufacturer said it cannot be removed. But that's an example of how immature this company is. Even if you're technical, this is not a device that's worth it at this time, especially if there are problems.
