The android head unit does not like the android smartphone, normally we don't suggest our clients flash the item when the unit work as it should.
There is a similar android 5.1 head unit, but the factory told us that the android 5.1 firmware was not available on android 4.4 unit, and the result we tested also show the android 4.4 unit could not find the 5.1 upgrade file, I think there may have some difference between the hardware components inside. Hope your understanding.
