To me the key thing is the android operating system. That allows for adding features the radio didn't come with. Such as the ability to reset the mpg, trip meter etc which the dynavin cant do.

Plus at double the price of pretty much all the other aftermarket direct fit radios out there the dynavin prices itself out of the competition since it brings nothing to the party the others don't already have.

An American distributor is the dynavins only real claim to fame which is nice but its not double the price nice in my opinion.
