Any information / advice about this product?

Hi there guys

I've got a E46 318i and it has the old BMW Business R/T, which I've been thinking of replacing with this:

All I know is that the unit is of Chinese origin (what isn't these days?) and google and youtube have revealed almost no info about the product.
Anyway, has anyone got one of these in their cars, or some other unit that I may consider?

Any info or advice is appreciated.
