That looks like a really nice unit, on paper at least. And all for the cost of a map update disc!

I bought an all in one thing off ebay for my last car that also seemed great from the description, but in reality it left a lot to be desired. The apps were not very well integrated and most worked poorly. The nav unit muted the radio for about half a second before the instruction, then the same delay after. I love the way the BMW lady just tells me over the music.

If this turns out to be a true plug and play replacement for the BMW nav/computer system, and it functions more like an AVIC than a dodgy chinese unit, I'm in!
