I have a similar Chinese rip off on my bike and my Nav V sits on a shelf redundant. I am quite happy with what it does, but IT DOES NOT work with the Wonder wheel. I have checked the advert in the link you posted and it does not claim to work with the Wonder wheel, just power the phone. It would be a first if a spurious part works with BMW electronics and software as I'd be surprised if they'll licence a Chinese company to interface with their systems.
As I said I'm happy with what I have but if these integrate with the bike's system at £35 a pop I'm in for one.
