From what I've heard, if it's the same one I think you are talking about, a dealer that I work with told me something maybe even up to 3 g's. That's just what I've heard, but I'm not too sure. That's the new unit going in on that Mercedes project right?

they had it at CES. It looks really nice and i did hear that it is about 3gs with the H900 being about 4gs. THey had it in a Mercedes S55, but the really nice car is the M3 that they had it in. FYI: the power source is external for the 7990.
