TMK, the only BMW that came with the SMG was the E46 M3, and maybe the M-coupe/roadster (but I don't think so).

Most of the manu-matics that BMW puts in thier cars are called, I think, Steptronic or something catchy like that. Now, I don't really know about the new cars with the manu-matics, but the ones that came in the E46, and other concurrent models, bascially have a "secondary" shift gate that shifts the transmission into manual mode, from there one may up shift/down shift with the gear selector on the center console.
