Ah, okay, I checked out bsw's site to see what you are talking about.
The speaker upgrades they have listed for the 3 series bundles the 3 together with the m3. The base is the standard system for the 3 series and the hi-fi is standard system for the m3, while the logic7 is the premium for the 3 series and individual is the premium for the m3. Your BSW upgrade would be $110 since you have the premium 3 series stereo. Hope that makes sense.
