Edit: I reread this, and saw your mention of pre-combobox. I'm assuming this means your build has the same components/functionality as mine.

I know in 2011 there were some updates to the BT functionality, i.e. you shouldn't even need this. Although, I've also heard stories that if your build was before sometime in 2010 you didn't get these updates. Is this the case for you?

I tried something like this from ThinkGeek this week, it didn't work in my 2010 e90 335. Has anyone tried this with a pre 2011? I've been looking for something like this for a long time.
