I bought the BMW adapter in May right after buying my car, and it didn't work
even though I was told it would!
Autoleads are developing one, if you do a search you'll see that myself and another few members of Mini2 have been after this for aggggeeeessss.
We even emailed Autoleads (who said it would work) and they say it will be early this year as thyre still looking into it.
