I've got some good news and some errr not so good news, well unless thins have changed.moonshine said:
The wireing on the Mini is the same as the Beemer 3 series. Now I got a Sony MD unit for my mums beemer, and when the car arrived, what do you know the standard spec had been increased, so it had the MFSW. So I had the radio fitted and asked about an adapter cable that would work with the steering wheel. Anyway the guy hadn't heard of one, but found one for £30. What he did say tho, was that I was very lucky, as appaerntly his supplier told him that the only Head units that work with BMW MFSW are sony's.
Of course that is only if things haven't changed, that was 18 months ago and I've not seen any other adapters on sale.
My advice. If you've got a kenwood MD played I'll give you a swap for my Sony MD, as I like Kenwood (depending on model) and I'm not gettin the MFSW.
.....on second thoughts no one but Sony do an MD Changer so I better not do a swap
See if you can get a trade in for a sony?
