Hi all, I am sure this gets asked a lot, but I noticed a thread via google that was quite old, but it mentioned you have to purchase a B&M usb adaptor. They are very expensive, do I definitely need one for my car?

In my last car i just used a single pin auxiliary cable and was hoping to just use that again.

I am driving the Fiat 500, automatic, year 2012

thanks in advance

S'ok have worked it out.

For anyone looking for the same advice, just turn on bluetooth on your iphone, plug in single pin cable to phone and the aux point in car, and double click CD on radio and AUX will appear and your ready to go

which is that expensive device? what it does?
