There have been several posts that people in the UK have got the leads included, but I don't think there is a hard fast rule.
Even at £40 I will still take it, BMW know they are on to a good thing, and basically have the consumer over a barrel. In the grand value of a £40K car andother £40 is irrelevant, principally I totally agree that it should be thrown in though!
They can argue that the adaptor is a USB adaptor and not Ipod, the lead makes it Ipod specific? They could be giving £40 leads away for nothing!
Either way still can't wait for it to arrive, hopefully my powers of gentle pursuasion will get the lead thrown in!
