And if you want an interim solution, you MIGHT be able to use a standard Lightning to USB cable plus a standard headphone cable running from the iPhone's headphone jack to the car's AUX In. However, that won't sound quite as good because you'd then be piping amped audio rather than line-level audio into the stereo.
It will. The media messed this up big time because the original product description on Apple's site said "iPod Out not supported", which some press morons took to mean analog audio or external playback controls, when in fact it's the interface that BMW calls PlugIn. Both analog audio and external playback control will work just fine, and in fact the product description page has since been revised to remove the iPod Out note and just say "Video output not supported" instead, and it also explicitly says "Enables analog audio". You can see it right there on Apple's site.
But even if it weren't actually stated there, I figured the adapters had to have a built-in DAC to enable analog audio anyway. In addition to the fact that NOT supporting that function would make these adapters useless to practically everyone, why else would these two Lightning adapters be $10 and $20 MORE expensive than an entire Lightning cable? That alone suggested to me that these adapters were packing a bit more than a set of pin remaps.
Audio = yes. Video = no.
I've had mine on order since they first became available -- will post when it arrives, and advise what is does/doesn't do.
