On a similar note, I found this:
Griffin Technology: TuneFlex AUX HandsFree - Mount, charge, and play your iPod or iPhone in your car
It would be perfect for my car since the cig lighter is right at the base of the console in the ashtray compartment so needs the bendy arm. But what I'd need is a female iPod/iPhone to micro usb connector. Anyone know of one? No luck at either google or ebay so far.
