Will BMW Feature iPhone Integration?

Autospies reported Tuesday that BMW may be the first auto manufacturer to make its cars iPhone-friendly. “A reliable source” told Autospies that iPhone compatibility – beyond “just Bluetooth” – might be built into the next BMW 7-series (out in 2009).
There’s not much evidence to back this rumor up, but it’s worth mentioning that BMW was the first auto manufacturer to team with Apple on integrating the iPod into its cars via a glove compartment iPod hookup controlled by buttons on the steering wheel.
