Think again. Walter Mossberg isn’t impressed:
I’ve been testing the system in a $54,000 BMW 330Ci convertible, lent to me for a few days by BMW. I have tried several different iPods in the car, including a brand-new, fourth-generation model. My conclusion: The BMW iPod adapter works, but in a pretty crude way that will likely leave the iPod cult hungering for more. It’s a decent first step, but that’s all.
*****Still, the BMW setup was far less distracting and ugly than my normal system: an iPod stuck to the dashboard with Velcro, plugged into an audio jack with a Radio Shack cable, and connected to my cigarette lighter for juice.
Update: Today’s New York Times has an article on the various means of connecting an iPod to your car stereo.
