I get so frustrated when I'm in a new car and there's no way to plug in my iPod. Get with the times, car manufacturers! Or bring them up to speed yourself with the O'Car, a dedicated iPhone-based head unit.
Oxygen Audio's O'Car has a RDS radio tuner and a 4x55W amp, but the magic happens when you strap in your iPhone. The rotating mount charges your phone and holds it horizontally or vertically, allowing you to play tunes through the iPod app, Pandora radio or whatever else, put your iPhone to work as a GPS navigator, or make hands-free calls over your car's speakers. Or play Infinity Blade while you're in bumper to bumper traffic.
Aside from radio, the O'Car doesn't do much on its own, so hopefully it won't be too pricey when it's officially debuted at CES in January. (Update: Our pals at Gizmodo France tell us that the unit is on sale there for €300, about $400.) All I know is that I wouldn't shed a tear if I had to retire that stack of half decade old CD-Rs that are shoved in my car's every nook and cranny. [O'Car via Wired]
