Digital Lifestyle Outfitters (DLO) is now shipping TransDock Micro, an iPod charger and adapter that uses FM to link your iPod to your car radio. Nothing new there, but the TransDock can also charge up other USB devices such as the Motorola RAZR, offers four preset stations, and works with all the iPods including the shuffle.
Plug the unit into your car's cigarette lighter, and you can connect another device such as a portable DVD player or PSP into its auxiliary input, letting you play that audio through the car stereo, too. Not bad for $70.
