Microsoft has received a patent for a car stereo that would include a docking station for an MP3 player or other handheld device.
The patent awarded this week by the U.S. Patent and Trademark Office is for a car stereo that includes a docking station for an off-the-shelf handheld computer.
While the station is likely to support Microsoft's Zune portable media player, the patent indicates that the dock also would support third party devices. The patent says that the stereo would include an input/output component that would enable the car stereo to tell the handheld computer "which one of a plurality of different appliance types the car stereo is."
The patent is the latest move for Microsoft in in-car entertainment systems. Ford Motor in January said it would offer a factory-installed communications and entertainment system based on Microsoft automobile software called Sync.
The application enables people to bring into their cars nearly any mobile phone or digital media player, and operate it using voice commands, or controls on the vehicle's steering wheel or radio.
