Sony came up with a novel use for an antitheft removable car stereo faceplate: MP3 storage. The Sony MEX-1GP stereo head unit does everything you would expect from a modern car stereo, such as play MP3 and WMA files off CD-R/RWs, but it also includes a gigabyte of storage in the removable faceplate. Hook the faceplate up to a PC via its USB connector, and you can drop your music on to it. Then take it out to the car, and you can navigate the stored files from the stereo head unit interface. One gigabyte is approximately 500 songs, so the unit will carry most people through a road trip. If other types of data can be loaded onto the faceplate, it should please any Johnny Mnemonic-style data smugglers.
