GROM USB Car Interface
The GROM USB Car Interface from GROM Audio is an accessory that aims to simplify the playback of media files on an original car stereo.
GROM USB Car Adapter enables you to bring your favorite media collection in a car, easily access it, shuffle songs, skip between tracks, and adjust volume — all of this only with OEM car stereo head unit or multifunction steering wheel controls. An exclusive technology and best-in-class audio decoder brings up a new level of listening experience – clear sound not poisoned by long wires and media player line out drivers. Extended control capabilities allow managing thousands of songs limited only by USB device capacity. Just connect your USB memory stick to your car stereo system through GROM USB Car Interface and enjoy the ride!
Unfortunately at this point in time, the GROM USB MP3 Car Interface only supports Audi, BMW, and Volkswagen car stereos so those with other makes will just have to wait. There are plans to increase its compatibility to work with Acura, Chrysler, Honda, Mazda, Mercedes, Škoda, and Toyota as from September 2008.
