Sony unleashed two CD tuner/changer controllers with the announcement of the CDX-GT610U and CDX-GT616U, lining up under the GT series of players for your vehicle.

Both models play MP3, WMA and AAC formats from a variety of music sources connected to the front-panel USB socket. Yes, it's that simple to plug in your device and listen to the music in your vehicle. If that's not enough, the CDX-GT610U/CDX-GT616U can also handle CDs packed with MP3s or WMAs.

With a largish 13-segment display to show off the disc, track and station data apart from equalizer, both the models come with a sub-credit card sized remote control. Thanks to DRIVE-S chassis technology, you can enjoy superior quality audio.

The licensed BBE-MP processing improves MP3 quality by enhancing higher harmonics that are otherwise lost during compression. Sony's DSO II (Dynamic Soundstage Organizer) technology elevates perceived position of the audio from floor-mounted speakers to ear level for a satisfying experience.

No word on the pricing yet, but the Sony CDX-GT610U/CDX-GT616U CD tuner/changer controller will hit the markets in January 2007.
