Sony on mid-Tuesday launched a spring update to its Xplod CD head-end units. Both the high-end GT920U and its lower-cost GT620U alternative are designed as much for purely digital media in mind and include both a USB port at the front and a navigation interface dubbed Quick BrowZer. The new interface lets users quickly browse unprotected AAC, MP3, and WMA songs by playlists rather than a raw file view. The two decks also recognize these same formats burned to CDs, Sony adds.

As the high-end model, the GT920U also adds support for iPods as well as optional HD Radio and satellite radio tuners. Either outputs 52 watts per channel to as many as four channels and includes three pre-outs for more complex in-car audio setups. The GT620U is already available in shops for $170, while its more upscale counterpart appears next month at $250.
