For the handful of audiophiles who simply cover their ears with their uber-expensive cans when the rational crowd invites them to stop hoping for SACD to take off, here's to you. Sony has launched the "world's first" (we believe it, actually) in-car head unit that supports 5.1 SACD. The double-DIN XAV-W1 touts a seven-inch WVGA LCD, SACD / CD / DVD playback, Dolby / DTS support, 3.5-millimeter auxiliary port, seven-band equalizer, 52-watt x 4 internal amplifier, a trio of AV inputs, an image viewer, MP3 / WMA compatibility, and comes ready to play nice with your iPod and satellite / HD radio receiver. Granted, this thing will run you more than some in-dash navigation systems, but paying $800 for this sure beats retrofitting a traditional universal player into your glove compartment.

Being the mass transit junkies that we are, we don't spend a lot of time in cars, flying or otherwise, but we know many of you hit the highways each day, so we're presenting to you Sony's new Bluetooth-enabled head unit. The MEX-BT5000 acts as a hands free kit for any Bluetooth phone (although we're sure they'd prefer if it was one of their own), giving you access to up to 50 of your contacts and six of your speed dial entries through its "high resolution" screen and integrated noise-reducing micophone.Once you're done risking everyone's life talking on the phone, fire up your Bluetooth-equipped DAP -- or just stick in a CD -- and you can stream high-fidelity audio throughout your ride, while checking out on-screen track info and navigating your music with the wireless remote. Sure, this isn't the first time we've seen most of these features jammed into a head unit, and at $400, it's still not the cheapest, but we thought it might help hold you over until the CD-ripping 2007 Infinity G35 starts showing up on sketchy used car lots.
