French electronics manufacturer Oxygen Audio will introduce an audio system at CES 2011 that uses an iPhone as the head unit interface. The O’Car audio system allows your iPhone to dock right to the front of the audio deck. A cantilever swivels the phone horizontally or vertically, and angles it in any direction.

You’ll be able to use your favorite apps for traffic information and navigation or whatever new technology comes to the market–as long as it goes to your phone. A downloadable app controls the entertainment system, which offers AM/FM/RDS radio, 4 by 55 watt amp and subwoofer control, and also provides seamless app multitasking.

Every car I have owned for the last six years or so has had a double DIN stereo in it. I thought the single DIN stereo was outdated, but I guess there are enough cars out there that there is still a market. MD Sound has announced a new single DIN stereo called the MD-DVD3.5T with a color LCD and a low price.

The radio has a 3.5-inch LCD on a flip down panel that can play DVDs and other media from flash drives and SD cards. The radio supports DVD/DVD-R/MP3/MP4/VCD/CD/CD-R/CD-RW media. The radio also has a built-in AM/FM/MPX tuner.

After countless iPod/iPhone docks that are all pretty much the same, the XML8110 Mechless Mobile Audio system manages to be unique. It combines an iPod docking station with a car stereo. On the surface it looks like a standard car stereo, but when you flip it down, the integrated universal iPod dock is exposed.

It will let you dock your iPod, charge the device, and users will be able to access all the playlists and music on the device. It also comes with a built in FM radio, EQ presets and an AUX In for connecting other devices. It will also allow users to take calls from their iPhone. With a corresponding iPhone app that’s also in the works, the integration between these two devices gets better.

HD Radio is looking more and more like it’s here to stay as consumer companies slowly develop products which pick up the radio industry’s answer to satellite radio. The latest of these, and apparently also the first auto manufacturer putting out cars in the United States with this technology, is Volvo.

Volvo said today it will begin offering HD Radio on almost all of its models in fall of 2008. Volvo Cars of North America will specifically be offering factory installed HD Radio receivers as standard and optional equipment in a variety of models, including the S40 T5, V50 T5, C30, C70, S80, V70, XC70 and XC90.
