Sony has stepped into the HD Radio arena now with the XDR-S3HD tabletop radio and the XT-100HD mobile tuner.

The Sony XDR-S3HD tabletop targets the retro-chic crowd with a large back-lit blue LCD display set in a mesh-covered front panel and wrapped in a cherry wood finish. Along with HD Radio support, the XDR-S3HD also sports MP3 playback (through an auxiliary cable), and 20 presets for either the AM/FM band.

Expect to see the XDR-S3HD in stores in July for about $200.

Then there's the Sony XT-100HD, which is a hideaway mobile tuner that connects through the Sony head unit's bus interface.

On top enabling your car to receive HD Radio, the unit will pump any available PAD data to the headunit. Also expect to see the XT-100HD available in July, running around $100.
