Looks like Visteon is making a play in the portable satellite radio market and has filed a patent (application # 20060094349) for a Dockable portable satellite receiver.

Here's the abstract:

A portable satellite receiver includes a tuner, an antenna, and an amplifier. The portable satellite receiver has a protective housing enclosing the tuner, antenna, and amplifier. The portable satellite receiver is configured to interface with an accessory device through a communication link such that the accessory device receives audio signals from the portable satellite receiver over the communication link.

Interesting. Reading further into the application, here's the translation from the patent-speak (which many times is written to throw off 'the competition'):

The portable satellite receiver includes a satellite antenna, and a "protective housing" which encloses the satellite tuner and a "media player." That media player is essentially a MP3 player, that also has the ability to record the satellite radio signal. On top of that, the media player will interface - wirelessly - with a docking station (or what appears to be called the "satellite entertainment system"). The "protective housing" also has a plug to interface with this docking station.

So, they're essentially applying for a patent on a live satellite radio/MP3 player. Hmmm...
