Looks like General Motors is up to something. In a recent U.S. Patent application, GM has spec'd out a method for "customized music delivery" to vehicles. Here's the abstract first:

A system and method for customized music delivery to a vehicle including determining a playlist, storing the playlist on a server, selecting content corresponding to the playlist, transmitting the content to the vehicle by satellite, and storing the content in a telematics unit. 

The overall concept is that the user would be able to create a custom playlist that is stored remotely on a server, and access that playlist - via satellite - anywhere in your car. They specifically cite SDARS and give several examples of usage (including video). The integration could be with the 'telematics unit' either connected to the vehicle's satellite radio receiver, or embedded within.

It sounds like a great system. GM would be solving all the connection problem that people have had with iPods (to the point now that an iPod cord is considered a "feature" in some cars now). My only concern would be with how human's would interface with the system. Selecting a playlist while driving could be a pretty dangerous endeavor.

Unless... XM has already solved this problem.

Thanks Tim! 

SIRIUS Canada and BMW Canada have inked a long term deal that will make SIRIUS Satellite Radio receivers a factory and dealer option for BMW vehicles sold in Canada.

Starting this fall, SIRIUS Satellite Radio will be available in select Canadian BMW models bundled with a subscription to SIRIUS Canada's satellite radio service.

By 2007, all BMW models will be SIRIUS Satellite-ready.

Here's an interesting deal. XM Canada and Toyota Canada announced the signing of a multi-year agreement today, offering XM Canada in Toyota and Lexus vehicles.

Starting on August 6th, XM Canada will supply their satellite radio service to select Toyota and Lexus vehicles. 

Under the agreement, XM Canada will offer free activation plus 3-months of free satellite radio service. An additional 3-months is then matched by Toyota Canada, providing a full trial period of 6-months to the customer.
