Just recently did a 2 day trip to FL driving the X3. (first time in about 15 years or so).

Entire MP3 collection is on the HD of the CarPC. Listened to a variety of music.

Only occasionally (for news) listened to Sirius.

Personally rarely listen to commercial radio (occasionally BBC news).

The CarPC also offers DiVx movies and GPS (alternate).

It also offers another means of connecting a rear view cam. Application I'm using has both cam and sensors features.
