30 feet is more than enough for my needs. I am able to plug into my car's Bose system with great results. I did know the Curve could handle music and video when I got it for business reasons. Quite a bonus. Thanks for the help.

As you can see it shows a range of 100 meters. When used inside a building you can get probably 50 meters if you are in a more open area. Once you start putting walls in between that decreases dramatically.
If you want wireless freedom the bluetooth approach is the way to go. Otherwise any system with a headphone jack can handle the BB. Gotta love that they went with the 3.5 mm jack instead of the more common 2.5 mm variety.
