The b&o sound is std on limited. The limited has std 20in rims and that setup does not have ccd. To get ccd, you can get the 302 pkg but you also have to bundle the wheels which you dont want. The 302a pkg is a fully loaded expy without the nice interior touches. You get all tech, all features, ccd, and all opts features are available to add. With the plat, your paying for massage seats, noise cancellation and nicer interior leather as well as cosmetic add-ons. The platinum is a nice piece, however be mindful, though its still a bargain for the content, the nav for about 5k more will give the same feature with a far better interior. I didnt want the 22in rims either, but ccd Does make the ride better. If i could do it again, id get a 302 just for the camera, ccd, and led headlights, my wife likes the plat because the massage seats are incredible.
