Car stereo installation supplier Metra have a universal "pocket" that's intended for use in double-DIN vehicles like Toyotas, Subarus, and recent Volvos. The part is shown about halfway down http:// http://www.tune-town.com/Installation/detail.asp?subcat=toyota . I toss the pocket in the empty sled above a Blaupunkt head in my Volvo, and it looks as stock as I can expect.
