Yeah, standard Single Din size, any thing will fit just fine. Check www.crutchfield.com
for a GREAT selection of stuff! I have bought quite a bit of gear from them for the mobile world. I wouldn't buy too many of their home products, because they have to recoup the cost of shipping of ginormous TV's somehow, and they do it in the price of the gear, but for mobile stuff, they can be pretty hard to beat. Great customer service too!
