thats the only thing stopping me from doing one of those systems, the deng HU space. That thing takes up nearly a foot! I haven't seen any aftermarket HU's that look fitting after replacing it. A 7" HU leaves you with 2.5" of space on each side. I think there are some bezels at www.mybimmer.net if you don't see X5 displayed then email him. I think I'm going to wait until I can find some kind of wide screen model -__^
