Sure... all of them The only type of 1 DIN Alpine HU's that don't fit, are the ones that have a fold out screen of some kind. But all of them that just have a regular fold down faceplate for CD disk insert, those all fit.

 

i can also give you a picture, actually i really looked last night when i drove my car
it does come down and hit the cover when its down a tad, but it has some room in it to tilt so it just slowly rides the bottom of the cover and bends some more in a good way
trust theres enough flex in it, its not breaking anything it is there to be adjustable, i can take a pic but basically teh cover rests on teh bottom once fully open
