Hi tr10av and rollerdj,
Not sure if you will see this post since it is several months old now, but I just started the process of replacing my HU and I have run into the EXACT same problem w/ my '02 Sentra. The opening in the dash kit is too small. I can get the face of the HU to just barely fit through the opening from the inside, but then the face can't flip down like it is supposed to. The pic you posted above on photobucket is no longer showing, so I can't see if my kit is correct or not. Tr10av, can you let me know how you eventually solved your problem? Did you have to cut the hole a little bigger or did you figure out another way to make it work? Any suggestions, photos, etc. would be great. Thanks in advance!
