The unit keeps blowing the fuse in the cars fuse box(10amp), the unit then does not work or display anything, but it still ejects the cd and takes it back in.

You have a short or the wrong amp fuse how can it eject or take it back in if the fuse is blown??? unless there is a secondary fuse somewhere is it wired into the accesory fuse it is possible it is wired into a spot that may have something else hooked in and your deck is overloading the fuse check to see that you have it so it is the only unit wired to a fuse
