need help with a cd changer problem

I installed a OEM 6-Disk cd changer in the trunk of my '98 zx2 and it worked for about two days than after I hit a pot hole it quit. When I hit the CD/Tape button on the head unit it says "no dj" the same thing it said before I installed it. The changer wont even spit out the magazine so I can get my cd's. Does anyone have any ideas? I tried to see if it was a fuse but I didn't find a blown fuse. Does anyone know what fuse is for the cd changer. Any help would be greatly appreciated.

no D/J means it either cant find the cartrige or the changer, check to see if all the wireing is ok
