'94 antenna troubles

Howdy folks,

I recently installed an MP3 deck in my 94 Bonny SSEI, and since then the power antenna will not work and I have no AM/FM. It doesn't sound like the antenna motor is running at all.

I checked the fuse panel under the steering wheel and under the hood, but I couldn't find a fuse related to the antenna (if there is one...I don't have an owner's manual :). Any ideas what might be causing this? Thanks

My power antennae is on the same fuse as chime , lighter , radio and antennae , if it is shot you can get them cheap at the wreckers.
