aight check it. my mother has a 04 jeep wrangler. your radio stopped working like last week. and i noticed the other day when i was driving it if you hit a bump it come one for a lil while and ithen it will go off again. what could be causing this?

 

Had a problem today just like that. Not sure if it's the same thing, cuz my cars torn apart and my radio's just sitting on the floor where my console used to be, but have you checked the grounding? I shorted something on mine and for some reason when I touched it (the radio itself) to a ground, it would work again.
