ok so hears the thing. my radio turns on wen the truck is off. its been draining my battery every time it does this so i cant drive to school! i checked last night turned it on it ran fine i turned it off, checked the radio and every thing was off. i was happy went inside. i came bak in the morning to start it and the battery was completly dead! the radio was off. im stumped. i come bak from school and the radio is on! i cant turn it off! everytime the radio comes on the keys r out. im thining of getting a new stereo to hopefully fix this but has any1 had this problem and wat did they do. thanks

 

Is it the stock radio or aftermarket? If it's the stock radio then I have no clue. As far as aftermarket goes, sounds like your accessory wire (think that's right) has come unhooked or is about to. That's what makes the radio come on. Kind of like hooking up an amp without a good remote lead, thus making it stay on constantly.
