My battery was jumped backwards in my 08 f150, and now the stereo won't work. Everything else works fine. Checked fuse under the dash it's good. Any suggestions?
have the same problem?

There's two fuses; one for the switched 12 volts and one for the memory circuit. The memory circuit is typically tied in with something else that's always hot, like the interior lights, horn, or cigarette lighter. On a lot of newer cars the radio needs a turn-on signal from the Body Computer. Computers don't like reverse polarity from jumper cables hooked up backward, but it is very unlikely that computer could have gotten damaged and the radio is the only thing affected.
