well i finally got my FD back, its been gone since July. and everything works but my radio and my temp gauge on my dash. the radio is a weird problem when i put the key in the antena will go up and come back down but the head unit will not turn on. i checked the wire and fuse running to it and its fine so im lost. then my temp gauge while driving today it shot up above the hot symbol and i stated to freak out then looked at the power fc and it was fine. im not sure why all of a sudden it would do that. if anyone one has any input please feel free to post
