hey, peeps i just bought a rx8 and the old owner told me he blew the head unit by installing a aux. cord to the stock stereo so now i can't turn the ace on or defrosters and the hazard lights, but the stereo still plays but i cant see what station I'm listing to or what song # is the cd playing i wanted to see if something like this has ever happen to someone and if so did the head unit had to be replace or can it be repair

 

I have read someone had a similar problem but can't seem to find it right now. You should check all the cabin fuses to see I they are fine. Usually, the fuse would burn before the equipment is damaged.

 

He tap the wrong line and blew it up. what a moron.

but it sounds like he blew something else.

without seeing the wiring it's really hard to tell. like abrankhalid said, check the fuse first.
