ive had this headunit for about 6 months now and it has been working great until today when it all of a sudden turned off and wont turn on again. i looked on the manual and the only thing i found is that the fuse might be blown. how do i go about checking the fuse on the headunit, and if its not the fuse, what else could it be. any help would be appreciated, thanks

 

You have to take the headunit out, and on the back there is a fuse you will see.
