there is an ipd/m fuse box behind the battery of my 2004 infiniti g35 sedan. I blew a fuse and couldn't find it.

I would suggest contacting a dealership service dept. with your VIN number in hand, and ask if the circuit board has been replaced. Even if it has, It will still more than likely be the problem. It's either that or the radio
