Radio on 1995 Honda Odyssey

My car went to the shop with a working radio. Now it isn't working. I assume it's a fuse and nothing they actually did and want to attempt to fix it myself but I can only find one fuse box and it isn't labeled in any way. I purchased this used and it didn't come with a manual. Does anyone know where the fuse boxes are and which ones I should check. I read somewhere #9 and #11 but like I said my one box I can find isn't labeled.

my radio stopped working yesterday. i cahnged the fuse on the passenger's side down near the floor. little panel down there. the radio still doesn't work
Does the radio say "CODE" on the face, or "ERROR"?

If so, the anti-theft code needs to be entered, as the battery probably got disconnected.
