I had the same problem twice and I fixed myself, you are right is a blown fuse and is in the fuse box that is located in the engine compartment, you have to look for a yellow 20A fuse.stand next to the driver side front tire, with the head light to your left and driver door to your right,is 3 yellow fuses near to the battery check the one on the left that is the one for your radio. On the fuse box lid is marked as RDO/IPIGN. I drive a 02 grand caravan ES, I hope this help solve your problem, driving without music is not fun at all.
