Both the radio and the interior lighting share only one fuse; it is the 15 amp fuse located in cavity #1 of the interior fuse panel under the dash. I am not sure what lebel might be on the fuse box cover, but this is likely the blown fuse causing the problem.
Other fuses that power up the radio circuits are the 15 amp fuse in cavity 10, and the 15 amp fuse in cavity 11.
I hope this is helpful; if so, please click my accept button! If you need more assistance, please let me know. Thanks!
Here is the wiring schematic for your radio, to help in tracing down the source of the problem:
The first thing to do is to start at the radio electrical plug, to see if you have power at all of these:
Pin 1 (lt grn/ yellow); should have power at all times
pin 3 (yellow/ blk); should have power only with the key on
Pin 19 (lt bl/ red); should have power with the headlamp switch turned on
If you will check for power at these pins and let me know what you find, it will help to narrow the problem down to a particular circuit so we can continue...
