In a 2003 Nissan Xterra, the fuse for the SRS (Supplemental Restraint System) airbags is located in the interior fuse box. This fuse box is typically found on the driver's side, near the dashboard. To access it, you may need to remove a cover. Consult the owner's manual for the exact fuse designation and location for the SRS system.
The 2003 Nissan Frontier radio fuse location is listed on the inside cover of the fuse box. The radio fuse should be the very top fuse in the second role of fuses.

You can get a copy of the fuse box diagram chart for the 2003 Nissan Sentra online at places like Modified Life and Car Care Kiosk. You can also find these diagrams on the inside of the fuse box cover or in the Chilton's manual for that year and model of vehicle.
Not positive but I think the newer models (with airbags) use the same fuse for horn and airbag. If you don't have airbags I don't think they used a fuse, it may just be wired directly.
