TO see if the fuse has blown, you'll need to fund the fuse panel it's located in. The radio fuse is normally in the panel inside the car, below the dashboard near the drivers leg left leg just infront of the door. It's probaby just above the hood release. On the back of the cover to the fuse panel (it slides off) there is a diagram of the fuses. Locatee the radio fuse and remove it. To do this you can use a pair of pliers, but it's better ot use a fuse puller. Inside the fuse panel in the engine campartment there is a fuse puller tool. It's a little white, yellow or green plastic tool.

The fuse has 2 metal prongs and a transparents plastic body. You can see insince the middle of the plastic body that there is a thin metal wire. IF the wire is continous and unbroken (it's normally curved or wavy) it's good. If in the middle the wire has melted and there is a gap, the fuse is blown. You can replace it with a fuse of the same size and current rating (usually the same color). Spares are located in the fuse panel in the engine compartment, or you can buy them at the Home Depot electrical department.

I have a 1996 camry and the battery got replaced and now the radio says SEC and I dont have the code to reset it - how do I get it?
