Blow a fuse or something else?

Hi everyone,

I recently added a stealth radio on my 2007 prius. I forgot to add the resistor and the radio worked for a second, and then shut off. I added the resistor and things started working again, but not the radio. I thought it might be the fuse in the new radio or the radio itself that broke, but neither is the case.

I also noticed that when I put the fob in the ignition slot and open the door, it no longer beeps at me. Also, the light doesn't come up on the dashboard saying that a door isn't open. However, it does come up when the car is turned on.

Actually, no lights work inside when the car is turned off. Is this just a fuse problem, or did I do something else to it?

Thanks!
