Radio not working

Right after I put a DC/AC converter into a cigarette lighter, my radio and clock went dead (radio does not turn on), as well as other cigarett lighter adapter that was powering my GPS. No juice there.
I'm suspecting a fuse, but cant' figure out where it is, I looked in the fuse box under the hood but they are not labeled.

Thank you for your help.

While driving the radio stopped working. I can not find the fuse so I am unable to tell if the radio is getting power. I am not sure if the radio is bad or I have a blown fuse. I have checked both fuse boxes and all fuses are good but none state they are for the radio. All other system work, just the radio is not working. Can you tell me where the fuse is and how to check to see if there is elec power going to the radio.

My car stereo froze up and would not let me change the station, am/fm, cd, or adjust the volume, yet it was still playing the radio station it froze on. After turning off the car the sound stopped but the LCD screen on the radio remained on even after removing the key.

We have disconnected the battery which shut off the radios LCD display and the reconnected the battery and restarted the car. No the radio will not come on at all. We have checked all the fuses and they aren't blown. All of the surrounding things in the dash work. Like the cigarette lighters but the stereo will not turn on.

I am completely confused as to why it would work and then now not work. Maybe the stereo is just shot. I am just wondering if there are any other possibilities that could cause this.

Thanks

I have checked the fuses under hood and drivers side all seem fine

If this fuse is bad will it affect the power antennae as well?

Will I have to remove radio to replace fuse or is it possible to replace in place?

Found the fuse! It was blown, replaced it and my stereo works again. Thank You soooo much
