Corolla Radio does not work

I have a 2003 Corolla and the radio quit working. I had a problem starting the car becuase the temp was below zero. I jumped started the Corolla off of my other car and since then the radio will not work.

I do not think it is the fuse in the engine compartment or behind the coin holder in the passenger compartment. All other light and gauges that are on the same fuse still work (clock and power outlet still work). Does anyone have any suggestion on where I should look for the problem? Is there a fuse on the power line to the radio? If so how do I pull the radio out to check.

I would appreiate any advice -- I do not want to have to replace the radio.
