#99082 Its one of your fuses.
Most likely the 7.5Amp fuse under the hood is blown, its called the ECU Backup fuse, also powers Radio and Clock Memory.

#99137 Check and see whether he wired the radio's constant power to accessory.

Radios have a red and a yellow power input. Yellow is constant. Red is accessory (loses power with key off).

The Civic's constant is white/blue and the accessory is yel/red. And yes the clock, cig lighter, and radio share the same circuit.

If you don't feel comfortable then take it to best buy. I used to fix these kinds of problems all the time when I worked there.
