After jump strart, radio is not working. All fuses seem to be ok? What could be wrong?

Could be the alarm system, the key proximity sensor, etc.
But start with the easy stuff first, like the neutral safety switch, etc.
If it does not start in park, try neutral.
To see if the starter is ok, jump the large terminal at the solenoid, to the small solenoid energizing push on terminal. (make sure in park or neutral, and parking break engaged!)
It is possible to simply wire a momentary contact switch and bypass all the alarm stuff.

If my memory serves me, this vehicle has a Body Control Module fitted which takes care of these and many more functions. By connecting the jumper cables incorrectly, this module may have been damaged and will need to be checked and or repaired by qualified persons. The radio may also have been damaged by incorrect jumper cable connection . To be honest, incorrect cable connections can destroy most electronic devices in the blink of an eye and can be very expensive to replace damaged parts. My advice would be to take the vehicle to a qualified auto electrician and have all the vehicles systems checked including ABS brake systems, Airbag systems etc.

check your wires and the fuse to the radio. there is a fuse inside the radlo

You need a code to enable your radio. Happens every time the battery is dead or disconnected. Contact a Saturn rep.

TWO FUSES ON THIS SYETEM ONE IS LOCATED ON THE BACK OF THE RADIO AND ONE IN THE FUSE BOX CHECK BOTH IF OK CHECK ALL FEEDS AT RADIO IF OK WILL WANT NEW SET AS ITS BEEN SPIKED BY JUMP START

Hi, check the fuse box for a blown fuse in the radio slot. sometimes during jumps, this fuse will blow.

battery is dead... have the battery and alternator tested for functionality

Sent you two .pdfs this morning; they should help you out. Thanks for choosing FixYa!

I believe the Kia has 2 fuses for the radio, one in the cabin, and one in the engine compartment. Check them both. If they are good, your radio is toast.

Sounds like you fried the board. Best way to check a fuse is pull out and do a continuity check.

This is why most people these days don't stop on the road and jump strart another car. There are too many electronics onboad, if you MUST jump start then the best way is to put the Negative terminal on a piece of metal ; like the motor or chassi to avoid Elect Interference and short a circuit board.
