Do I need a code to reset my radio? My car wouldn't start so I had the battery jumped

Hello, check for blown fuses. A power surge from the jump start could have blown one or more fuses. You could also press and hold the power button if you verify all fuses are good and see if the radio comes back on that way too. If neither works and you testing wiring to the radio and find out there is power there, then the audio unit itself may have an internal concern, and yes - could be due to the jump start. www.repairpal.com/repair-shops A link there to find shops near you that can help.
