How do you set Hyundai elantra radio code 2005?

To set the radio code for a 2005 Hyundai Elantra, first ensure the vehicle is in the "On" or "Run" position without starting the engine. If the radio displays "CODE," enter the four-digit code using the preset buttons (1-6) on the radio. After entering the correct code, press the "AM/FM" or "Enter" button to confirm. If you don't have the code, you may need to consult your owner's manual or contact a Hyundai dealer for assistance.
