i just gof my old mom's car which is a 96 kia sephia n I have no code and we've technically had it for a long time even tho used when i turn on the car the radio flashes a station number but no audio plays
if i turn the knob numbers flash on the screen and ascend (assuming thats the volume) but still no audio
when i turn it off and back on the display says HOLD
can anyone help, is there a code i need to put in?
