Code for car stereo

I'd google the brand of the radio if it is an aftermarket radio and try it that way. I had to do it with my jvc radio

You can finds codes for most radios available online via a google search as Dakota said. Use year make and model of car for the search and if no luck, you may need to pull the radio and get manufacturer numbers and name off the radio.

look in the glove box on left hand side for a sticker with numbers on it thats your code
