HiCustomer welcome. I'm acramstr. And I will be assisting you today.
Did all the preset buttons work when the radio was working?
Are you sure you have the correct code? If so try disconnecting the battery for 15 min to clear all the memory and try again.
If it still does not work let me know and we can try some other things.
