i had to disconnect my battery and my radio says safe. i dont have the code so i figered out that if you hold MODE and turn it on it works for 2 minutes. so i did it all week because i didnot have time to go to get the code. anyways, every time i held MODE a number would come up on the screen and it went up 1 every time. now it is at 20 and it dosint work. do i have to get my radio recoded.
