So i took the face off the radio and when I put it back on it wanted a code.
I did not know the code so I tried the basic 1 2 3 4 then 1 1 1 1 then 6 5 4 3 after that one it just changed to a wait screen and will not do anything else. Anyone know how to reset it? I tried pulling the fuse and putting it back in but it did not work.
