Ok Im having this same issue except I am adding an aftermarket amp and replaced my blown 8” sub with an aftermarket 8” sub. I wired my amp properly and a line out converter as stated by instructions and now i have no sound no volume numbers when turning up n down and no control over the sound (ie right left front rear) and it changed to no center channel i believe it is but regardless you cant change any of it now and the same no beep when touching controls but ive looked in behind my change thingy in fuse box and i see no numbers whatsoever (ie #59) and ive changed or looked at every fuse in that box none seem blown no burnt filaments etc . Ive installed many systems but this is getting very frustrating and im losing my patience. Im hardheaded n keep trying different things but im stymied now. Please help someone.
