Hi,
I was getting "E20" error's on my monsoon stereo when I tried to play CD's on my 99 Firebird. "E20" is apparently an internal focus problem. I decided that it was probably unfixable and decided to replace the unit with another. I bought one off of E-bay which the seller claimed worked perfectly. I just installed it and guess what? I get the same "E20" error with the replacement unit. Could I be having a problem with the wiring? Or do I just have bad luck with getting another failed unit?
Any help would be appreciated.
BG.
