Hi, Hope the combine knowledge of the forum can help me out on this one. Removed the stereo in my S3 to get access to the cup holder. Re-fitted the stereo and it wouldn't work at all, this turned out to be a blown fuse. Re-fitted the stereo again and it will turn on and shows "SAFE" on the screen all good so far, problem is that when I hold the buttons to enter the code nothing happens. I've held them for a short time with no change and also a long time again with no change. Anyone have an idea about A) Whats wrong and B) How to resolve it? Thanks in advance for any help.
