So my radio got locked up. And so i purchased a new one from ECS. Yes i tried the code six times so the thing got locked for good. But now i have all the connectors connected int in yet. i have all the connectors to the new one but im getting no sound. I havent pushed the unit all the way back cause i wanted to check it first. Anyone know if the radio has to be pushed in all the way in order to get sound? maybe like a ground? someone help, ive been driving without sound for like 2 weeks. HELP!
