Does anyone have experience with the GMOS-04? I'm recently installed it into my 2006 corvette. At first there was no sound. I ran the relay they showed in the diagram and followed all the steps and retraced everything carefully. It was right. Then I searched online and discovered I wasn't the only one with this problem. I discovered that it was a remote wire problem in the gmos-04 unit and connected the remote wire from my aftermarket unit to the car's remote wire. This supposely powers on the amp. I got the sound to work on ACC mode, but whenever I turn on the car the sound cuts out. I believe its the amp, getting too much power therefore it turns it off. I'm thinking about going getting the PAC unit instead, but before I do that, I was wondering if anyone had any suggestions how to fix the problem.
