FM Direct Connect stopped working... Everything was working fine on Friday morning. On Friday afternoon, I plugged everything in and it lit up...but no sound. I get the 3 bars of service in the car. The radio works in the SUBX1 box. The guy from TSS Radio suggested that I should hear a faint click when the FM-MOD is activated by the radio. I didn't hear the click, but then again, I don't know what the click sounds like. Any ideas here?
