Ok, I'll check those. Also, when I had the whole unit out but still wired to the car, when I moved the Empeg around, like up and down, the reception would get better and worse.

The Green phone wire is not used on mine, and the blue antenna power wire is not used, and is protected on the end.

I'll pull it all out again and check the wiring on the connectors.
Is that what you mean when you say the extension cable, the one that plugs into the tuner?
