The Sirius starmate's built in FM modulator isn't cutting it any more. We got an inline antenna adaptor from sirius but the in/out for the antenna doesn't seem to fit my 2007s antenna end. After pulling the dash apart, I noticed another connector in the antenna wiring just below the glove box. Where is the best place to get an adaptor for the Sirius inline adaptor to attach to the Mustang antenna or does someone sell the correct sized inline FM adaptor? Thanks.
