I just bought and installed an XM adapter for my 04 tundra, the factory radio has the cassette and above the panel it has the 6 cd changer, jbl i think. My problem is the cassette adapter that transmits the xm signal to the radio makes the auto reverse constantly keep reversing on the cassette player, XM says that some models have a way of disabeling that feature. Please help in telling me how to do this.
