Question

I am trying to hookup an xm radio through the cassette player in my 96 maxima. It works for about a minute and then the cassette player ejects the tape. Do you guys have any suggestions? Is there any other way to hookup a xm radio or than the cassette adapter? My stereo doesn't appear to have any other inputs.
