Been trying to get satellite radio working for like two weeks now. First replaced antenna, and that took care of the no signal. Activated a trial and can cycle through all channels and shows radio id, just never sound. Figured it must be tuner and got a sir-gm1 Sirius tuner, plugged it in and same result as the factory xm tuner, no sound even when showing stations and radio id. Any ideas? 04 sle

Turned out it was just the audio connection from xm tuner to head unit was unplugged under the steering column.
