I should be getting audio on channel 1 of the XM receiver

I get none.

I have not yet transfered my old XM account over to this unit. But I should still get the "sign up for XM" advertisements on channel 1.

btw, go to fatwallet.com to get XM at 50% off for the year. seach for XM radio.

Make sure you have the IP bus cable in the correct jack on the XM tuner.
