Is there continuity?

YES-Substitute a known-good XM receiver, then reconnect all connector and recheck. If the symptom/indication goes away, replace the original XM receiver. If symptom/indication is still present, replace the navigation unit (see page 23-140) (with navigation) or audio unit (without navigation). If the symptom/ indication is still present, replace the audio disc changer.

NO-Replace the affected shield harness between navigation unit (with navigation) or audio unit (without navigation) and XM receiver.

XM radio preset memory is lost

NOTE: If you can only tune to channels 000, 001,174, and 247, make sure the audio unit is set to the channel mode (see owner's manual). If it is set to channel mode, call XM satellite radio customer support, and check the account activation status.
