My xm delphi xpress radio always reverts back to

Oct 21, 2009

- Thats all well and good...the problem is...that it just started all of a sudden. The radio holds all of it's settings and favorites. If I was listening to station "A" and turned the radio off or turned the vehicle off, then turned them both on again, the radio would be tuned to station "A". Now when I turn either the radio or vehicle off, the radio always reverts back to the preview channel. I reset the radio using it's restore to factory setting option. But it still reverts back to the preview station whenever the radio or car is turned off. Is the radio defective?
