I changed the battery on my 2012 XKR a couple of days ago, and now the SiriusXM satellite radio won't work (it just displays a white screen that says "call Sirius..."). I have tried going to the SiriusXM web site and "refreshing" the radio, but no luck.

Any suggestions ???

 

try taking terminals off the battery and touch them together then restart if you still get the screen call Sirius and let them send a signal to the car.
