Unbelievable. After 3 calls to Xfinity...they did not know what to do, let alone help me.
The code your suggested 10810 worked perfectly.
It was not listed as one of the SONY codes on their instruction and programming sheet , either!
Thanks so much. You made my day.
Thank goodness for the posting of the code 10810. Had been similarly frustrated by the list in the XR2 manual and on the Xfinity website. The 10810 code worked for my Sony, and I am now fully set up.
