Can't get car talk in the car!

Two days ago, my husband borrowed my Saab 9 3 convertible. When he got home, he complained that none of the admittedly nonintuitive preprogrammed faves worked on the radio, only random XM channels. No AM or FM at all. Any ideas?

Reprogram the radio and see if it happens again. But don’t let Hubby have it in the meantime. I assume that other than the buttons, the radio works.

I don’t think I can reprogram, because none of the radio buttons work. All we get is XM, and we only get that by going through the PTY button to select program type then scanning up or down.
