I had the same thing happen...only it was my clock, climate control, and cigarette lighter that stopped working. I took it to my dealer and they found a short behind the dashboard which caused the clock fuse to blow... they fixed it for around $86.00. Weird things can also happen if your sunvisor wires short out. Check the wiring at the end of the sunvisor (where it connects to the car) and see if the wires are frayed. There are fixes on the forums here.
