Check power to the radio - Fuse 4 (5A) and Fuse 5 (10A) on the left component panel in the cabin. Fuse 10 (10A) that protects the antenna circuit is located in the right rear fuse panel in the luggage compartment.
If fuses are good, the next step would be to remove the radio to check connections - we can help you with that procedure as well. Let us know.
Let me know if this helps:
There should be one fuse panel each behind left and right side of dash.
