Narrative:

We were originally told to expect runway 2C at bna. Approach then told us to expect runway 2R. We were then told to intercept runway 2R on a 340 degree heading. The first officer was identing frequencys and I turned to 340 degree heading. My CDI was deflected left. Approach then asked us to turn back to 040 degrees to reintercept runway 2R localizer. We complied and relayed back that we thought the captain's CDI was indicating improperly. As it turns out, I had failed to turn off the radial/navigation switch. I then turned it off, intercepted runway 2R localizer and landed visually without incident. Supplemental information from acn 478680: we told ATC we thought we had a receiver problem.
