Curious, anyone else have this strange problem of AM/FM radio not working occasionally, at random, will stop, then may work again a day or so later as if a loose connection somewhere, but it is not a power issue for CD works fine, so my question is, are these two separate units as it appears in pictures, so one has no impact on the other? I have found no solution or even same symptom talked about on others forums, so curious if anyone has an answer to this. Can I just change AM/FM radio, or does it need programming like all other modules usually do when replaced.
