I have not tried the switch myself, I just know that some phones are much better than others and that may be the culprit.
We have swapped phones and used a Service Tech's phone in her Focus with the same issues. The last time we went to the dealership they did replace the mic, but there still is quite a bit of road noise and distortion.
