I was able to speak with someone from Pioneer that was knowledgeable about the bluetooth issue. He recommended two things to try: pushing the reset button on the nav face and if that didn't work unplugging the power for a few minutes. The reset worked for me, so now the bluetooth is operational. I guess I should have thought of that before.
A couple of interesting things I learned from Pioneer:
*there is not any bluetooth software upgrade despite the fact the unit seems to think that it could be.
*the software version often does not display even though software is installed and working fine
*you cannot reload the same version of firmware you already have on the unit. This is why I could not seem to get the SD cards to read.
*if your bluetooth ever stops working and the resets do not work, you will have to send the unit in for service. Nothing else to do at a user level.
Hope this helps someone.
