I have this same problem and I tried to re-update with the 1.0003. Two different SD card both reformatted with FAT32 and the unit will not recognize or allow me to re-install the firmware. I had updated to the latest firmware before I used the unit, so I know one of the SD cards for sure works. The bluetooth worked fine for a week, then I didn't drive the car for a while. Sometime in there the software got lost. I tried searching on the Pioneer website for the bluetooth only update with no luck. Norm_11 did you have any luck? I guess it is time to test the Pioneer help desk.
