Hello,
I downloaded the dropbox file and was able to put it in my thumb drive. I have a Pioneer Avic-5200nex. I plugged it in and tried to go to factory default and initialize it. I kept getting an error screen that contains the photo attached. I tried activating and inactivating my Bluetooth and it still gives me this. I have no idea what it means by "please turn the power off to test Bluetooth." I don't have anything connected to Bluetooth and not sure how I can turn off the power without that screen turning off as well. I am stuck and not sure what to do.
