I did the first time. After I got the message, I went back to the camper, set the tilt to manual and ran it all the way out. Then turned off the ignition (killing the radio).
Still got the message. So I went back, put the SD card back in, turned it on (started normally). Then turned the radio itself off with the power button on the radio, and then shut everything down.
Still getting the error message.
Oddly, if I tell it to ignore this and continue, it tells me an OS update is required before I can do anything. It puts it on there, and tells me to go stick it back in the radio, and turn it on, let it load, and then turn it back off before proceeding. Did that. Brought the SD card back, and it doesn't recognize that the OS update has been applied, and wants to apply it again. I'm stuck in a loop here.
I'll be on the phone with Winnedbago and River Park in the morning for sure!
