Looks like I lost my first reply to this thread. Try resetting the radio. Reset button located near bottom left front of faceplate. Next to the 'Aux' input. Press with tip of pen or straightened paperclip. Hold for 6+ seconds. This is with the ignition off.
The blue light (or white light if in a 'fault' state) behind the power button will go out after resetting.
Turn on/start RV and power up the radio. It may need to be restarted a couple of times (basically rebooting itself). This is a 'soft' reset/reboot. Preferred method is a hard reboot accomplished the same way but with all power removed from the radio rather than just the ignition off. However a soft reboot solved the problem I was having.
