Just a guess remove the battery cable and reconnect after a minute but first check all your fuses

Get a paper clip and find the reset hole, providing you have power to both leads behind unit.

Ps, make sure the use,store is on.

Well is your use/store switch on......maybe something changed with newer coaches, but usually dash radios are powered from House batteries not Coach battery. If there is power to the radio then try some of the other common reset techniques.

Check your 50 and 100 amp breakers. One under hood near battery is probably the culprit.
