Howdy, the Jensen outside wall radio in my Winnebago Mini also turns on by itself. Have heard it before from other winni/Jensen owners. I am living with it because it gets disconnected when my main power switch is off. The dash radio was also a Jensen (RV radio with integrated weather radio) I scrapped that because the CD player did not work. Sad to give up the weather radio function because that was cool. Got a stock rebuilt radio with 3mm input jack. Very good quality rebuild unit.... Got it from Factoryradio.com . Very good customer service to make sure you get the right one.
