Sorry for delay guys on update. The radio was bad and out of nowhere Thor rep called me to see how I made out with my shower draining problem. He stated he had worked with my repair techs on fixing that problem and so I explained problem with radio. He listened to me and told me to send it in and it would be checked and if bad replaced at no charge. It was out of warranty by one month but he covered the deductible to fix it.
So I am saying THANK YOU THOR they did step up on this one.
