The other day I drove the beast for the first time in 3 weeks. She's kept safe and dry inside my garage and always have been since day one. So while driving I noticed the radio screen was fuzzy looking. At first I thought I was having vision problems until I saw it was clear in a few areas. The radio worked fine and I continued to my destination about 45 minutes away. By the time I got there the screen had cleared up completely and no residue was visible inside. It was a muggy/high humitity day and in the upper 90's. But I thought the radio was a sealed unit that prevents that from happening. Anybody have words of wisdom????????
