Mike - We have a Silver Leaf in our 1999 Patriot. It is pretty helpful but at times has been something of a mystery for me. Last month I had the unit "flashed" at Silver Leaf in Albany, Oregon. It was a great investment for a few bucks and nicley updated things. Dale Kemper is the Service Director at Silver Leaf. He was very helpful and very knowledgeable. Dale used to work at the Factory in Bend when they built my coach and was very familiar with it. I would suggest you give him a call and chat with him. He is a nice fella and I am sure he would be happy to enlighten us. Deale can be reached at 541-967-8111. Hope that helps!!!
