Well, I've successfully installed an OS456lite in my 2006. I tried, but couldn't find a used "full" board. So yesterday, I tried the demos of Radio Max and Scan-Star. So far, I like the Scan-Star better. The Radio-Max demo quit before I was comfortable using it. And the Scan-Star is allowing for a longer learning curve before I have to make a purchase. Any software suggestions from the group? -Robert
