Rick (above post) can fix some of the original systems but if you want to upgrade I make a weatherized touch screen system that emulates all original functions plus much more. Depending on options, it is about the same price as getting the original equipment fixed. My system is made with off-the-shelf parts so long term reliability is not an issue. I have had my system running for over four years. pete@precisioncue.com or 678-725-5640
