I have a retrofit radio developed by Williams Electronics (Garland Tx) that has performed well over the past two years since installation. Every so often the unit goes dark and loses all of its settings. It seems to happen after I touch the unit. Maybe it's due to static electricity from my finger or something. Anyone else experiencing this problem and have a solution? The unit is properly grounded. I have not contacted Clarion or Williams Electronics yet to ask about it yet.
