I have an 06 FLHX. Last week the display went blank. I went to the HD dealer today in my car and told them about it and they gave me a CD to use and update the software. I came home and read the directions and it stated that the software is not to correct problems that already exist. In the directions it is clear that the display must be working to perform the update. I tried removing the maxifuse for 10 minutes to see if the radio resets but nothing. Do I need a new radio? If not, what do I do now?
