I cannot seem to find a post about this issue. Occasionally when I start my car the screen on my radio will glitch. It is not a touch screen. Sometimes it looks completely normal and other times it shows up about halfway. This has started in the past few months and is getting to be more regular now.No other functions like radio or cd are affected by this. Just the screen. Is there any solutions for this? Also is there updates for 2013 base sync systems and where are those found?
