Just for a point of info.If you have a factory raido in which the display has gone blank,there is a quick fix.You can switch just the faceplate without changing the entire raido,which means no dealer programing. If enough members need it I'll make a DYI post.

 

Hey, Just a newbie so browsing & found your 2011 post about a faulty, blank head unit that went blank on my 2007. Dealer wants $550 new radio ! Tell me your fix.
