Has anybody replaced their map light assembly? I have a 2010 titan (heavy metal edition) and the panel that holds the switch for my rear window has decided to become brittle and has completely crumbled apart. My local nissan dealer has told me that I need to replace the entire map light assembly. The part # for the assembly is 26430 and it comes in 2 versions... one for a sunroof and one without a sunroof. The problem that is that neither version matches the one in my titan. Any ideas??
