Hi mate, I had this issue 3 months ago, My car was listed as being a part of the recall / good-will fixes on their database.. it was mostly 03-04 models affected.. Honda Rockdale replaced the Head unit, which fixed all the backlight issues, no hassles either!

EXCEPT...the new unit skips CD's, as in, it jumps and won't play most of them.. don't really care as I have an Xcarlink for my iphone
