Metra kit
 

here you go guys, it the best video, and i was half asleep lol Metra kit rx8 - YouTube

Chase Geigero on risk rotors help me out "This picture is of my Metra kit in mine. All you have to do is hold the button to change the AC vents (top only, floor only, defog, ect) until it blinks, then it will go through multiple options, then just release when it gets to "Text". Then you change it using the other buttons"

You know..... it tells you how to do this quite clearly in Metra's manual.

When all else fails, RTFM.

boo i got mine used!!
didn't come with the instructions.
