Unplug negative from battery, Remove the trim carefully with a small screwdriver to access the 2 screws securing it....then pull out and unplug
(if i remember right)
I would also like add, If you start to have a problem. Take it to a pro and have them install it. Last thing you want is have something go wrong in the dash. I see it all the time.
