When i took mine out i simply managed to get my fingers between the headliner and the back (rear of the car) side of the console. From their i pushed forward and pulled down and the plastic flexes a little bit and you should be able to get the backside out and then just pull the entire unit down enough to unhook the 3 plugs for the homelink transmitter, sunroof switch, and overhead lights. It isn't to hard. i experimented with LED'* in my overhead lights and had to take the thing down about 5 times before ditching the idea completely.
