how do you remove the Map button on the center console? Someone spilled Coke and now it sticks.

Use an electronic cleaner. Turn car off, use the spray while covering any other critical components. I'd press the button a few times to encourage 'spreading' of the cleaner. It should loosen up the gunk. Let it dry thoroughly (leave with windows open / let it bake in the sun) to get it nice and dry. They you should be good
