Yes you need to drill a hole in the bumper but not in the body. Just a little hole in the plastic for the cables and screws

this video is from 3 years ago. usualy it is easy to install a car stereo. you have red, black, yellow that are the same color. then the speakers are sets of 2 in the same color that one got a line on it so you have green and green with a line. that is the speakers. connect all the sets and you are done. just disconnect the battery before you start

yes. you have a wire to connect to the reverse light, this is how it knows you are going back

Thanks
