Is it possible to change the radio on the civic lx for the touch screen radio of an ex? Will it be plug and play, or will it be difficult? I understand I would have to get a dash kit. Would I also need wiring harness? I would like to keep the steering wheel controls. And if so, is this a good idea or should I just go with an aftermarket unit? My goal is to have gps. I was going to use the cable that honda sells and download the app. And also to add head rest monitors. To play movies for kids. I appreciate all input. I am new to the site and just bought the civic. Been a fan of the car for years and just was able to get my first one. I've looked around a bit, but did not see any thing that resembled my question.
