I just bought a Civic EX. There is an aftermarket radio in it and the dome light doesn't work (you can turn it on with the switch but not by opening doors), didn't come with a remote either. I am assuming that the previous owner screwed up the dome light and remote entry by replacing the factory radio. I want to restore the car so the keyless entry and domelight work, what are my options? Can I use later model factory radios with my '98? Are there any wiring tricks when reinstalling a factory radio? TIA
