Hi, can you guys please help me out here? I am planning to get mp3 player+harness (Sony In-Dash Player. (SON CDXGT310)) for my 92 accord. but i am not able to take the factory installed cassette player out from my car. also, do I need a custom installation kit for this new mp3 player? or it will fit in my car?. Someone plz help
