I have a honda accord ex 2001 model. I have no experience or any knowledge of cars. However, my cd changer recently got jammed and my stereo system is the default one that comes with the car so it's old. I want something compatible with ipod/android anyways so I went to walmart and bought a stero system. In addition, I bought the tool kit, the install kit, and the stereo connector. Is that all I need? I may need help from any people with knowledge in this.
