  1. Hi There, I have just replaced the battery in my 2004 Mitsubishi Lancer VRX. I now need to reset the factory radio/sterio. I have a 4 digit code but when I entered it I was asked for code 2, then code 3. Is there a certain sequence that I need to key in the 4 digit code? What is best way to reset it? Cheers, Dion

  2. Hey, I’ve been searching all over for a dash kit for a 2002 mitsubishi Lancer es, I’m coming to all dead ends. Does the 2002 mitsubishi lancer even need a stereo install dash kit or did they start needing them just in the 08+ models? Thank you

  3. Amy, an automotive auxiliary input adapter will allow you to input any mp3 player or portable music player into your factory radio. This is the easiest and most cost effective way to add an audio input into your factory stereo without using an over the air FM transmitter. Here is the adapter you will need:

    If you’ve never installed car audio before, we advise you to take your car to an experienced mobile audio installer. Hope this helps. Good luck with your 2004 Mitsubishi Lancer aux input adapter installation.

  4. Hello,
