  1. Lethal, it would be hard to say what is causing your 2001 Nissan Altima auxiliary audio input to stop working. It could be that the input itself is faulty or a wire is loose on the inside from wear and tear. It would cost a pretty penny to get it diagnosed and repaired by an experienced mobile audio installer. We suggest you install an aftermarket auxiliary input adapter. This aux input adapter will allow you to input any mp3 player, portable music player, Apple iPod or Apple iPhone into your factory stereo. This is the most cost effective and easiest way to add an audio input into your factory radio. Here is the adapter you will need:

  6. I replaced my daughter’s OME 2 din CD changer in her 2001 nissan Altima with a single DIN aftermarket.
