  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:

  5. My 2001 Nissan Altima stock radio just quit working. I checked the fuse under the hood and replaced it but as soon as I plugged in the new fuse it blew. Cannot get radio working again. No kind of wiring work or radio work has been done to it. The only thing done recently was a new battery put in. Can someone please help?

  6. I replaced my daughter’s OME 2 din CD changer in her 2001 nissan Altima with a single DIN aftermarket. Why does the unit lose power when the antenna wire is unplugged (she does not have an external antenna)? Also, this is the 2nd aftermarket she has had and the tuner didn’t work for either??? CD player and IPOD connection work great. anyone?

  7. OhioFinest21, the car radio accessory switched 12v+ wire (blue wire) is used to turn on and turn off the stereo. Hope this helps. Good luck with your 2001 Nissan Altima stereo installation.

  8. Isaak, your 2001 Nissan Altima may have a factory amplifier that needs to be turned on by your after market radio. The car stereo amplifier trigger wire has to be wired up to turn on your factory amplifier. Unfortunately, we do not have this information but maybe someone from the Modified Life community can post that information here. Hope this helps. Good luck with your 2001 Nissan Altima amplifier wiring.

  11. Jason, your new car stereo will have a wire harness with tags on each wire that indicates which wire hooks up to the illumination, antenna trigger and dimmer wire. Hope this helps. Good luck with your 2001 Nissan Altima radio install.

  12. Need to clarify…..illumination, antenna trigger, and dimmer wires…..if I purchased an aftermarket stereo, where do those wires connect on the new stereo?

  13. My wife has a 2001 Altima with a 5 CD changer. There are 2 CDs in the changer ; they will not eject and the CDs will not play. A code (ERR2) is displayed when we try to eject the cds. The remainder of the audio system is fine. Can you assist us?

  14. I purchased an HD radio for my 2001 Nissan Altima. My problem is that I receive poor or no reception form the factory installed antenna. My question is, Where is the antenna located, and can an external antenna be installed? Thanks
