How to Add an Auxiliary Input to a Nissan Radio


The popularity of personal audio MP3 players has made the need for an auxiliary input on a factory Nissan radio is more pressing than ever. Most premium Nissan stereos come equipped with a compact changer, or at least a port on the radio to accommodate a changer's plug. Inventive aftermarket equipment providers now make adapters to connect to the changer's port to use with auxiliary equipment.

Things You'll Need

  • Aftermarket CD changer adapter
  • Access the back of the Nissan's radio. Locate and unplug the single wiring harness in the lower, center portion of the radio, if a changer is present. Out of the three harnesses on the radio, this will have the fewest wires. If a changer is not present, find the black, plastic adhesive cover blocking the changer's port and remove it.

  • Slide the harness from the auxiliary input adapter into the port previously occupied by the changer's harness. If the adapter allows for it, plug the the changer's harness into the adapter.

  • Slide the audio cables for the auxiliary source into the "In" RCA jacks on the adapter.

Tips & Warnings

  • Some adapters make all connections on the harness supplied with the adapter. If so, simply disconnect the wire and power harnesses on the back of the radio. Replace these with the matching harness plugs on the aftermarket adapter. Plug the vehicle's harness plugs into the matching ports on the adapter's harness.
