i copied this off another post hope this helps

Theres a fuse box in the trunk left side under a plastic knock out another on the passenger side near floor below the radio behind plastic knock out..another under the hood under the battery cover. They all have a place for AUX add ons.

No, but some of the stock radios have a DIN connector in the back that allows you to plug in a harness and switch that will provide the aux input. The radios are not that hard to find on EBAY, I bought one for $20. but I have not built the harness yet. There is info all over the net if you google: Altima DIN aux.

first check the aux fuse, then check to see if the clock comes on the radio, if it don't check the radio it should have fuses, check them. check the connector to the radio for power, with the key in the off position you should have 1 12vlt power with the key on you should have 2 12vlt power... if the fuses are good on the radio and you don't have any power to the connector, it could be a relay or ignition switch

Remove the 3 knobs for air system.
Remove the 2 small philip screws at bottom.
Pull bezel straight out.
Remove 4 larger philip screws on either side of radio.
Pull radio straight out.
To find out if your radio has "AUX IN", hold CD button for about 2-3 secs. If AUX appears on display your model has "AUX" connector in back. 2003 and early 2004 do not have "aux in".

You are correct. There is a fuse in the underhood fuse/relay compartment that powers up the pin. It is one of the larger fuses and should be labeled as "AUX". Also check that the power wire is connected to the AUX bolt terminal. They shipped from the factory disconnected and the cable was zip-tied to something below the fuse box.

go to coloradofans.com or purchase a pac-oem and an ab-gm12 connector if you have a rfd model radio (displays song and artist on radio) or you could purchase an expensive kit from bestbuy. I have an Isuzu i-350, always refer to it as a colorado when looking for these parts.
