The stereo does not have aux inputs but if your car is prewired for satellite and you have a SAT button on your radio you may be able to add them without taking apart the dash and buying expensive adapters. Your car must be prewired for satellite to do this, if your not sure do a search and find the vin break to see if it is. I dont know if this will work for all years but I did this on my 03 sedan and it works perfect. However, you wont be able to use your satellite tuner without unpluging and reconnecting wires.
(1)You need to buy some male and female rca connectors. These are the exact ones I bought. http://www.radioshack.com/product/in...ab=accessories They make a solderless but I prefer soldering.
(2)Locate the sat harness going from the radio to the trunk. On my sedan it runs front to rear along the passengers side. You can put your rca jacks into the harness at any point, I found that the right rear passenger area makes it very easy to run extension cables/jacks to the console. Open right rear door, remove the lower trim piece between the carpet and the weatherstrip. Remove the lower center pillar trim. Thats the piece at the bottom between the front and rear doors, pull from the bottom and work your way upwards. Now you can pull the carpet back enough to get to the harness.
(3)The harness at this point looks like 2 white sheathed cat5 cables and a some colored wires you dont use. One of the white sheathed cables is slightly bigger than the other, using a razor or sharp knife carefully trim back the white sheathing on the slightly larger cable to expose the inside wires. If youve trimmed back the correct white cable you will see 1-black,1-white,1-red,1-green and a naked ground wire. If you dont see these colors put some electrical tape over your cuts and try the other white cable.
(4)With the correct wires located now its time to cut the black, white, red and green wire. The black wire is right+pos, the white is right-neg, the red is left+pos and the green is left-neg. Install the female rca connectors on the cut side of harness going to your radio and the male going to your trunk. The male plug will only be used if you decide to use the sat tuner or return to "stock." Use the red rca for the right side and the black for the left. If you've never used these rca connectors before, the ground is the outer most terminal and the positive is more centered. Its also best to use a small piece of electrical tape and wrap around your connections.
(5)The aux input is done! Press the SAT buton on your radio, connect your ipod or other source and try it out. Run an extension cable to your console put the trim pieces back together and enjoy.


In picture 2 the cable you want to cut into looks more gray. I didnt notice at the time but my camera flash did.

Picture 3 shows how I ran my extension cable. Remove ashtray, remove the 1 screw on the right side of console. I used a wire snake to go through the ashtray opening, under the carpet and it came out by the input. A coat hanger should work fine. As you can see in the pictures, my extension gets to the console and is connected to a rca-3.5 mini cable thats routed inside of the console compartment.

Picture 4 shows the male plugs which are not going to be used unless you want to use the satellite reciever.

 

No its not fm crapulated. It has cd quality. The radio thinks its playing a satellite preview channel. This over rides the audio signal with an aux source. Some threads say this is impossible due to line level voltage. That is not correct, the satillite tuner is a component which must work with the radio and the amp in order to be heard.

 

I dont know if this would work if you dont have a sat tuner. My car has a xm tuner thats not activated which allows it to play the preview channel. Those of you that are prewired but dont have a sat tuner, what happens when you press SAT on your radio? If it ignors you and continues playing fm/am/cd I dont think this will work. If thats an issue let me know I can probably figure out the commucations between the radio and sat reciever and come up with a simple way to make it work. Going snowboarding in the morning be back next week.

 

very nice. might be confusing for some but i'm totally with you. might would of tried this myself had i know before my PAC. good work!

you should post up a new thread here and in the DIY section with this.

 

my g doesnt even respond when i push the sat button and i think that would be a big broblem, unless you think the radio believes the input is a satelite signal

 

do you have something hooked up like a sat or PAC? i never pressed mine before i did - but i wouldn't be surprised if it doesn't do anything unless you have an input for it.

 

it doesn't respond because you don't have anything connected to it
If you don't have a cassette in the cassette deck does it respond? (I can't believe they still put those in cars :S) Same deal. once you get an interface module - sirius or other aux input device - you'll have it respond

 

anyone know where the sat wires are in the trunk of the 04 coupe?

 

if you get the factory sat adapter it plugs right in

 

they have a install tutorial PDF or two on EverythingG35.com for the Nissan factory ipod kit - it highlights how to find that wire in the trunk. it should have your answer. go check it out...

 

When I get a chance Ill if I can figure something out on this.

 

Well i have been trying to finish this instal but the coupe is wired much differently than the sedan because the wires run driver side. The problem ive encountered is that the radio does not respond to the sat button. I think that you need a satellite reciever because it connects to the radio through different cables to control its functions/power and the audio connection cables are seperate. This install is bypassing the audio input but requires the complete circut from the reciever to trick the radio.

 

interesting...i might have to check this out...i dont like using my cassett adapter for my ipod...

 

^ or you could save all the headache and just buy a plug-and-play PAC for $65

 

Where can I find this Plug-and-play PAC? I have the Bose radio
