I searched a bit, but found no answers.

I notice the 2007/8/9 SE's came with a factory aux input in place of one of the 12v's.

I guess my question would be, what is different in the wiring that would prevent installing Nissan p/n [28023] in a 2005/6 with the RF stereo? Is there no port in the rear of the head unit for this input, or does it use the same input port as the "factory" ipod interface?

I am surprised by the lack of info on this anywhere, as it seems like a very easy way to get an Aux input in a factory radio. Or maybe i'm just retarded and am missing something that is glaring. Either way, any help is appreciated.

Hi KillerB!

That is funny that you had this question as I had the same one so that I could hook up my blackberry storm in my 06 SE Xterra. I just sent off an e-mail to Jeff at Fort Pierce Nissan of Florida as he has been good at getting to the bottom of these questions for me. I would love to see a picture of the cable that connects to the back of the audio input on an 07 and see if it plugs directly into the 12 pin connector at the back of the Rocksford Fosgate system. So far it appears to me that we would need the following as per the diagram that you listed above: 1. Xterra Jack--Audio 28023 (28023-N50001) and 2. Feeder Antenna 28241N (28243-N50001). However, this whole project hinges on if that Xterra Audio jack can be connected directly with the feeder antenna to the back of the stereo.

If Jeff emails me back and explains that this won't work then I am going online to discountcarstereo.com and will order the following parts as this will work for sure: 1. PAC Aai-Nis2 ($75.00), 2. iSimple PDM35 3.5mm Dashboard mount Audio Input Kit ($16.98). This will work and some have reported back ground noise and if this is the case after install then I can get an inline noise reducer for $20 from the same place (PIE 3.5-ILNO In-Line Noise Filter.

Anyway, I will let you know what I find out. My guess is that the Rocksford Fosgate stereo is the same in the 05/06 and 07 so it is just a matter of finding the proper connecting cable. Also notice how the audio jack and antenna cable are only on digit off so I am inclined to think that we are looking at the right cable but is it hard to know for sure.

If your looking for a ipod adapter I have one I got for my 06 Frontier with the RF radio... will charge your ipod and show songs on the radio..
My wife bought it for me and I never got around to the install before a tornado killed my truck. Anyways its new in the box and ill let it go for 60$ plus shipping dang thing cost us 200$ from Nissan
Dave

i got an aftermarket headunit with an aux cable that works for my ipod now i just gotta get one that works for my storm

...ill let it go for 60$ plus shipping...
Dave

That is a great deal. Unfortunately, that is not the route i was going to take. I am going to put some hang-on DVD plavers on the back of the seats for the boys, and i want to be able to play them through the stereo, so the Aux input would be exactly what i need.

Thanks for the offer, though.

John -

Did you get any feedback on this? I have the 2005 RF system with the OEM iPod connector...trouble is, I don't have an iPod...I've already invested in another, large capacity player and simply need an aux jack. I purchased an adapter from cablejive.com that looked like it might solve the problem (pretty sweet, really...female iPod connector to usb and 3.5 audio) but the head unit apparently "switches off" signaling if no iPod is connected (must be some data communication that validates what is on the end).

Anyway, I've searched high and low and cannot find any images/diagrams that show the back of the 2005-06 RF units and the 2007-09 units for comparison. It realy would be nice if an OEM part could be purchased to get this accomplished.

It is funny that you should mention this as I did a little research today on it before and after work. :) Before work I called Jeff at Fort Pierce Nissan and it turns out he isn't there anymore so this explains why I wasn't getting any replies to my emails. So I called my local dealer and they were very good to work with. I didn't have the expanded printout so they couldn't give me any specific info but they seemed very willing to at least try and I really appreciated the effort. They are going to let me talk with their Nissan Mechanic and he is going to check into the back of the head unit to see if he can come up with a solution. We would have done it today but he left for home early. :) I remain optimistic that this just might work but if it doesn't I have all the other parts already added to my shopping cart at the Audio site. I am going to stop in tomorrow and talk with the Nissan mechanic in person to see what we can come up with together. He has been very helpful to me with other repairs so if it can be done he should be able to figure it out.

It would be great to see a picture of that back of an 07, 08 or 09 head unit with the aux port. If we had that we could confirm or disprove that they are similar. My guess is that they are but who really knows as sometimes they make small changes even within a model year. However, I really do think that the back of the head units will be identical and that it is just a matter of finding the right OEM parts. We will eventually get to the bottom of this...just a matter of time and a little effort.

Thank you also for the info on the Ipod interphase to 3.5 jack. I was considering the above iPod connector because it is such a good buy and then going through the process that you described so you saved me a lot of work. However, I really need the aux port for my blackberry.

Well, after visiting my local dealer in person and making a few phone calls as well here is the situation...It appears that the 6CD RF head unit is the same from 05 to 08'. Also, the aux input jack in no problem to find at the dealer and order. However, with everyone that I called the problem seems to be finding the cable that runs from the head unit to the aux input. If one could find this it would be a done deal. However, everyone that I talked to said that the wiring comes with the Xterra new but isn't really available unless you go aftermarket. So with that said I am going to go with the aftermarket option. I ordered my parts this morning and I will keep you posted on the install and how it all turns out once I am all done.

To keep the original aux input jack I even considered getting the PAC Aai-Nis2 and then finding a way to connect it to the factory Aux input jack. If I am not pleased with the final look and feel and the finished product I may still go this way.

Good luck to all you others out there with this same problem. This appears to be a great option though as it has worked for others.

John -

Again...thanks for sharing, this info really helps! I'm going to do a little investigating...maybe the iPod connector I have could be used to 'create' the wiring needed to connect the OEM Aux jack? I just wish I could find a picture of that back of a '07-'09.

If y'all really need a pic of the back of the radio, I'll go pull mine and take a pic for you guys. Just ask. I don't know what the pin out of the radio harness is though, so I don't know how much the picture is going to help.

I did this to my stock radio for a 2002 though....
If anyone needs any help let me know I'll dig up the info I have...
I have an ipod connected but I have 3.5 in mini headphone jack
connected so you can plug anything with this size plug into it!! :wink-big:
the second pic shows the switch i installed to turn on and off
the aux!

i would be interested!

Did you just install an RF modulator in line with the antenna?

no rf mod

I wired into the black 8 pin din plug in the back, you can buy the plug and wire into the pins you need or you could do like i did and solder to the board of the radio
you only use 5 of the eight, 2 for + - left, 2 + - right and one for a 12volt power that actually turns on the aux setting.

I will get some pictures or the wiring later this evening as I have to leave for a little while...

We need to find someone who has done the same to a stereo in a second gen. A picture of your mod may not help the guys who are trying to do this in a 05/06...

if they have the same plug in the back it might work!?!?

Pretty sure it doesn't.

yeah i looked it up it doesen't but what is the other plug for?

jason, are you trying to do this to your stereo?

No, I have an 08 with the auxiliary plug already installed. I just wanted to see if I could help KillerB and JCAndrews try to create one in an 05/06.

I'm off the rest of the week after tomorrow, so I'm gonna pull my stereo and take pics; I'll also try to see where the wire from the aux jack pins into the wiring harness. Probably Thursday or Friday.


EDIT: A quick bit of research at courtesyparts.com shows different partnumbers for the RF stereo head unit in the 05/06 from the 07/08, so it most likely can't be done. But we'll see. Don't give up yet!

P.S. Does the Rockford stereo in the 05/06 have an aux button on the front?

do you have an ipod connected to your aux?
and if so do you use the headphone jack or the line out on the ipod,
I had mine connected to the line out from a special cable I built myself,
and If anyone doesn't already know the line out is a much better connection...

If anyone wants to make an aux out for there stereo, probably the only
way (for free and not rf mod, or PAC)they will able to do it is to (not for the faint hearted)...:chainsaw:
is to open up the head unit and and solder directly to the board!!!
Once inside the head unit you can solder into the cd line in or...
for someone with unused plugs (that are for SAT or extra 10 disk changer, or mabe for some type of phone) I don't know what is available for the R F ?? the board should be marked inside for r+ l+ R- l- line in.... IT CAN BE DONE...:lesen-big: there are tons of info online about this although not this specific head unit...

BUT.... all that being said :boese2-big:
I did it and there are two problems....first is- the volume was not as
loud as the cd player, even using the line out from the ipod, which is much
louder and clearer than the headphone jack, for some people
this would not be a problem....for people who have just the factory
system, no problem....just turn up the volume!!!

But for people who have upgraded there system with subs and amps, like myself, to get the full effect of the system this would mean adjusting you amps and such every time you switch between ipod or cd/radio...

The second problem was the lack of ipod control, you have to select the songs on the ipod you want to listen to... for some they may not mind this, but in the end this was something I didn't like, so I did the mod then decided to upgrade to an aftermarket player with ipod control and the abillity to match input volume
on the head unit, which the stereo i chose was able to do.:lutscher-big:

Yeah, I hear ya on all that. If I had an iPod, I would get the Nissan iPod kit, but not having one and never planning on owning one, I don't have the need. I have a Zune and it is annoying to change songs on the unit itself, but, since the Sync systems in Fords/Mercuries are the only stereos that can control the Zune the way you can control your iPod with your aftermarket head, I just have to put up with it. I don't listen to the Zune that often, because of XM radio. Mostly, my wife and I use the aux input to connect to the laptop so whichever of us isn't driving can watch movies, which sound pretty decent on the truck's stereo.

I thought hard about replacing the entire system (I'm not fond of the sound quality; more specifically the inability to adjust the bass/mids/treble just right) but, I like the factory Bluetooth system with the ability to press a button on the steering wheel and then just say "call whoever mobile." An aftermarket stereo, even with Bluetooth and steering wheel control adapter probably won't give me that ability. What I'll probably end up doing is replacing the amp with an Alpine PDX.5 5-channel amp and all new speakers. I'll probably have some sort of sound processor as well. But that's a big project, and I'm still in the planning/budgeting stages.

P.S. Does the Rockford stereo in the 05/06 have an aux button on the front?

It does not.

Alright, apparently Nissan pre-wired 05 models (06?) with premium sound systems with a satellite radio tuner connector. That means there is a connector hanging about (behind left side of dash where your left knee would be). Looks to be a 20-pin connector with only 11 wires connected. The pinout is below:
Italics = data lines.
NC = no connection

21 GRN - SAT LCH (-)
22 RED - SAT LCH (+)
23 WHT - SAT RCH (-)
24 BLK - SAT RCH (+)
25 ??? - EARTH (SIG) (also provides shielding of of 21-24 above)
26 ??? - DATA EARTH (also provides shielding of 29-30, below)
27 NC
28 ORG - REQ1 (Request???, maybe to turn on?)
29 PNK - TXD (Transmit)
30 BLU - RXD (Recieve)
31 NC
32 RED/BLK - BACKUP (Fuse 17, hot at all times)
33 NC
34 NC
35 NC
36 GRN/BLK - ACC (Fuse 4, hot in ACC or ON)

These then should correspond to the audio unit:

41 GRN - L (-) (from 21)
42 RED - L(+) (from 22)
43 WHT - R(-) (from 23)
44 BLK - R(+) (from 24)
45 ??? - EARTH (SIG) (from 25)
46 ??? - DATA EARTH (from 26)
47 NC
48 ORG - REQ (from 28)
49 PNK - RX (from 29)
50 BLU - TX (from 30)
51 NC
52 NC

I know this is only part of the puzzle but if someone knows something about satellite tuner's... many possiblities.

OK, more info:

Voltage references at audio unit:
42-41, input ~0-1 V sinusoidal, i.e. audio signal
44-43, input ~0-1 V sinusoidal, i.e. audio signal
45, shield ground for audio signals
46, shield ground for data signals
48-GND, input, ~ 5 VDC, satellite tuner request to audio unit
49-GND, input, audio RX, 5 VDC modulated, maybe ASCII or something?
50-GND, output, audio TX, 5 VDC modulated, maybe ASCII or something?

OK, here is what I think this does, i.e. it is a guess and may destroy your stuff.
5 VDC applied to terminal 48 turns on the SAT mode.
Terminals 41-44 are the left and right channel inputs to the audio unit for this SAT tuner.
Terminals 49 and 50 transmit information such as station number, station name, ect probably using RS-232 or some other similiar protocol.

Anyone willing to verify?

No, I have an 08 with the auxiliary plug already installed. I just wanted to see if I could help KillerB and JCAndrews try to create one in an 05/06.

I'm off the rest of the week after tomorrow, so I'm gonna pull my stereo and take pics; I'll also try to see where the wire from the aux jack pins into the wiring harness. Probably Thursday or Friday.

Hello,
I recently purchased a 2008 Xterra and am looking to install an AUX cable so I can play my ipod without dealing with the annoying FM transmitters. Jason you said you have already installed an AUX cable in your 08. Was that something easy to do and if so is there anyway you could give me some basic instructions or tips. I am kind of a noob at this type of thing but can usually manage to figure things out when I get to it. Any help would be great so I don't have to pay someone way to much money to install it for me.

Hey I have an 06 SE and I have been checking on it as well. Searched online and found a devise called PAC it was Like $120 or something. Any way I found out that best buy installs them for $150. That includes parts and labor and takes about 45 min.
