The 94 Q45 Bose/Clarion HU PN-9556Q has 2 DIN inputs. The one closest to the middle (6-pin DIN) is/was for the phone.

Is the other one (8-pin DIN) an AUX input (or better yet a line out)? If so, does anyone have the pinout?

(I posted a pic in the Car Audio forum).

There are some "off the shelf" items for sale, but they're close to $100.

I bet these plans could be updated to directly connect an ipod docking plug (instead of RCA R/L only) and control the ipod from the HU. I would definitely yank the CD for this.

I know I've seen a pic somewhere of the HU showing "AUX" in the display (maybe I dreamed it).

Now curiosity has the better of me…I really want to know is what the 8-pin DIN is for.

Is it an AUX input...if so, what was it for? I'm not aware of any additional add-ons that would use the audio except the phone.

Is it a line out? This would be too cool...that would solve my other concern about pulling a signal for a line-out converter directly from the speakers.

Thats what the 2nd thing is for.

Yes, there was a (now defunct) web site from a Maxima owner showing as such and offering an adapter, but no diagrams.

Here's a couple more diagrams I have.

That DIN connector isn't for an antenna. Both antenna leads go to the same plug as show in one of the later pics.

Anyone tried this on the Q radio or is it the same as the Maxima it was designed for. Funny, just a few days ago I was testing the cd wiring back by the changer with my ocsilloscope to start working on a aux input system. If this works it'll save me a lot of work.

I will most likely be building one of these, or all, to test. I think I would integrate a switching circuit so you could still use the CD if you wanted.

This is great info.

Should be the same as the Max Bose, though 98 and up may behave differently. FWIW, I am controlling a 95 Q45 CD with my 99 Pathfinder HU.

Let me know, as I would hope my pics/diagrams/schematics coudl score me a discount .

There is a couple devices available, but to have AuxIn and autoswitching would be close to $200 ... might as well go full aftermarket at that point . Not that $200 will get you much, but I've got a single DIN Kenwood CD, single DIN Kenwood 4 MD changer and a nice old school Phoenix Gold MPS amp ... so I'm part way there.

I'd still like to make my own circuit because that would be kewl! What do you want a discount on? Of course I'll hook you up! Do you need other products or were you referring to one of these aux input adapters?

So is the '95 Q CD the same as the '94 Q?

I've been doing some checking and I am not seeing anything available for these models from my distributors. Anyone have a part number for an input adapter that they know works for this application? The only one I can find that seems to be for this application is the PAC AAI-NIS but all the retailers I have looked at say it's discontinued. I'll call my vendors tomm. to see if I can still get it anywhere wholesale and if I can get a good deal on them if they do still have it. If the price is right, does anyone else want one of these? If they are not still available I'll have to make a few according to Rex's diagram, assuming I can make it work.

1995 Q45 89,000k Cabernet Pearl SOLD

2007 Audi A3 3.2 Quattro S-line 6 speed DSG

At this time, I have a 1999 Pathfinder Bose in dash CD player in my 1995 Q45 using a Nissan adapter (PN#24028-3B300, 300ZX sub harness). It also controls the (factory pre-wired) 1995 Sony 10 disc changer with no issues or quirks.

So, are there items listed as compatible or available for the 1999 (and newer) that give you AuxIn options, as I am also bored/tired of using the cassette adapter.

As for a "discount" I was referring to if you made some adapters to sell to NICO members (and I think you could sell them if you choose to make them). If you find an "off the shelf" item, I'll pay retail ... or close to it.

Is this the same PAC part? http://www.crutchfield.com/S-Z...11NIS

I would be much more inclined to update my Sony MD to an iPod-ish device if this functionality was "solved".

Great discussion BTW.

I'd be all over either option in a heartbeat if you can find the PAC piece, or make your own. Either way, keep me in mind if you would!

I've seen that US Spec thing before. Thay have it as not being compatible with the Q HU.
They say it works with newer Infiniti and Nisan HUs.

Wow. You must be one of the few that use Mini Disc. I thought only musicians used those in the studio to make quick copies of their music.

I have a 1999 Pathfinder HU on my Q, so I'm curious to know if it would work???

The discussion comes up from time to time, and it seems myself, Jesda and Chris (HashiriyaS14) all have/had them. For me it's great, I plug it into my Digital Cable box (via a fiber optic cable) and let it record over night. The only downside to that is it creates 1 single track, that I have to but "breaks" into. But the edit features of an MD is great. Not only can you add/remove breaks, but you can move tracks around on the portable MD player.

I should get over my fanboi iPod desires.

Says you can use it with any Infiniti HU between 99 & 01. Maybe if one
could swap an HU from a 99-01 Q. That might be the ticket, but I'd rather
not have to.

Sounds like he is "the man". He's already done what we're trying to do here...per his post in the G50 owners thread:

I have an XM tuner connected via the stock headunit's AUX 2 input.
More pics & details at: http://www.cardomain.com/ride/2299831

Check out his install...especially the placement of his XM...sweet!

I've sent him an email...I hope he can help clear this up.

The Peripheral model PXNI says it's for '04-05 350Z/Maxima/Quest, '03-05 Murano/Pathfinder, and '05 Altima. I think we're out of luck with this one too. Peripheral also has one called the "Aux2Car" but the only Nissan on the application guide is the '99-'02 Quest using harness #PXHFD3. Anyone know if the Quest radio matches the Q or the '99 Pathfinder radio Rex is using?

I think I may start aquiring the parts for the plans Rex supplied and see I can make it work.

Don't you guys have a box full of OEM take outs in a box back in the intall bays?

hehe, yes actually. I'll have to look again but I don't remember any decent Nissan/Infiniti Bose radios. Anyone remember the movie Office Space when they take that printer out to a field and smash it up? That's what we usually want to do with Bose radios hehe

OK...if I use Rex's pinout above:

1: AUX ON SIGNAL INPUT
2: COMBI. ON SIGNAL OUTPUT

In theory, if I run a jumper between 1 and 2 the head unit will switch to AUX and play the signal coming in from the AUX audio inputs.

Is this correct??

I wish I had a head unit to play around on...found one on ebay for about $20 bucks last week but someone nabbed it. If anyone has a head unit (working or not) that has the 8-pin DIN input in the back (see pic above) and would part with it cheap, let me know.

The other issue is that even if you get the Aux to turn on I'm not sure if the audio inputs are standard low level RCA type. The circuit Rex supplied indicates you need to construct a single ended differential converter. Bose typically uses proprietary inputs/outputs for their equipment. That's why you have to use converters for everything.

A couple weekends ago I did cut the CD Changers audio output leads and turned it on to activate the cd input. I tried to feed an audio signal from my MP3 player into those audio input leads and it didn't work. This possibly confirms the need for this converter on the audio inputs.

I'm heading to Vegas until next Monday, hopefully I'll get a response by then.

I don't think so. There's a compatiblility chart and Instalation instructions and it says Q45 98-02. Here's the link.

http://www.discountcarstereo.com/pdf/auxniss.pdf

INFINITI

1998-02 G20- All

2003-04 G35

1998-01 I30- All

1998-02 Q45-- ALL

1998-02 QX4- ALL

Warning: The AUXNISSv3 is only compatible with the Model/Years listed above and will not work in others even
if the radio has a 12-pin connector (i.e. 1997 Maxima). Please do not purchase this part if the vehicle in your car
does not meet the requirements (12-pin cd changer connector, CD/CGH button)

I guess the question is which one of these radios fit in the G50. I'd rather
not have to do that. Hopefully someone figures out how to do it with the
G50 HU.


Modified by louiegz at 11:19 AM 9/1/2006

louiegz, we already established that some other radios are compatible with our G50's. Rex has a 99 Pathfinder radio plugged into his '95 G50 cd changer. I think we can make the soundgate one work. Anyway, if my wholesale price is good I'll buy one to test. If it doesn't work I can always sell it to someone that can use it.

Here are pics of the install.

I have since ditched the whole bose system and went with HD Radio.

This unit will directly control an iPod, but I have no interest in an iPod.
It is also a DUAL SERVICE sat radio tuner! I have XM AND Sirius.

NO.. Momentary contact pin 1 to GROUND to turn on the aux.
As for the connector, I MADE it. it;s just an 8 pin DIN with a set of RCA jacks & a wire for the turn on soldered in it.

I'll report back with my notes.

I'd be interested to see what you end up with. I meant to hit up Radio Shack yesterday for some parts, but didn't find the time.

To connect into the RCA's I used a 3.5mm stereo plug to male RCA adapter. This plugs into the headphone jack on the MP3 player and then plugs into the Aux input adapter RCA's. You could really feed any audio input you wanted. I think I might build a switch so I can have multiple inputs through Aux 2. My MP3 player, XM, DVD player, and maybe a cell phone hands free.

First photo is the back of my radio. There are two aux inputs but the one that is being used here is for the cell phone (not used anymore) but it's only a 6 pin DIN. I tried briefly to see if there was an input ON wire to activate it but it didn't. It might just silence the radio audio when a signal comes through.

This is the only diagram you need. Terminals 2, 3, and 8 are not needed

Here are some photos of the adapter I made.

Here is the adapter plugged into the radio with the 3.5mm adapter plugged in as well.

This is where I came up through the console. The cell phone cradle used to be here and it left a hole after I removed it.

Here is what the radio display says after you trigger the input with a ground pulse. Also, my MP3 Player a SanDisk model.
