Nissan Clarion 12 pin connector help

[StarkRavingCalm]

Ok. I am trying to hardwire my ipod into the CDChanger plug on the back of my stock radio. It is a 98 Altima with a Clarion PN-2213I radio.

My challenge right now is to get the HU to switch to CHG or AUX mode.I have read here and other some Nissan forums about people getting this to work, but all of the posts are older and the links are now invalid (or they reference the models with an 8 pin DIN connector)

Can anyone either point me in the direction of some valid links or, if they have done this successfully, let me know what they did?

Thanks!!

Here is the pinout:

p2 p4 na na na na p10 012

p1 p3 p5 p6 p7 p8 p9 p11

p1= L -p2= L+p3= R -p4= R+p5= GRDp6= SHLD GRDp7= NAp8= Slavep9= RXD (CD Combi)p10= TXD (CD Combi)p11= AUX Onp12= Combi On

it's been a while since I have played with something like this but I know that pin 11 is the key. Take a meter to it and see what it is showing for voltage. You are going to have to either ground it or put 12v in to it.

Good luck

I am using the harness XIAH-NS1 (for connecting to the Axxess interface).Pin 11 is empty on that. If it is truly needed, I can add a wire to it.

My theory is that even though this was made for a specific interface, it is getting all it needs from that connector (the ability to switch to AUX mode for instance).

Check continuity between that pin and the rest in the harness and see what happens. Usually you just have to push the cd button a few times to get to changer/aux mode.

Edit: I'm still thinking din cables so forget that. If it won't go into aux it is possible that it won't work with you radio.

I've wondered why the AUX ON pin is not connected in this harness. But, in reading the documentation for the Axxess interface, once the interface is connected, you can hit the CHG button on the HU and it will go into AUX mode.I figure everything it needs is in that harness.

I will test as you suggested though.

Found this post and decided to go for it:

No linking to competing sites please (great link though)

Since the AUX ON was not in the harness I decided to solder a lead to the AUX ON pin on the board and while I was in there I decided to solder one for Combi On as well (just in case).

Following the other people in the post, I connected the AUX ON and RXD wire and BAM! AUX!. Plugged in the iPod and got sound.

So.. that works.

I just need to solder the RCA connectors (they're just wire nutted right now) I have along with the line driver I bought.

And lastly, find a way to have AUX (or CHG) come on when I press the CHG button on the head unit, I dont want to use a switch. I know this is possible, just not how.

I'm going to guess that you have to make it "see" a changer on the line. Possibly just a decent sized resistor on the power and ground outputs to complete a circuit? At that point you might also be able to find a switched output that tells the changer to play and wire that into a transistor to switch the input? If I had time and a stock radio laying around I'd try to help figure it out, I'm here to help bounce ideas though.

Thats what I am thinking. There was a good post about a guy with a Kenwood system where he detailed how to do this:

More details on the plug can be found here:

I am going to try this out based on the above to links ( I am assuming the same theories apply).

I might suggest that you try a resistor more in the 1k ohm range, you'll still only be flowing 12mA through it but it might be more likely to sense it.

Scratch that, start with 10k, if it doesn't work try 1k.

[StarkRavingCalm]

Currently I am using a harness made for the XIA-I01.The connector for the XIA-I01 end has a resistor between:CD Combi TXD and 12v Switched.

I have clipped off the connector going to the XIA-I01 (but still have enough lead in the connector to tell what wire went where).

I should probably try connecting the TXD lead to one end of the resistor and the 12v switched lead to the other end of the resistor.

Will stepping thru different resistors (as you suggest) be safer?

Honestly I think if you keep the current under 200mA your chances of burning something up are very low. That being said less is better in this stuff, 1k should be more than safe by a lot.

[StarkRavingCalm]

Ok, here's what I have for testing. I was concerned about crossing one of the pins with 12v power so that why that is not represented here.

This was done on a multi-meter measuting ohms. The first section of numbers is just the two points and the second section is with the CHG button pressed.

Slave\GRD 0 \ 0Rxd\GRD 0 \ 0TXD\GRD 0 \ .7MAUX\GRD 64.7k \ 64.7kCOMBI\GRD 0 \ 012v Constant\GRD 0 \ 012v Switched\GRD 0 \ 0

Does this give any clues?

Does this help?zerothread?id=194403

[StarkRavingCalm]

I had seen that thread previously but it looks like what I have now, a switch to turn AUX on on the HU. I am trying to have it switch to AUX or CD Changer mode by pressing the CHG button. I don't think anyone has been able to do this yet

Ahhh, you want to be able to press the CHG and have it switch into AUX mode ... Not sure if anyone has done that. You might try shooting Shane (qsiguy) an email and see if he has any ideas.

Bump for the exact same problem.

I cannot find the pinout for the xia-i01 box, I finally stumbled on this thread. NICO FTW yet again.

When I started this "project" had the unit powering on to charge my iPod but no sound. The manual for the harness for my 95 uses an illegible foldout style diagram, and they radios are interchangable and their output has to be controllable through that 12 pin connector. The limitations for models is something I find a little strange since the 97j has the same radio as the 99Q although this component is available for the Q.

Through frustration I may have separated the 12 pin connector entirely, they are pretty flimsy. Now I am sort of lost I managed to find the pinout from the 98 Q45 that has the same radio and as the OP said a while back, I wanted to use the unused CD CHG button to activate the AUX function that this radio has.

The wires on the female end of the harness look pretty straight forward pinout wise. The colors almost fully match a normal wire color code, there are a few extra ones that I cannot find though.

I've been staring at this for a few hours and tried several variations based on pinouts from the esms. I did not try crossing the tx line and the power.

If this makes no sense I apologize this simple addon to my radio has consumed the better part of my day and now I need another beer.

This is why I stay away from the aftermarket.

Oh and does anyone know where I can get a microphone for a Parrot Mx6000 BT unit? Some D bag cut the wires the unit that I have and I cannot fix the coaxial cable enough to get a strong enough signal.

/rant ugh it's been a long day.
