Hey guys first post! Glad to be part of another message board.

Anyway i got tired of searching the net for my own answers so i though maybe you guys could help.

I have a 2005 Lancer ES and i don't have any problem with the factory sound system or head unit. So, that being said in the spirit of saving money is there anything out there that i can buy or something to hook up to my factory radio to give me a line-in? I would like to hook up my psp to it. possibly a din converter? anyway hopefully i get the answers im looking for. Thanks in advance!

:banana: :banana:

well I live in san jose, ca There this place call digital city in santa clara,ca and they do get work, and ask for rob he work tuesday-saturday. i hope this helps.

lol i appreciate your post man :) but are trying to tell me that this IS possible? thats what i was just trying to figure out. im out here in Cleveland, Ohio so maybe i will google that and get the phone number if no one els responds

if you go to yahoo local you can find a shop.

it would probly be cheaper and just plain easier if you switch out the factory head unit with a aftermarket head unit. you could find a cheaper one or you can buy one used that is still really cheap. i have a panasonic head unit im selling cuz i got a new monitor head unit. and it has a line in and aux in. im selling it for $100 if your interested. but switching them out might just be easier and less time consuming.

Hey man, I'm glad to see someone else is also curious to hack the stereo head unit for aux-in :)
What you are asking definitely IS possible because Lancer's stock units have a CD changer input. Some brands manufacture an optional adapter that plugs into CD changer port (DIN-to RCA output), notably Kenwood. Theoretically, if you know the pins on the changer input, you could trick the HU into thinking the cd changer is available. I especially liked the idea of keeping the stock hu because they wouldn't draw that much attention from stereo thieves, etc.

However, the challenge is not to find the right pins, but to learn how the HU opens the changer audio channels. On Kenwood, some guys simply detected the mentioned adapter sends small resistance, so they plugged a resistor into back of the HU to trick the HU.

Unfortunately, Mitsubishi doesn't seem to provide this adapter for their units, so the HU probably looks for a clock signal from the actual CD changer (perhaps 125 khz clock signal). This is the method used on many older (1999 and earlier) car head units. And I have no idea how you can discover this without the changer itself.

Not long ago, I posted the similar thread here asking if anyone has the changer pinout for the Lancer. One guy responded with pinout. Though it doesn't explicitly say it's for lancer, hopefully all new mitsubishi's HU's use the same wiring. I haven't had any time recently to play with this schematic, but nonetheless, the idea you can get aux-in for $10 or less is thrilling.
Here's the pinout link a fellow posted recently: http://carstereohelp.net/wireharness_Mitsubishi3.htm

Not sure if you are still interested in doing this... i have a 2000 mitsubishi montero sport. I too have the 13PIN DIN adapter for CD changer input on the back of the factory HU. When i pulled my hu out to investigate the possibility of direct wiring an ipod i noticed this cable was plugged into the back of my stereo... just hanging (dangling if you will) curiously and invitingly as if it were saying i was put here for a purpose. The pinout for the end that would go into an OEM cd changer is weird looking, almost in the shape of an S or P or R. I do not know how much more would be involved with putting the right signal into the HU while also providing linke to some type of AUX interface, BUT it would seem that I have a piece of the puzzle that could help in determining the pinout needed to get the wires in the right place for whatever cable needs to be made (parts available at Radio Shack).

I can draw up a diagram if you are interested and if you think you can find a way to get that signal to the HU.

The pinout on the end of the cable that goes into the HU is 3 rows of 4 with a single pin at the bottom in the middle similar to the ones used by Kenwood.

Sometimes car manufacturers pre-run and hide DIN cables because it is cheaper for them to install CD changer and other options while a car is already at the dealership. I haven't looked to see if there's one in my Lancer, but a DIN cable isn't necessary to talk to the L & R audio channels on the HU's changer port. Usually one or two pins send the signal source to open changer audio channels.

Is your pinout same as in the picture on this picture?

Mine has the same physical order, but for example I don't have a fuse as in that image. It's still a Mitsubishi head unit, so hopefully the changer technology is the same.
I did play a little bit with my multimeter by measuring resistance levels between pins. I only detected a little resistance between pins 4 and 6, and pins in the following layout:

1___2___3___4

5___6___7___8

9__10__11__12

_____13______

Sorry for the drawing, needless to say the resistance between 4 and 6 was 560 ohms.

All I've got so far :) Shortening those pins with a resistor probably wouldn't do much good though without knowing the ground pins. I'm not an electrical guru, any ideas would be great :) Even if anyone happens to find another PIN schematic for any 2000+ Mitsubishi, that may help.

Btw guys, don't get the 'changer to RCA' adapter mixed up with a basic 13-pin DIN cable. The AUX adapter made by kenwood looks something like this. It only works for their head units, of course.

If we knew Mitsubishi makes one for their units, no question one could get a simple AUX input. Unfortunately, it tends to be more like the hu's looks for the time signal generated by the cd changer, which doesn't sound promising. You might as well be better off getting a used Kenwood on Ebay that you know supports the DIN-to-RCA adapters.

Well, I tell you what. I live in the Eastern time zone so i am posting this at 9:30 AM and I am at work. When I get home tonight I will post some photos of the cable which I already have disected and also try to make a diagram showing the pins and wire colors. Going off of the diagrams we already have showing us the pinout at the Head Unit should be able decypher which ones the Disc Chnager uses and perhaps be able to figure out which wires / pins we need to use to activate the disc changer function on the radios.

Mine actually doesn't have a button to select the AUX mode so I may be in a deeper well than some of these newer radios. However, I think it may auto-activate the channel when I press the CD button on my radio and something is sending the right signal to the HU.

This is fun.

If you're talking about the factory hu, the CD button controls both the CD and the changer. Except, the changer will only show in the hu display if it's hooked up (or channel activated). On Kenwood, it's a 'source' button, same functionality.

wow cool guys i really thought this thread was dead! well i will tell you one thing im good at following directions but figureing out electrical stuff on my own is a bit over my head :) (<-- at art school). Im eager to see what you guys come up with though! I've searched the entire net looking for something and came up empty handed.
:liebe011:

My observation:

My guess is the resistance between ACC and GND is irrelavant.
I am drawn to the BRXEN pin. I don't know what to put on the B, but the rest, RXEN sounds like Receive Enable. Perhaps active high?

11, 12, and 13 appear (to me anyway) as data request for song title, etc. Ie; request, data, etc...

It does appear there may be some clock signal stuff? I found this, but I don't know if it applies in any way: http://www.softservice.com.pl/corolla/avc/simpleaux.php

I have access to a TTL function generator if anyone can tell us if/what signal we need.

Again, I'm throwing more links for Kenwood, but it's the only reference I've got at this point: http://www.mictronics.de/?page=cdc_proto#Kenwood

I've seen some custom made circuits on the internet that emulate cd changer protocols, but you really need some good equipment handy to do that on the Mitsubishi hu. Some Panasonic hu's I've seen receive a 125 khz clock signal to enable the changer channels. But it's just a wild guess.

Also, I do have a Kenwood with me that I haven't installed on my Lancer yet. But for this unit, simply if you short VCC and the AUX enable pins, it works. Just those two pins.

So I wonder if using BRXEN and VCC pins could be used to produce the same result. Ground probably isn't necessary on the Lancer because the hu is grounded using the metal attachments that hold the deck.

If the hu is in fact based on the clock signal, I'm afraid there isn't much we can do.

hey guys. awesome thread. i think i might have some info to add. I have a 2003 Mitsubishi Galant with an Infinity P003 head unit. Maybe I'm not the first one to think of this.....

i spent a few days figuring out how to splice off the L + R wires from the factory cd changer DIN, crimping them, and using them to "fool" the HU into thinking the audio coming from AUX in was in fact a CD changer. i was ready to do this, and then i took a look at this forum. seems pretty impossible to emulate the necessary handshake to fool the HU into thinking a cd changer is attached. damn.

i called up the nice guys at installer.com and told Dwayne my problem. first of all, this dude is awesome. so patient and wise. Dwayne told me it would be impossible to fool the HU, but I could use a Peripheral CD Changer interface (with Aux IN included) instead of all my crazy engineering plans. After looking into it, this definitely looks possible. You can find this part here. If you ground the grey wire (apparently the manual that comes along with the interface tells you how to do this), you don't even need to have a CD changer hooked up at all. It basically acts as a converter for AUX IN > DIN.

I bought mine through a guy on eBay who is selling them for about $19 + shipping. See here. Not sure if this is the same one as the one sold at installer.com and other places (one is purple and one is green). Gonna try it out this weekend and I'll definitely let you guys know.

Keep in mind that even if you plan to go this route, you still need the factory DIN cable. I read on some forum somewhere that some vehicles that do not have the CD changer still shipped with this CD changer DIN intact, to make it easier for a future install that might take place. I popped open my head unit and it did NOT have this wire there. My dealership is charging me $36.50 or something. ****.

Ok cheers!

Did you look in the rear of the vehicle for the DIN cable? I know for fact other manufacturers like Nissan hide it there. BTW, I'm a little confused over that peripheral. It's a Mitsubishi-to-Pioneer, so it's probably only meant to hook up to the Pioneer HU. It also mentions 8 and 12-pins, 2000+ mitsubishi's all have 13 pins.
Also, if you have the cd changer, it's easy to splice the wires out of a DIN cable because the changer keeps audio channels active. You just intercept the wires with a custom switch to change direction between changer and other source, like ipod.

Good luck though, let us if you learn something more.

Hello Nik,

Nice to meet you. I had read some things about the DIN cable being in the back, but I couldn't find it there. FYI the factory cd changer for the model I own is a head unit insert, not a mountable CD changer, so the DIN cable is not long anyway. From what I understand, the end of the DIN cable hooks into this peripheral device and the peripheral gives the handshake to the HU to make it think that the CD changer is connected, thereby enabling CD changer mode (which is otherwise disabled when you press the (1) or CD keys (all in theory). I bought the DIN cable already and am waiting for the perhipheral part.

So I'm not sure that your suggestion to splice the L + R audio wires out of the DIN cable and connect them directly to the ipod would work because the HU would not activate that mode, especially since i don't actually own a factory cd changer. Maybe I misunderstood and you are assuming I have a cd changer. I don't...

You are right about the pin numbers, but from what I understand, this is meant to hook up a Mitsubishi HU (1996-2004, except for 2000-2001 Eclipse) to a Pioneer CD changer. The only reason I'm getting it, though, is because it also offers those AUX IN plugs.

Should be getting it Monday. Stay tuned.

i was looking on the canadian mistubishi web site (http://www.mitsubishicars.ca/) in the accessories section for the lancer and came across what they call an "ipod adapter" and "ipod harness" (285 for the adapter and 57 for the harness, CAD). so i called the parts counter at the local dealer and after a few minutes of searching he found it and said the adapter essentially added an aux in for the cd changer port on the head unit and the harness added an aux in for lancers equipped with the in dash cd changer. i don't have the changer so 285 is a bit much considering an 30 gig ipod is 350 and i'm not exactly an audiophile. just wondering if anyone else knew of this or has one installed. and if so perhaps there is a cheaper alternative. thanks.

I tried doing the same thing that Ronsta was talking about for my 2003 Montero. No luck and wasted money. I am now the proud owner of one Peripheral MITPIL interface and one DIN cable that plugs into the back of my Infinity HU and hangs there without purpose. The ends just dont match up. Anyone else figure this out. I wanted to have RCA inputs for use with an XM satelite unit and/or IPOD.

Did anyone succeed in creating the aux cable? What was the result of shorting BRXEN and VCC?
