Default Upgrade to in-dash changer without new harness?

I have a 2005 outback in need of a new stereo head unit. It has a single disc CD now. Anyone know if I can install an OEM 6-disc changer without rewiring ( using existing harness)?

Yes, you can swap in any 2005-2009 Legacy/Outback HU, as long as it has the exact same type of A/C controls as your original HU (manual or automatic, single- or dual-zone).

All of your car's harnesses will be plug-and-play. However, if you get a 2007-up and want to use the aux input, you'll need to make some mods. See this thread for starters (including my posts in the last few pages of that thread).

Hi~
Will the OEM 6 disc head unit from an '07 Impreza fit into an '04 STi without modification?
Thanks!

Yes. Body is the same size, and the 14-pin power/speaker harness will be plug-and-play. If you got the ashtray aux pod with the 2007 HU, I think people have managed to install that in place of an older model's ashtray (but it might take some trimming).

Thanks for the reply!
Does any of the'06 & earlier head units have an aux in port?

No, 2007 was the first year for aux in Imprezas and Foresters.

One last question; I have an OEM subwoofer from my '05 Impreza - will that plug into the '07 head unit?
Thanks again, SVXdc!

SVXdc,

Is it possible to install a 2010 WRX headunit into a 97 Legacy? Does it require any cutting of trim? How is the aux/usb wired in the 2010 head unit?

EDIT: Read post 11 in the FAQ's. Is there a kit which brings the face "out" to make it fit in an older subaru?

I did not find a 14pin car to 20 pin HU harness listed in your website. Any compatibility issues?

You sir are a wealth of knowledge on these things. Thanks for the help.

No dash kit available that I know of. You'll have to take a saw and open up your Legacy's dash opening 1" wider total (1/2" on left and right sides).

2011 was the first year for built-in USB and Bluetooth.

Aux is the 8-pin connector, described earlier in my 'Subaru stock HU' thread (same as on 2007 Impreza HU).

I've built 14-to-20 pin adapters for several people who did this type of mod. If you're serious about hacking your dash, e-mail me for details. I can also make an adapter to connect something into the HU's aux port.

In my '05 Outback Sport I just swapped out my stock P133 6-disc changer for the P130 6-disc changer with weatherband from an '04 Forester. The stereo works fine, but the underseat sub is working inconsistently.

Any ideas on the issue? I re-checked the wiring already.

Instead these buttons move the radio station up and down and the bluetooth button has no function. I bought the unit and the axxess interface used from another 2011 wrx owner. I wanted to know if your harness can get me the functions back or if it's a matter of my axxess interface being not updated? Any help would be much appreciated. Thanks.
Since the ASWC is seeing all but one of the buttons, that means it's wired correctly (though unless the installer had my harness, he likely hacked into your factory SWC wires to do it).

So the problem is purely the ASWC's programming, and switching to my harness won't solve it.

Since most Pioneer HU models don't support any of those functions, Metra opted to default to assigning those buttons to do audio functions -- seek up/down and mute/ATT. The ASWC can't detect which particular HU model you have, only the brand.

Go through the ASWC's "Remapping Buttons" procedure and you should be able to get the on/off-hook functions working.

For the AVH-3300BT, you'll need to choose some other audio function to assign to your WRX's PTT/Voice button. It sounds like that model may not like the "mute" command, but I'd try it just to see what happens.

If the ASWC is really old, then you might need to update it with newer firmware. What are the manufacturer's build code and date printed on its label?

Did you check out the links in post #1 of this thread?
Stock head unit information -- pin-outs, subwoofer, aux inputs, and more
The pictures in the 'changing the Radio to red' thread are dead, but his written description may still help. And the other threads for 2002-2004 models still work (along with the links to additional resources in my post).

I just got a 2009 Impreza WRX. It has a head unit with GPS navigation. My problem is that the auxiliary input is way too quiet even with the volume up to 40. I am using the red and white RCA jacks in the center console. The source is an iPhone 4S (also tried an iPod Nano - same problem). The volume on the iPhone is set to maximum, and it worked fine with the aux input of my previous car. The FM radio volume is loud enough at 20 and way too loud at 40, so I'm pretty sure the problem is something with the aux input, not the head unit or speakers. Anyone ideas as to what might be wrong?

SVXdc - more questions about the stock McIntosh premium system in a 2003 Outback VDC Wagon... i've been using this site as the guide for making the cable to connect an aftermarket Clarion CX-501 into the McIntosh amp and speakers:

http://nzlamb.wordpress.com/2010/06/...i-information/

the problem i keep having is that it keeps having "alternator whine". the problem i gather is converting the Unbalanced RCA's into the Balanced input the amp requires.

i've tried the RCA (+) to the (+) inputs of the McIntosh DIN cable, and the RCA shields to the (-) inputs of the DIN cable. this configuration seemed to be the quietest, but it was still not usable. since then, i've tried connecting both the DIN and RCA shields, with the DIN (-)'s disconnected, and that was very noisy. i've also tried connecting both shields directly to the headunit ground, and it was also extremely noisy. and i've tried both the RCA shields to headunit ground, and it was also extremely noisy.

in the above website, in the comments section, people have asked this same question, and the answer talks about connecting to the #6 and #12 pins as a ground, but i don't understand how to do that when those pins connect to the DIN shield. obviously, i'm very confused and frustrated. you've mentioned that you have made these cables in the past - how did you wire it to eliminate the noise? any help would be appreciated. thanks!

Shield wires should be connected to ground typically, helps eliminate induced noise on low voltage wires. I would hook 6/12 to the ground that the radio is hooked to.

Also on another note, SVXdc, why is this

Thanks! so if i run the DIN shield to the head unit ground, then what should i do with the RCA shields? just leave them disconnected? and i'm assuming the DIN (-) inputs should also just be left disconnected?

Thanks a lot for your help! I'll try this tomorrow when there's light.

You may wind up needing ground loop isolators. I haven't seen schematics of the Mc amp, so I don't know how they do it.

@CSVT- Why no sticky? I don't know -- you'd have to ask the admins.

Tried a different cable?

Is it possible the previous owner hacked the factory aux harness, perhaps leaving something else tied into it?

The only other suggesting I can think of at the moment is to find another 2008-2011 Impreza or 2009-2011 Forester with the Navi and see if it sounds the same.

Sorry redwagon didn't see you had tried some of that already... Here's what I would do if after utilizing the DIN grounds I still had noise.

If you follow aftermarket wire color standards

White
FL (+) -> Pin 1
FL (-) -> Pin 2

Gray
FR (+) -> Pin 3
FR (-) -> Pin 4

Green
RL (+) -> Pin 7
RL (-) -> Pin 8

Purple
RR (+) -> Pin 11
RR (-) -> Pin 13

Remote turn on (+) -> Pin 5

HU Ground (-) -> Pin 6 & 12

If that has noise I would go purchase a ISVE61, typically found at bestbuy and put it between the radio and the RCA connections. This should eliminate noise/pops and allow you to dial in the proper input level for the OEM amp when using an aftermarket radio. ISVE61 will require you to use the radios High level output (the wires coming off the plug, not the RCAs) for input into it, and then you'll use rca output from the ISVE61 to your DIN cable audio connections.


Or my better question to you, why not just bypass the OEM amp and run it all off the new radio? (at least I'm assuming you're using a new radio) Upgrade to a small amp to run your OEM sub.



Did you see this post, seemed promising... ??

Not sure if I missed it, but after quite some searching, I still can't find it.

I've got a 2012 Impreza Sport with the premium OEM radio now, and I am going to be installing the Pioneer Appradio 2 very soon. I've got the wiring figured out, including the extra SWC wires, but I will be getting a rear-view camera as well.

My question is: where is a good place to tap into the reverse wire so the HU will know to switch video to the camera when I am backing up?

I know that vehicles with NAV have that in the 24-pin connector, but I've got the 20-pin non-nav connector. I'd like to be able to tap into it without splicing a wire, but if need be, I don't mind running a wire to the reverse lights, I would just rather have the wire hooked up somewhere in the dash.

Most people that I saw do the Non-Nav to Nav swap didn't use a back up camera, or there was good info on adding a camera to an OEM nav system, but not anything about this one specific wire...

Thanks in advance for the help.

Easiest place I would say is going to be the taillights where the reverse lamp is at, you'll already be back there to do the camera, so it shouldn't be that much more to tap 1 more wire while you're back there. I'm sure there is probably another spot up front, but without grabbing a multimeter or having a directtechs print off, it's going to be harder to find.

That's the back up plan (no pun intended) and I guess I'll just run that wire with the video wire...
