I'm gonna be doing pretty much the same thing soon. I just picked up an 07 STI HU complete with the ash tray aux port setup. I already have the upgraded speaker system with sub in my 04 WRX and was worried about my under seat sub still connecting sine I keep reading posts saying the 07 HU drops the amplififed sub connection but I guess from reading what you've done everything should be OK........

While some of the Subaru radios include a 5th-channel amplified subwoofer output, the OEM sub can work with or without it.

See the two subwoofer posts in the "Stock HU" thread and the link to the thread about modifying the subwoofer T-harness to work with radios that lack the sub output.

That trick also applies when you want to use your factory sub with an aftermarket radio.

First, take a look at the information on the OEM subwoofer that I write in this thread:

Stock head unit information -- pin-outs, subwoofer, aux inputs, and more

Each subwoofer cable is a "T" — it has both male and female connectors and installs between the car's harness and the radio. So you can plug two subwoofers in a chain between the car and the radio. Other people have done this without any problems.

As for the bracket, many people have been able to bend the bracket to work under the opposite seat. Others have simply used heavy Velcro to secure the sub to the carpet.

The bracket may be available by itself as a replacement part. Check with the online sellers such as SubaruGenuineParts.com .

Any difference (front & rear) besides additional tweeters in regular WRX?

I picked up an 07 radio with aux input and the Sirius tuner package and I've run into a few problems trying to install them. First I have no clue where the hell to put the aux input assembly....it doesn't seem like it will fit anywhere in the car without some handy Dremel work. Second, there appears to be no possible way to install the radio with the Sirius receiver attached to it. It appears to be physically impossible to fit it in the dash once it's connected to the bracket and the radio. Anyone else been here and done this?

On the 2007 car's harness, some of the factory colors (column "A") may have changed slightly from that table, but I think most (if not all) are the same as 2002-2005.

does anyone have the pinout for an 07 wrx with the accurate factory colors? I have serched for a while now, with no results

The Aux input goes in an 05+ ashtray.

[ScoobyNubieToo!]

Any ideas on where in the car I can put it otherwise?

[LastResort]

Center console

[ScoobyNubieToo!]

^Where on the center console?^
I don't really see a spot big enough to mount it. Right now, I have the piece hanging under my dash board out of sight with an aux line running to the center console. I' interested to see what others have done. I also still haven't figured out how I'm gonna mount the Sirius tuner. I think I might just resell it and buy a portable tuner anyway.

Since the 07 cd-changer has a CeNet interface (for the Sirius tuner) can that be used to attach other CeNet devices, such as an ipod? Clarion has a couple of adaptors - the CCA-IPOD and the EA1251B - do either of them work with the stereo?

I know that the 2007 Forester still uses the same wire colors as 2003-2005.

Does your car not still have the plug? If you have that, you can identify the wires by looking at the pin numbers on the plug and then looking up the functions on my wiring table — the pin function/assignments have not changed.

If you do that, let us know which, if any, of the wire colors changed.

In another thread, I read that somebody was able to cram the Aux pod in place of their ashtray pod. If I recall correctly, they said it was snug, but they didn't have to actually trim anything. I think it did not lock into place like it would on an '07. Not sure if this was in an Impreza or a Legacy, though.

Try mounting it on the bottom of the radio instead of the top. You may need to modify the bracket, construct your own, or use something different like Velcro.

Worst case, the Sirius module doesn't have to actually be attached to the radio.

Other people have tried using a "generic" Clarion Sirius module with the Subaru radio, but it does not work.

They did determine that the connector, pin-out, and interconnect cable are all the same on Subaru vs. non-Subaru CeNET devices.

Clarion uses rolling-code encryption on the CeNET bus, so it appears that Subaru devices are programmed to talk only to each other.

i thought that it would be like on your photos, but when i opened the box i found that it is black (ACC unit)

The problem is that it shows the temperature, mode etc but it doesn't respond to my actions. I push buttons but nothing happens.

Do i have to change anything to install it, or it should be connected to the original plug in the car without any changes?

I'll make photos an maybe videos today.

LHD Legacy spec. B, single zone based acc unit, my2005 bought in Moscow, Russia.

Did anyone find a solution to this, as I have the same problem?

[LastResort]

There is going to be more Legacy specific information at legacygt.com

Does anyone have info on the rear of an '08 nav unit? It cannot be hooked up to the factory ipod adapter so i assume it's different than the stock headunit.

Here's a pic of the rear of the radio...

It uses the old 14-pin harness as previous model years for speakers, power, illumination, etc. (white connector in upper-left corner, above the fan).

Looks like it also has the new 20-pin connector that some other 2008 Subarus use for speakers and power (white, in upper-right corner). So this radio could be installed in cars that use either harness (wrong). The 2008 non-Navi HU only has the new connector. See this thread for more pics: The 1st comprehensive 2008 impreza dash & radio removal guide ADDED: The other white connector has 24 pins and includes nav-related wires. See the bottom of this post for a better pic.

They've dropped the CeNET connector, which was where the iPod adaptor (as well as a Sirius or XM satellite receiver) connects on previous models.

The square white 8-pin connector at the far right appears to be the same type that has the Aux input, similar to recent earlier models. It may also include pins for remote buttons on the steering wheel. That may be your best bet to connect an iPod. ADDED: The wires for Aux-in, SWC, and CAN data bus are on the white 24-pin connector.

I think that the black connector at the top center is a 20-pin for the Nav and Sat functions. Information is scarce at this point because the car is so new, but I'm still looking. UPDATED: The larger black socket is for an external CD changer.

[bwanaaa]

tnx for your reply. do you know which wire needs to be grounded on the HU to allow the nav to be operable while in motion? In another thread, a gray wire is identified inn the older subarus, but i do not see gray on the list in the thread you referred to.

Hey everyone!!
I just completed my NAV/DVD Lockout overide and it works great and is super clean. I also installed aftermarket subs with this factory Navigation unit and it actually sounds great!

I have all the info here:
http://www.webjogger.com/WRX/2008WRX/08wrxnav.htm

And yes, The larger black connector connects to the stock satellite radio(s)

[casionerd]

Also, the 07 Sirius receiver will not plug and play in the 08. 07 Sirius receivers will only work on 07 radios. It wasn't an option prior to 07 and Subaru changed the connector in 08.

[bobaru]

I just found out, the 2008 Navigation Unit will also play MP3 DVDs!! Just load up a DVD with all your MP3s and off you go. I tested with DVD-R media packed to the top with MP3s, and it works great!! Thats about 4.5GB of music. I have not tested DL DVDs like this, but in theory, that would work as well, as most video DVDs are dual layer, so I think it would read it. That's like 9GB of music... And they want to sell an iPod adaptor for how much??!!??!! HA!

[Mikeyrad]

Any idea why the right channel would be out? I have a 98 Legacy GT wagon. I tried swapping HU's out and no change. Speakers are all connected

[LastResort]

swap the speakers.


And post your own thread.

[brtbendele]

Is it possible to plug in my HD radio tuner i bought instead of the sirius reciever? I just need to hook up the left and right rca outputs to the stock 07 wrx stereo so that I can push the SAT button to listen to HD radio. Is this possible?
