Default Pioneer AVIC X930-BT - 2013 Impreza 2.0i

Put a 930bt into a 13 Impreza (2.0i) today.
Figured I would share some notes / pics from the install for anyone considering a similar project.

x930bt
Purchased this unit instead of a newer model for the following reasons:

1. Color/Finish of the 930bt is close to color of the dashboard. Most newer models have a darker, glossy finish that looks a bit out of place.
While the unit doesn't look exactly like an OEM unit, the lighter color makes it blend in much better.

2. Adjustable illumination color. Crazy how many models don't have this.

3. Price. Being a 3yr old model this unit can be had refurbished for around $300 if you look around. Newer software from a x940bt can also be installed to make it a 2yr old model.

4. Hackability. Easy to install new maps, disable the nag screen, and disable the in-motion control lockouts.

Dash Kit
I purchased both the Metra kit (95-8905B) and the Scosche kit (SU2029B)
Figured I would try them both and see which one looked better.

Ended up going with the Metra kit (95-8905B) as the 930bt sits pretty much flush compared to a more recessed look with the Scosche kit.
Scosche kit is probably a better choice with a head unit that has a deeper face.

Harnesses
Purchased a 20 pin standard harness, Metra AX-SUBUSB USB adapter, as well as a 16 pin aux harness from SVXDC to avoid modifying the factory harnesses.

I attached a 1/8" male headphone connector to SVXDC's 16 pin aux harness so I could plug it directly into the Pioneer harness.
This combined with the USB adaptor gave me the ability to re-use the factory usb/aux connectors in the center console with no additional modifications.

iPod Video does not work in this configuration (factory 1/8" connector only offers a 3 pole connection), however iPod audio control works perfectly when using Pioneer's cable (CD-IU51) that connects both the USB/Aux ports to the iPod.

Steering Wheel Controls
Used a standard Metra ASWC adaptor.
Tested it on multiple sources and the only differences between the factory radio appear to be.

1. No voice control. This button mutes the audio instead.

2. On hook / Off hook buttons don't do anything unless you are in a call. Would have been nice if these buttons brought up the phone interface on the AVIC when pressed, but not really a big deal.

3. FM/AM Tuner Forward/Back buttons.
On the factory unit a single press of this button moves up or down the preset list. A long press tunes to the next station.

This is reversed on the AVIC. It's not ideal, however it's easy to adapt to the change.
All you have to do is press and hold the button until the AVIC unit beeps (like one second) to select the next preset.

Functionality / Sound Quality
Haven't spent too much time with the unit yet, but sound quality is definitely improved over the OEM radio and it offers a bunch of additional functionality (navigation being the biggest addition). Will add more notes after using it more..

Swanky. Did this version of the Metra kit come with the correct "wings" to engage the mounting screws? The one I bought not long ago did not, and I wound up having to combine it with the metal wings off of the OEM head unit. Some hacksaw violence was required.

You forgot another important feature of your unit, which is also the reason I got an "old" JVC NT3HD: It's got an actual volume knob on it, not some stupid touchscreen only or clicky-button volume control arrangement. That's a must have feature for me. Maybe I'm old school. All the new models in the local Boom Barn did not impress me because they had clicky-button plus and minus volume controls that were slow and annoying.

Where did you mount your GPS antenna? I wound up sticking mine to the dash and running the wire through the little punch-out directly to the right of the defroster vent. Presumably some feature goes there if you get a car that has a higher trim level than mine, though I do not know what that could be. Light sensor? Factory GPS antenna? Since my car was originally a stripper model I obviously did not have that option selected, so I may never know.

Did you bother to fish the tach wire out of the harness behind the instrument cluster?

My Canadian STI Sport-Tech came with an X930BT factory (see this thread I wrote). They just stuck the GPS antenna to the top of the X930BT, inside the dash. The dash material is transparent to the GPS signal.

Now, that being said, the 2012+ Impreza might have more metal over top of the head unit (since it's lower down) and that may not be as feasible, but honestly, I'd just stick the antenna on top of the unit and see if it works.

The Metra kit (95-8905B) and the scosche kit (SU2029B) both mounted up perfectly to the car/radio. I believe that the older Scosche kit (made for the last gen impreza / current wrx) requires modifying the brackets like you did.

Definitely. Being able to quickly turn up/down the volume is impossible with a rocker switch.
For some reason the car audio manufacturers go through cycles... no knobs... then knobs.. then no knobs again. I remember when Eclipse brought the knobs back in the late 90s as NOB (No Ordinary Button). They were marketing if it was some sort of incredible innovation.

The factory location for the GPS is right on top of the gauge cluster (underneath the plastic cover).
I however, just stuck it to the top of the radio itself (like evilspoons described -- I probably got the idea to do that from his thread) as I didn't feel like taking the cluster apart. It works perfectly.

There was actually a speed sense signal at the 20 pin harness behind the radio in my car.
Was used in the OEM radio for the speed sensitive volume control.
Not sure hooking it up really provides much benefit though. And in some head units it can cause feature lockouts while moving.

Right: 2012-up Impreza and Crosstrek, and 2014-up Forester have VSS at pin 19 on the 20-pin radio harness.

For models that don't have that (older Impreza and Forester, and WRX/STi through 2014), you can find it much easier in the passenger footwell. See this thread. Location and factory wire color for VSS and reverse gear have been the same for years.

In Impreza/WRX/STi, you should be able to see the harness with VSS without needing to remove any panels. In Foresters, you do.

AVICs use the VSS input, in conjunction with reverse gear, for dead reckoning -- to improve position tracking during times you have poor GPS reception (tunnels, urban canyons, mountain canyons). So it's not mandatory to connect them, but it might help you some day when you need to back out of that dead end street underneath a bridge.

They'll also help when your HU has been off a long time and it's taking longer than usual to acquire the GPS satellites.

Hm. I didn't know there was one on the factory radio harness. Mine has zero features on it, though -- I thought there were different harnesses depending on which factory stereo your car came with? I'll have to check it out. (Mine is not connected at the moment, but I will install my rear camera soon so finding the reverse signal might be nice some day...)

2012-up Crosstrek and Impreza (not WRX/STi) also have the reverse gear and parking brake signals on the 16-pin aux/mic harness, regardless of which of the two non-nav HUs they got from the factory. So for those with the lower-level CM601U1, swapping in the better CM631UD with the 4.3" screen is 100% plug-and-play.

But if you go aftermarket, I can include any of those wires (VSS, reverse gear, parking brake) on my respective harnesses. Most people simply bypass rather than using the car's parking brake signal.

That is a relatively new feature of the ASWC. Metra added the ability to assign two different commands to each button, for short or long presses. That was added in firmware version 3.13, around May 13, 2013.

The ASWC defaults to assigning short presses of the tune up/down buttons to send the same commands they were sending in prior versions. The ASWC defaults to assigning long presses of those buttons to send preset up/down. Note that not all aftermarket HU brands support commands for present up and/or down.

You could manually program the ASWC to reverse those long/short assignments, so that short presses would give you preset up/down. But then while in CD mode you would need to use long presses to make a CD go to next/previous track.

That's how the PAC unit operates in my Sport-Tech STi (the one with the X930BT installed at port)... except once it starts scrolling through the presets, it does so at absolutely insane breakneck speed. It will go through all the presets in like a second.

Does the 930bt have the same parking brake wire issue as the other Pioneer nav units? Mine was almost useless until I did the parking brake bypass...

Yes, but I didn't do the wiring "trick" to get it to work. I did a software mod that tricked the firmware into thinking it was a European model, which adds a "safe mode on/off" menu option. When you turn off safe mode, it lets your passenger enter addresses and stuff while the car is in motion but it still won't show video as the car is driving. Perfect, if you ask me.
