Default Can a 2018 WRX Multifunction Display be swapped into a 2015-2017 WRX?

I want to swap in a 2018 multifunction display into my 2016 wrx. Possible? What are the main differences? Would the swap be just plug and play?

Just speculating, but I'd say no. Probably the programming in the ECU is directly tied to that model year specific display.

yea doubt it will be plug and play. Unless they integrated the UI into the display itself but highly doubtful.

Now the 2018 gauges would be a nice swap. Makes the interior look more modern and a bit more expensive.

^^^ Agreed on the gauges. Unfortunately they cheapened the look of the exterior with the different shades of excessive plastic on the front bumper.

looks like Coop_Nation tried it but the 2018 MFD has a different connector.

Maybe in time somebody like SVXDC will make a conversion harness.

Anyone out there know if the WRX and STI share the same display part number and connections? I was hoping to do this too, but I guess it's not looking possible...

Anyone know how to get a schematic for the 2018 MFD?
It looks like the old MFD schematic is available here:

I wonder if you can move the pins over to the new plug. Hopefully this becomes a possible upgrade. I like that screen better.

Isn't it supposed to simply read OBDII data? If it's the case, while the plugs might be different along with the display itself, the raw data coming it should remain the same...

I bet here is more data coming in via canbus and I wouldn't be surprised if the new MFD is getting its data differently now. That's my guess though. I hope more people tinker with this... I would like to know for sure.

I'd assume the controller sending the graphic data to the screen is different, and even if you could get the data into the new screen, it would display the same screen data as it does currently. It would probably take updating whatever control module provides the graphic data to the display to the current module, which may or may not be possible.

Not necessarily. The old MFD takes data from the can communication system:



Anyone know is the Part no for the new MFD is 85263VA020

Default part number for new MFD

Hi All, wanted to chip in with the prat number and link per request:

Part Number: 85263VA020

link: http://parts.subaru.com/p/Subaru_201...5263VA020.html

hopefully that helps, looking forward to a solution!

Well then it's probably dependent on the type of CAN communications objects in the firmware, and whether the control unit that provides the data is sending the same data. It wouldn't be hard to re-pin and connect the power and CAN connections and see what it does. (If someone has the schematic for the new MFD)

Thanks for the part number! $583 MSRP ($490 from dealer) is super expensive even if there was a harness for it. I usually just leave it on the boost gauge and use my access port for other system information. Definitely looks better than 15-17MY but not worth that high price.

85263VA020 is currently only $469.28 (plus shipping) at SubaruOnlineParts (link).

The main connector on the back is a 24-pin -- same type as used for OEM head units in other earlier Subaru models. So I have the correct plug to fit that. It also has the same 4-pin socket used for USB on the new STARLINK-style OEM HUs, but I don't know if the MFD uses it for USB.

I'd need to see Subaru's wiring diagrams for this newer style MFD to determine if retrofitting it is even remotely possible.

parts.subaru.com shows it is used in several 2017-2018 WRX and STi models, but I'm only seeing the older-style MFD in the 2017 wiring diagrams, and I don't yet have 2018 diagrams. Anyone else have those?

Does the new MFD have active steering path lines, like 2017 Impreza?

I wonder if it has hooks for the side-view blind spot monitor feature?

If you think the MFD is expensive, I'll bet the mirror with camera is even more pricey.

That is so cool!, thanks for finding this. that must be what the extra plug was for in the above video that isnt used in our car! problem is I wonder if they make the camera for the other side mirror. it wouldnt be so helpful for the drivers side (you can just open the door, or peek out the window, but it would be super helpful for the passenger side. more things to research!

As for the Wiring Diagram, Im looking. just a thought would it matter if it was STI specific? would the one for the impreza or forester work , since they should all be wired the same?

The unused 8-pin socket on the 2017 MFD in the YT video (by Coop_Nation) is for the normal rear view camera input, same as on the other older-style MFDs in previous models. Subaru just moved the camera to the larger screen on the STARLINK-style HUs in 2016-up.

There are some models outside the USA that got the same older-style MFD but don't have a rear camera at all (not even on the HU).

On any of those, if you ground the MFD's 'camera enable' line and connect a video signal, the rear camera function will start working. Unfortunately, there's no easy way to trick the MFD into displaying that video input at other arbitrary times; it will only work when you shift into reverse, or go into the dealer setup menu.

Yeah, I wouldn't be surprised if Subaru only made the side camera for RHD cars. I imagine a crafty person could hack a small aftermarket camera into a plain passenger side mirror here, but unless the MFD is smart enough to mirror the side view's parking guidelines, those lines would be completely useless on a LHD car.

If the latest Impreza and Forester models get an equivalent MFD, the wiring will likely be the same. But I'd feel better seeing the WRX/STi diagrams.

Curious to know if this will work (it looks like it might...) Here's the wiring diagrams for the 2017 model year and the 2018 model year. Hope this helps get an answer!

Is the upper display from the 2015 to 2017 models one screen or two screens?

If the upper display from the 2015 to 2017 models consists of two screens whereas the upper display from the 2018 model consists of one screen, how then will ECU/BIU/whatever know how to change the display parameters from two screens to one?
