2018 Subaru WRX: iDoing Android Head Unit Plug-and-Play Install

Yes — you can install iDoing on the Filmed on a 2018 WRX (black knobs). John says 2016–2019 owners who asked about the newer dash are covered, including Limited cars with the 7-inch screen with a 13 min DIY job. On Tom's 2018 WRX, John pulls the factory radio (four 10 mm bolts, including hidden side bolts), transfers the hazard.

Overview

John installs a new iDoing Android unit in Tom's 2018 WRX after a lot of questions about the 2016–2019 dash. Getting the factory radio out is a little harder than the older cars: there are 10 mm bolts on both sides plus two more behind a clip — four bolts total — and the side trim has to come out before the radio will slide free. A microfiber towel protects the trim. The hazard and MID buttons and the climate panel transfer onto the new bezel (four screws; one climate screw is blocked by a Subaru bracket, so he works it through the hole rather than forcing anything on someone else's car). Once the donor switches are on, the kit is largely plug-and-play. He did buy a USB adapter to keep the factory console USB, and FM will not work until you add the radio-antenna cable — contact the seller if it is missing, or use the Amazon antenna link in the description. The mic tucks along the A-pillar side and sounds fine. They test audio first, pair Tom's phone over Bluetooth, program steering-wheel hotkeys from a blank slate, and leave the screen protector on until the climate panel is no longer dangling. Tom is impressed; the IPS viewing angles are good, and you can swap to a car-oriented launcher if you do not like the default UI. The description's first Amazon links are the Metra USB adapter and the antenna cable; the iDoing product page, an eBay listing and an AliExpress link are also listed there.

Video chapters

Step by step

  1. 1

    2016–2019, including the 2018▶ 0:00

    John is installing on a 2018 WRX after a lot of questions about the newer 2016–2019 dash. He says a 7-inch factory screen, including Limited cars, is not a problem.

  2. 2

    Hidden side bolts and four 10 mm fasteners▶ 0:49

    This dash is a little harder than the older WRX radios: there is a 10 mm bolt on each side, plus two more behind a clip — four bolts total. Pull the side piece (he uses his nails), disconnect its wires for clearance, and release the top clip first so the lower one is easier.

  3. 3

    Radio out, protect the trim▶ 2:09

    Once every bolt is out, unplug the factory connectors — one latch takes an extra ten seconds if you miss the release button — and lift the radio onto a microfiber towel so the brackets cannot scratch the interior. The Android unit is actually lighter than the factory radio.

  4. 4

    Transfer the hazard switch and climate panel▶ 2:47

    The hazard and MID buttons and the climate controls move onto the new bezel. Climate is four screws. A Subaru bracket blocks one of them; he works the screwdriver through the hole rather than forcing or splitting a part on a car that is not his.

  5. 5

    Factory USB adapter▶ 3:27

    Power, audio, steering-wheel controls and the backup camera are plug-and-play. The factory center-console USB is the exception — he bought a Metra-style adapter and links it in the description (buy more than one if you have more than one USB).

  6. 6

    Tuck the microphone▶ 6:40

    The mic lead tucks along the left side and around so it sits in a clean spot. He is happy with how it sounds there.

  7. 7

    Test audio first, then Bluetooth▶ 7:21

    Leave the screen protector on for now. First check is radio and audio, because a bad speaker or harness connection is what you want to catch before the bezel is clipped in. They pair Tom's phone over Bluetooth and listen.

  8. 8

    Program steering-wheel hotkeys▶ 9:20

    The SWC screen starts as a blank slate. You add each key and assign the function, the same idea as programming a gaming keyboard. After that, the factory FM antenna still needs its own cable if the seller did not pack one — contact them, or use the Amazon antenna link.

  9. 9

    Peel the protector and check the screen▶ 11:11

    With the unit in the dash they let Tom, the owner, peel the screen protector. The IPS panel looks sharp off-axis. If you do not like the default launcher, John points to car-oriented launchers and his top-apps video. This 2018 is easy to spot from the black knobs.

0:00All right so today we have another brand new Android head unit we're gonna be installing it on

0:07on 2018 I know a lot of you guys are asking about the newer 2016 to 2019 and this is the

0:16new new so if you guys have a head unit like this it's not gonna be a problem if you have

0:21the seven inch it's not going to be a problem

0:23two for you limited boys.

0:25So let's get to it.

0:26This is my, this is my.

0:38Yo, I look it.

0:44Colors, I'm playing the screen,

0:45it's beautiful where it's like I can get.

0:47All right, looking kind of familiar.

0:49Now to remove this head unit,

0:50It's actually a little more difficult than the older ones

0:54because there's actually a bolt on the side, I believe.

0:56So we're gonna knock that out fast.

0:58Oh, this looks clean, though,

0:59but you get to make sure there's some bolts

1:01on the side that you need to get.

1:03So let's see if we can get to that angle.

1:05So there's a bolt right there.

1:06You can see a 10, just unscrew it.

1:09I believe there's one on the each side

1:11and then you can just pop it out with some clips.

1:13Seeing I got one bolt here.

1:14There's another bolt here I haven't removed

1:16but this piece right here just pulls right out.

1:18So I'm gonna pull it right out.

1:19one. I just use my nails. So, just the tool you gonna need. I'm gonna need to

1:24hands up.

1:29There you go. Make sure you disconnect the wires. So you just get them extra

1:30there you go make sure you disconnect the wires so you just get that extra

1:34clearance now with these ones they're actually kind of hard to remove so I

1:38recommend removing the top one first it just clipped in and then this one

1:42it's still kind of hard to hit so I like to pop this

1:44little thing out of then remove the clip from here just a little pro tip I know you

1:50you guys might have seen it but you get you have two more bolts right here two more

1:56bolts you need to remove right here and then the one so they have four bolts in

1:59total for this head unit kind of pain in the ass but you just pull this clip

2:01Kind of the pain in the ass,

2:03but you just pull this clip

2:04and it will expose at 10 mil.

2:06You can't miss it.

2:09All bolts are unplugged.

2:10You should be able to just pull it out.

2:12So, of course, you wanna unplug all this BS.

2:15This wire was kind of pain,

2:18but you just press this little button.

2:20Pain isn't like, it took an extra 10 seconds,

2:22but everything else was pretty self-explanatory.

2:25Notice I have the microfiber towel

2:27to make sure there's no scratches,

2:29but that's how the interior looks.

2:31Looking pretty simple, looking pretty simple.

2:32All right.

2:34All right.

2:35So, once you get this head unit, it is heavy, so.

2:38I think the Android head unit's actually lighter.

2:40So, if you guys are

2:44So, if you guys are talking about gains, get some weight reduction up in here.

2:47Something you have to transfer over, you see the switches right here, you have the hazard and the midfield display buttons.

2:51We're transferring it over to the new Android head unit.

2:54You also have to transfer over the climate controls, just four screws right here.

2:58Oh my gosh, it's like a Subaru man, it cucked you.

3:01They didn't have this bracket to block this screw

3:05Come on, man. It cucked me right here. So I try to unscrew it through the little hole, but look

3:10Look at that

3:12Just block it's just cock-blocking it so hard where I don't want to this is this is not my car

3:17So, you know, I want to take the spew

3:19We have to remove these bolts so I have everything in and everything's pretty much plug-and-play. This is the climate control

3:27Now the thing is I had to buy this USB so links in the description below if

3:33below if you're trying to still retain the USB and this goes right here in the

3:37center cubby hole a thing that I we're not gonna have XM anymore so

3:42pay attention to that and I actually had to buy this harness from this

3:49website didn't come with this adapter right here but usually if you order from

3:53a chicane or something they do include this adapter so just something to mind

3:59this is for your radio for FM and AM so it's kind of important but let's

4:03continue so I'll link the description on this and this just in case you want so

4:09we've got the head unit right here with a 2016 1718 19th they and use this

4:15vent design a way you can tell is if you have a silver bezel now this is the

4:19Android head unit it comes with its own bezel but the the 15s they don't have the

4:24silvers 16 1718 it has it and they actually have their own vent designs a

4:29little bit different so with this it's actually just clipped in you the way

4:30So with this, it's actually just clipped in.

4:33The way I do it is you wanna start

4:35with this very corner one,

4:36and you wanna tuck it right here.

4:38So you wanna start from below,

4:40and I don't know if you guys can get a good angle,

4:41but there's four clips right here here.

4:43And you, I mean, use your imagination.

4:45It's like four clips.

4:46How do you get clip on?

4:49You wanna, it does require some finesse.

4:52So you can just click, so it's clicking in

4:54and you can see it's kind of overhanging right now.

4:56And then you want to clip at the last two.

4:59See, you get a good angle of that.

5:02you want to kind of bend it and then just push it in and this is snug like OEM

5:09fitment now get a good look of the angles look at that flush beautiful CNC 3D

5:18but it's in and it's nice oh my goodness so what's to come so the next thing I

5:27want to do is install this these bad boys for bolts you just kind of it in right

5:31For bolts you just kind of bolt it in right here

5:33and you're set.

5:36Boom.

5:37But you need the four screws.

5:39You need the four screws.

5:42And then it's kind of looks like something like that.

5:44Wow. The 18s.

5:45have this nice black vent.

5:47Subi speed sells these for a really expensive.

5:50So, instead of buying it from Suzy,

5:52just trade in your car and then just get a 19 or 18.

5:57All right, guys, I got the two bolts installed.

6:03all I have to do is plug it in and we'll see something that's definitely not

6:08going to work right now is definitely the radio I have to top into the to

6:13get some power into it other than that it should work it's pretty much

6:18plug and play right now besides the radio right so I have the antenna plugged in

6:26right here and I also have the microphone and usb's now as you can see right here

6:31Now as you can see right here,

6:32the USB's are plugged in right here.

6:34I have one with the adapter.

6:36I actually have another one,

6:37because this one comes with two through the glove box.

6:40As far as the microphone hookup,

6:42if you move to the left with me,

6:44see right there this is where I have it

6:46and I tucked it in and it goes all the way around

6:49to here so this is where I have my microphone and it sounds pretty good so it

6:55uses two microphones one right here and one right there to cancel and try to just

6:59pick up on the driver's

7:02other than that we're just gonna plug it in hopefully it works let's do it

7:07the big reveal first boot up we have an audience I still have the so it's

7:17turning on, the first thing you definitely want to test out,

7:21remember there's this little screen protector

7:22so it looks kind of bump, but the first thing

7:24you want to test out is radio and audio, audio for sure,

7:28because sometimes if you have a car

7:30you have a car has a different amp and stuff you're gonna get no sound follow

7:34up by that you definitely want to check out the steering wheel controls usb

7:37access navigation and that goodness all right so we just need to plug in that

7:42radio adapter in the back and radio works with you have to metadata and

7:46everything sounds pretty good it probably sounds better than the stock unit the

7:49stock unit amp is not very good but radio quality is not the best so Bluetooth

7:56quality is also not the best about that there's some compression there but I'm

8:00just going to sound a lot better than radio so to have you can set up your

8:04Bluetooth through this thing right here we just set up Tom's phone right

8:12so we're just gonna have to go to the Bluetooth app so for you to play at your

8:16Bluetooth music you actually have to go to the source and the source is right here

8:19Bluetooth music play anything you want I'm gonna play a non-copyrighted song so

8:24that way you don't get this guy this guy knows things that's the AC now bro I

8:30forgot I don't have it on we haven't set this yet but we'll do this you're going to

8:43get used to tapping instead of volume sounds good so these units generally put

8:54more power into the speakers so big enough power it actually kind of wakes

8:59up your original speakers he knows his car set up more than me might sound the

9:03same it might sound not we actually have another head unit right there we can

9:06compare this if we want we could do an audio comparison see which one sounds

9:10better because it's like the exact same unit but yeah clean steering wheel next

9:15off we need to do is doing the wheel keys for the steering wheel so wheel

9:20key studies right here you click on this it's a blank state if you know

9:24about gaming keyboards and stuff you have to to set your own

9:27hotkeys and stuff so right here I'm gonna hit the plus sign

9:31it automatically reads now there's a short click and there's a long click for a

9:36short click let's a volume what about a long click that's kind of up to you so

9:42then we do a a short one again for volume down there you go right it

9:49will be skip right so how it is factory so we do the next song alright so I

9:56set up all these keys and I did just show the short clicks actually haven't done

9:59this one so I showed the last one right here so this one's the mute I believe

10:04right so let's go find the new icons very intuitive and there you go here all

10:10my hotkeys they're all short presses but you can do later there you go so if

10:16I go here lower volume set you want to change your Bluetooth songs you're

10:22good if you want to make your own you're good so everything is working right now

10:28there's nothing no no weird anom

10:38you go it's charging and now he also has another USB is a brilliant it's

10:43brilliant so this is plug-and-play just for if you don't the FM I had to use my

10:49own cable you have to buy it here if you don't have one but contact the

10:53seller if they don't have it. They should but if they don't it's there do you have

10:58any questions no I'm thoroughly impressed thoroughly impressed okay we'll do

11:03some sound comparisons and like it and I'll just give this a full review after

11:08we make it look nice and pretty because right now we still have the climb

11:11control kind of dangling yeah alright so we have it in why don't you do the

11:16honors since you're the owner's you want to take this off so-so we can

11:19actually use the touchscreen while being glitchy and I'm failing I just got my

11:26nail you cut your nail oh my god you got to start

11:29for you there you go the ASMR moment alright yo I

11:37looking man that's good that's home screen the colors I'm telling the screen
