Yes — you can install Dasaita on the 2013–2015 Mercedes-Benz E-Class W212 with NTG 4.5 with a 23 min DIY job. Retain the OEM radio: daisy-chain the Dasaita harness (move the pink fiber optics), mount the 12.3" screen, set factory code 190627, then fix audio via AUX + external amp and OEM camera mode.

Overview

One of John's harder installs. You keep the factory Mercedes radio and fiber optics, add a huge 12.3" Dasaita screen, and pass audio through AUX. Most of the pain is trim (vent tabs) and troubleshooting: factory password 190627, TGW external amp ON, AUX position = 8 on the second tab, and reverse camera set to OEM — otherwise you get no sound or "no signal" in reverse.

Step by step

  1. 1

    Set OEM radio to AUX first▶ 1:30

    Select AUX on the factory unit before you tear into the dash so audio routing is ready after the swap.

  2. 2

    Remove the upper trim and factory screen▶ 2:00

    Pull the top piece (clips), remove two T25 screws, pull the OEM screen and unplug its harnesses.

  3. 3

    Drop the vent / clock panel▶ 2:49

    Push the hidden tabs on each vent toward the clock, pull the panel and unplug three harnesses. John calls this the hardest part of the install.

  4. 4

    Unbolt the OEM radio (T20)▶ 4:08

    Two long T20s up top — support the unit so it doesn't drop. Push the metal retaining clips down, free the small wire, pull the radio and unplug.

  5. 5

    Daisy-chain the Dasaita harness▶ 5:25

    Keep the OEM radio. Move the two pink fiber-optic leads into the new harness (listen for the snap), then plug OEM ↔ Dasaita ↔ radio so everything stays snug.

  6. 6

    Fish the harness and power-test▶ 6:47

    Skip a full glove-box teardown if you can — fish the main lead down and back up behind the dash. Hook GPS and camera leads, confirm the new screen powers.

  7. 7

    Enter factory settings (190627)▶ 9:13

    Code is 190627. Select NTG 4.5 / half-screen as applicable, then reassemble trim in reverse.

  8. 8

    Fix no-sound: external amp + AUX▶ 10:37

    On the OEM side (red + 1 + #): Hardware settings → TGW parameters → external amp ON, AUX audio ON, then System Reset (not End). On the Android side: Audio → count to AUX row 8 on the second tab; set AUX position to 8.

    Warning: If TGW is left on internal amp you get silence. Always System Reset to save.

  9. 9

    Fix reverse camera "no signal"▶ 14:45

    Settings → System → Camera selection → OEM (not the default Aftermarket).

  10. 10

    Pair CarPlay / Android Auto▶ 15:51

    Pair Bluetooth normally; ZLINK / Phone Link launches CarPlay or Android Auto. OEM menu still works via the controller wheel when you're not in AUX.

0:02All right, we get a T-25 all out of the mess. You guys to make sure audio is working

0:09So we ran into this issue

0:11I just want to make sure you guys something to the issue

0:24What's up guys? It's your boy. We're gonna be doing an install on Mercedes e-class

0:29This probably would be my most difficult install, but if you know

0:34Happy holidays

0:35Anyways, we have the decided ahead unit right here kind of pre-unbox it a little bit

0:40Now this is gonna show you an instructions on how to do it because the Mercedes is gonna be a little bit more

0:45Involving but you're gonna definitely need the pass code and everything and just want to say

0:49Right off the bat. Do you guys see the code? It is

0:53190627 so if you're there for the password, there it is

0:57Got the good foam and then we have the head unit itself with the clamshell

1:04Well the shell piece

1:07To mount the new screen and a huge amount of harnesses

1:15Yeah, this is a huge screen massive actually, so it's gonna be

1:21Pretty involving install

1:24All right, so before we start something you can do to speed up the process

1:30It's better to put it in ox mode, but if you don't have an ox mode, there's a workaround

1:35It's just the way you should be doing this is having an ox mode first

1:41All right, so you're going down to ox

1:45Have it selected that way when we

1:49Switch it over all should be well. So I have my

1:53Father-in-law, he's gonna be helping me with this one. He's a

1:57Expert on his car

2:00So underneath here, there's gonna be two hooks that we're just gonna pull down

2:05Gonna remove the top

2:07These are just held by clips

2:13And this is just held by plastic clips and then you can unscrew these with some torque screws

2:22All right, we get a T25 to remove these two screws

2:27Just pull the screen out and then unplug the back

2:34harnesses

2:42These are on pretty good

2:44There you go

2:46My dad knows I'd do it better than me

2:49All right, so we expose that the next thing you want to tackle is there's gonna be these hidden

2:54screws right here

2:56We're going to have to

3:02You'll see these tabs on the side of each little vent and after that you'll be able to pull it out

3:08It's gonna be hard to see but you want to push these

3:14You'll see the tabs that finally it's just a little dark. You want to push it towards you

3:20towards the clock

3:22It's the best way to describe so which I can show you a clearer image, but

3:28Just how it is get the light and pull it towards you

3:39A whole lot of finessing

3:41It's okay, and then we unplug these three little harnesses right here

3:49This is the hardest part of the install just removing this piece

3:56After that everything's pretty easy

3:58So now we can access

4:08Okay, I then these are some T20s

4:13That you remove from the top some T20s. There's two right here

4:22You generally need to use them kind of like a ratcheting system

4:25Yeah, there you go. So you crack both of those loose and then you'll be able to remove the radio. That's it

4:36All right, so these two bolts are these two screws are actually really long so

4:41We are using this tool to kind of keep it up. Well, I'm screwing it because if you don't do that, it just fell straight down

4:48So yeah, just these two screws

4:51All right, so after we push

4:52We took the screws out. We actually had a push is like metal clip down or otherwise it doesn't go down

4:59So if it if it's not pulling out is should it require a lot of force it's just those two bolts are holding it

5:05So push these little metal clips down, and there's also a little wire right here that we need to remove

5:11And then the whole thing should just pull out and you just unplug everything

5:16That's something I recommend is maybe put

5:20Some towels or something to protect the interior a little bit

5:25All right, so after you pull it out there's this main connector and

5:30This is the one that we want because we're still retaining the OEM head unit. We are just

5:36Adding another functionality to it. So we just have to remove this clip

5:40Then we're gonna daisy chain it to the new one

5:47I'm Mercedes has this really robust clip

5:50that

5:53Make sure everything is nice and snug

5:56I've actually done some BMWs too that has these extra clip

6:01And yeah, my dad got it real good

6:05I need to get there are two fiber yep two fiber optics on here. You'll see right here

6:13They're in this pink color and we transfer to the new harness

6:18All right, so we unplugged it it comes in this pair and you plug it into the new harness

6:25Just like that you'll hear a snap so

6:28This is the

6:29New harness from decided and we're gonna be plugging it all into the OEM head unit the new harness

6:38Okay, okay

6:40Same with this now. We're gonna the OEM harness

6:44Now it's gonna be plugged into this new one

6:47All right, so for the harness you can remove the glove box

6:50We are trying to fish it because there's so many screws for the glove box that we just don't want to deal with

6:55So we just have a

6:58Wire coming from the top to the bottom and we are just gonna try to fish this main harness over

7:05You don't have to put everything. There's just one cable really with the head on it that we taped

7:14And it's just a matter of fishing that wire up

7:22All right, so we successfully routed through the cable we went down

7:27Then we went back up here and we pulled the cable and then we routed

7:33behind here

7:35So we had the wire kind of fish through here and then it shoots out through this

7:46All right, so after you kind of fish all the cables up

7:50We are plugging in and make sure it all works

7:54This one this white one right here the small one we have it hooked up to the top

7:59And then there's a little GPS antenna as well

8:02That you hook up right here

8:04This white wire we have it hooked up for

8:08That teal cable in the back because see that this one right here

8:13To the camera, I believe

8:17Oh, it's blinking red

8:19It's getting power

8:24And we are just testing this so we will unplug it because we have to put the trim

8:29So this is just a test. Oh, it's already on

8:32What the heck

8:34How's already on our info

8:52Okay, so you're not dry, right?

8:55So we have to see like this

8:57See?

8:58Oh, it's weird. I like it

9:00It's happening

9:05Oh, sorry about the glare

9:07Factory

9:08But I'm trying to get it without the glare. I need to my polarize the factory

9:13The code is

9:1519

9:170, 6, 2, 7

9:2219

9:25Still

9:276, 2, 7

9:32Okay

9:34God is blame

9:37Okay, so we just select the

9:42We are 4.5

9:47Half-screen that looks

9:57What happened?

9:585.8, that's a

10:017-inch screen

10:03That's 17-8

10:07This is a good time, right?

10:08Yeah

10:17Oh, there you go

10:19High-five

10:21All right, we're just going to wrap everything back up and reverse

10:25Pretty self-explanatory and then we're going to go through the head unit, so

10:30All right, so after we wrap up everything

10:32There's something I need to show you guys to make sure audio is working

10:37So we ran into this issue

10:39Just want to make sure you guys don't run into that issue

10:43All right, so to go into oh if you can hold that wall

10:48If you can go to this menu right here by pressing the red button

10:531 and the pound sign

11:00Because we were trying to enable ox and when we enabled the ox

11:05Um

11:06We didn't need to do enabled the ox to get it to work

11:09But we resetted it and then it actually got rid of our settings

11:13So we want to go hardware settings and tgw parameters

11:19Make sure external amp is turned on

11:24And I think the

11:27That's that's all you need to take a look at

11:30I don't think you need to take a look at any of these but

11:34Make sure the external amp is turned on

11:38Um, that was their parameters here

11:41We have ox audio ox turned on as well

11:45So make sure that's turned on

11:48But yeah, we were reading to issues where this

11:52TG parameters

11:54The external amp was it was internal amp and we had no sound and it was driving me crazy

12:00Um

12:02Yeah, and after you do all that

12:05You hit system reset don't hit end because it won't it won't save the the function out

12:11Another thing

12:13We want to take a look at is how do you get audio working for your android head unit side

12:20You want to go up here hit audio

12:23And you can count here one two three four five six seven eight

12:28So now we are an ox mode which will kind of bring up into this menu

12:33And you want to go to your settings too. I'm using the mouse wheel, but this is touchscreen go to system

12:39And this is to get the audio working remember how I counted one two three four five six seven eight

12:44go to ox position

12:45It was on the second tab so one two

12:48And we have it to eight said we have you're gonna have audio through this now

12:54Let's see

12:59So there's audio through this now. I don't know why the faders on the

13:13I need to see why the sounds that but that's how you get audio on the main system

13:19And you get apple car play and android auto

13:22Let me also go through some settings to if you don't have the ox position turn on go to factory. It was

13:31one

13:34One nine zero two six seven so one nine two six seven. Oh

13:42One nine zero six two seven one nine zero six two seven

13:48Okay

13:49go to

13:51So you're going to see all bunch of these options right here

13:54We kept it right there vehicles switch without

13:58We have automatic

14:00Other manual seats

14:02You want it if you don't have that ox you need to go into here and hit ox activate and go through that one settings when you hit the

14:10These three buttons and they enable that ox settings right there. So ox activate. We don't need to do it here

14:15For our 2013 Mercedes e-class we have this option right here

14:20So current selection is selected that

14:23Camper file protocol is right here

14:27After that there is one more settings. I wanted to show you guys that we were having issues with

14:32So I don't know like are the cars on so maybe turn the car on real quick

14:37When we have it in reverse it said no signal

14:42Let me show you guys how to fix that

14:45You go to settings go to system

14:49It was

14:52Camera selection. So you have three you can choose aftermarket OEM or 360 it defaults to aftermarket

14:58Which is weird but go to OEM and then you'll be able to fix that

15:03So there's the settings. I'm just gonna go through over the menus real quick. Oh, I can show that real quick here

15:09So here here are all the menus great

15:12HD video phone link mirroring

15:15Then so forth

15:18This is the original car menu and you can change this to an ultra-hour

15:23But using this wheel you will be able to this will act exactly like your OEM head unit

15:30Um, but remember you want to stick this to ox so you get some audio

15:34Also if you go to volume make sure it's boosted so you just get more audio going on

15:38Which is great here

15:41If you don't want to be that menu you can hold I believe you hold back

15:46It goes back to here

15:49You want to connect your phone

15:51After you connect your phone um

15:53I have Apple CarPlay. I'm gonna hook up my dad's phone. You want to do your phone

15:58All right, so we just connected it through bluetooth

16:01Bluetooth if I wish I can catch it you just pair it like a normal bluetooth device

16:05And you will automatically go to android auto. This is exactly what we want. This is very good

16:10All right, if you can do it the honors that

16:13Oh

16:22Now the screen's easier to see

16:25All right, everything works again. The sound was the biggest thing. I'm gonna go over it one more time from the top to the bottom

16:33You have navigation which it uses the GPS. We routed that GPS under here over there. So you can kind of see the puck right there

16:43and

16:44Yeah, it has its own little navigation system right there you get the music

16:51I haven't viewed it

16:55Everything sounds working there. You can skip and all that

16:58stereo controls are working, but I'm just

17:01Go through the menu phone connected. I have it hooked up to an s23 ultra. I also had it hooked up to an iPhone 15 pro

17:08Max no problem car play hooked up

17:12Easily car info is that little menu we were looking at earlier

17:17Um, yeah, it works. Uh, here's the audio

17:22So audio is working and if you want to go back just hold back

17:29It goes back to this menu right here settings

17:33We'll go that real quick video apps. Here's some apps if you want to check out the apps

17:38my dad does like using the

17:43Google offline maps, so that's something we need to play with zlink is the one we need for car play for me

17:49I just use car play and but he is he likes to do something different

17:54Some dashes right here. It actually does work. Let's see if

17:58That tar it toggles anything

18:01Into the show the rpm look at that. That's kind of cool

18:04RPM

18:07How did I get out of here?

18:09sport oh

18:12AMG e63

18:16You can see that or you can change it back

18:20So there's that option right there DVRs if you want to hook up a dash cam and that looks like it's it for all the

18:27Applications here. We've got theme settings. There is blue. So anything that matches this interior. I think

18:35I think this one kind of matches the whole it matches with the cluster. So let's let's keep it kind of similar to the way it was

18:44And we go into the settings here. We go to sound

18:47These are your equalizers. Nothing we need to really change their language

18:52Oh system right here in reverse camera hold the brakes

18:58There it is. We got the reverse camera in all its glory

19:02You can do note parking lines parking distance controls and stuff like that

19:08Again, if you were having camera issues make sure it's to OEM camera

19:13We had troubles with that

19:15So there's 360 cameras. There's a lot of things you can add you can mute it while you're reverse

19:19We don't want to do that aux position. We talked about a little bit earlier

19:23You want this to be on the this is the tab position. So there's like different tabs

19:28Media I believe is what the one it is because it's GPS satellite then media. That's why it's in the second tab

19:36Then this one is the rose eight rose down is the ox and that's what we have it right there unit temperatures

19:44We let's let's keep it Fahrenheit just to um we're here in America

19:48Select music app

19:50There you go if you want any of that

19:52We're not gonna mess with any of those settings. We'll keep it default navigation

19:57You can do the navigation all so my dad really likes the google maps

20:01So we can have it default to google maps or the one that came with the system

20:07All right, uh see

20:10Volume there you go. I just maxed everything out here

20:13Sound again the EQ we were talking about earlier language. This is how it looks like if you're interested

20:20I want to go too much time. You can do the 12 hour

20:24um

20:25See car time is it 528 528 so you can use it

20:28Let's use the car clock because it's gonna be more accurate and kind of match this one right there

20:33So that's good thing we did that system info

20:37If you need update all that goodness

20:40Android it's gonna be like your tablet android. Let's see if there's any system specifications and doesn't look like it

20:47There's brightness and all that goodness

20:50You can see your uh all this

20:53stuff

20:57Yeah, doesn't look like looks like uh the decided head units gives you about 50 gigs. Maybe it's a 64 gig

21:03Put a lot of movies in here if you wanted to there's also two micro SD cards

21:08If you want to put your micro SD cards to expand on the storage

21:12factory

21:13Okay, I keep forgetting the password. It's it uh

21:16one

21:179067

21:21and

21:22Here we're gonna go over one more time real quick. I kept this all default

21:27So I didn't change any of this stuff

21:30Make sure you get you get the stuff right there

21:35Vehicle

21:39This is the harming card in one gear selector mode

21:45front

21:46Plus speaker enabled

21:49All that goodness

21:52Ox if you don't have the ox enabled make sure you activate it here

21:56Card display that depends on your resolution. This goes all the way up to 720p on the 2018 models looks like

22:03Uh again 4.5. That's what we had

22:07Mike gain

22:09Custom exit time

22:11We're not gonna do anything that profile boot logo

22:15Uh, we'll keep it to whatever it was

22:17except

22:19You can import your own one so if you want your family picture or something like that

22:22You can do that there

22:24And yeah, that's that's it um apple car play android auto it's all here

22:30And you can play sounds at the same time

22:34This is a really cool head unit that integrates with the i would like to say mode selector right here

22:42But if you guys are interested in this product the cita has it here. I want to link the down links in the below

22:47Don't forget to do like comment subscribe if you have any questions in terms of troubleshooting

22:53Questions when it comes to what I think of this head unit audio quality honestly sounds identical

22:59So this is more just mirroring the screen up here and then passing it through through ox

23:03So the sound system sounds exactly the same doesn't improve it all but I think the sound system on this already sounds good enough

23:10But yeah, thank you guys for watching. I'll catch you guys in the next one. See you later
