Main Screen Retrofit to 9" with CarPlay
I learned a lot from this thread; running the AUX cable to AMI, problems with bluetooth, Fakra Y connector, etc..
I have two questions, I hope someone can help me out.
1. I ordered this Fakra Y connctor from Ebay, someone shared the link here. Did I order a right one?
2. I'm planning to use the factory GPS antenna because some folks here said it works much better. But, I don't know how to locate the factory GPS antenna.. no one talked about it. I guess I need to pull the cable out from the head unit or comand. Does anyone know what color the plug is or does anyone have a diagram?
My truck is 2015 GL450, I believe it's NTG4.5
Thanks in advance!
I'm in the middle of installing an Android 10 unit on my x166 and running into issues with the selector knob wheel thingie.
The instructions I have are a bit odd as there's a ground wire I need to attach to the radio chassis, which no one had mentioned previously in this thread. Regardless, that was perhaps the easiest part of the install.
I believe my issue is with a loose connection in the harness somewhere or a mismatch with the jumpers. My NTG type shifts from KF (which is what I need) to K9 when I connect the side plug (hazard / seat heaters / etc).Before I start playing with the jumper settings, I'd like to know what state the car needs to be in before doing so. My instructions are in chinglish and it's not clear if I need to disconnect my battery before doing so. Here's what the instructions state to do word for word:
"If you exchange AB plug connection, had to hard restart the stereo in order to trigger it as KF. It means totally power off your car, remove car keys, then remove both end of our power cable (include male end and female end) then remove car original cd player power cable. After done all, exchange AB connection, then connect all cable one more time, then totally power on your car to activate the new connection method.) If above two connections also can't show "KF" Then try bellow more 4 connection methods bellow:
AB-A B-A
AB-A B don't connect
AB-B A-B
AB-B A don't connect
Totally these six connection methods, one by one until your car can get "KF". "
When changing jumpers, what did you guys do to do this? Unplug the harness or unplug your battery? Wtf is a CD Player power cable??
thanks in advance!

someome shared a link in this thread which has very detailed information.

You can find AB-A... connection thingy here for your NTG version.
Helpful to me was to be able to trim some of the plastic under the stereo/above the climate controls( if I would have decided to do this earlier would have saved me atleast 30-45minutes of trying to put it all back together. This afforded the room to move the big plugs into this area and easily push the stereo back into it's place. There is a little noise when the volume is turned up and I have ordered a ground loop isolator to plug between the screen and aux media cable.
Note: I had to go to the factory setting and choose the correct NT4.5 full screen resolution. My screen came with the wrong setting and it did not work at first. But after that was figured out everything worked like a charm.
Only complaint I have would be the backup camera. When I put the vehicle into reverse it goes to the Mercedes factory screen backup camera, which is fine but then when i take it out of reverse it was go to the defaults Mercedes screen until I touch the screen again, It's a bit annoying.

This is my first post, and I know that I am in the wrong category. However, I'm considering updating the screen in my 2016 GLS X166. Does anyone know if the MEKEDE screens will fit/work?
On their store-site, they show compatibility with X166 2012-2015 on all of their screen. They don't seem to have any screens with compatibility for X166 2016-2019.
I really appreciate any help you can provide.

1) the control knob does not respond when you start the car, I have to go into the original mercedes screen, scroll with the knob, then go back to this unit and then the unit responds to the knob. really annoying. Anyway to fix this?
2) Alot of static radio noise. I have it hooked up thru aux in my center console. Does the noise isolator thing help?
3) Is there a way to control the radio from the new interface, or do i have to go back to the mercedes interface everytime for radio?
Note that I bought my unit last year, I don't know if there are any new updates if you buy today.
Despite reading all info I could find and trying to get round the complete lack of instructions I’d missed this step. Hopefully it’ll help someone else in future.
Also I was planning to order the 8 core model from 4x4shop.ca, until the sales guy told me that the unit cannot be used with GPS splitter, he told me there is no adapter for it. Any idea about this? I'd like to use the factory GPS antenna for a reliable signal. Actually half of the reason I buy this is for a decent GPS nav.
Thanks!

All connectors on these units are same as far as I know, and you can indeed get a splitter. I bought Fakra C male to 2 x female and then had to get a male to SMA Male to connect to the unit. If you can get Fakra to Fakra/SMA direct it avoid the extra cable.
1. When is mic used? - I can imagine 3 different way to receive/make a call a) NTG, factory head unit based call, I suppose the mic won't be used. b) phone connects to Android screen bluetooth. c) phone connects to Android screen Carplay (which mic gets used? iphone's or android screen's).
2. Best way to install it - hate to poke a hole on steering wheel boot. It's a very awkward place to work with, drill a decent looking hole that won't tear further might not be very easy.
-Thanks




The only issue is the overwhelming background music. However this is one of the better ones I’ve found.
I took several photos of my install of my amplifier/subwoofer install. When I tackle this project, I’ll post updates here also.
Be aware, the dashboard piece of the 12.3 looks nice but the mechanical parts of the vents barely work and feel cheap to open/close/changing air flow direction. The vents would actually close when turning the fun high. I ended up disconnecting the front "wheel" controls (one wasn't working at all) and tied the mechanism inside stuck open for the time being. They're sending me another part but doubt it will make a difference. They made me work for it too...
