NTG6 Map Code

Generate the map license key your NTG6 car asks for during a USB navigation update. NTG6 codes are written by hand rather than issued instantly, so this page also covers the delivery window, the navigation entitlement that imports often lack, and the region rules.

What is NTG6?

NTG6 is the first generation of Mercedes-Benz MBUX, launched in 2018 with the W177 A-Class. It replaced the older COMAND NTG5.5 across the volume models from 2018 on. Also called MBUX Gen 1 or MBUX 1.

Over COMAND NTG5.5, NTG6 brought a touch-capable center display that is landscape on most models, the first "Hey Mercedes" voice assistant, two driver-configurable widgets with customizable home screens, augmented-reality navigation on select models, and a touchpad on the center console in place of the old COMAND rotary dial.

Use this page if your MBUX Gen 1 car asks for a Map License Key, Navi PIN, Activation Code, or PIN code during a USB navigation update.

How to identify NTG6 in your Mercedes

The fastest check is our Car Lookup. The visual cues:

• Two horizontal screens side-by-side behind one glass panel (instrument cluster + center display)
• "Hey Mercedes" voice icon in the bottom-left of the center screen
• No rotary COMAND knob. Only a touchpad on the center console.

How to run an NTG6 map update

1. Get your VIN and region. Both on the data card or service booklet.
2. Create the USB using DLM. Pick NTG6, the correct region, the latest compatible map version.
3. Insert the USB, start the navigation update from the menu, wait for the Map License Key prompt.
4. Generate the NTG6 code below matching the version and region on screen.

NTG6 region compatibility for imported cars

NTG6 head units are region-locked at the factory. If your car's region is Korea, Southeast Asia, Japan, or China, parallel imports included, it will not accept a map from another region such as Europe, Africa / Middle East, or North America. The car rejects the map however the code was generated.

To install a foreign-region map on an Asian-region NTG6 head unit, you have two options:

• Change the head unit region through a specialist service. Search "Mercedes NTG6 region change".
• Replace the head unit with one from the target region.

You can still order the code before that work is done. Checkout adds a €50 non-refundable handling fee for a car from Korea, Japan, Southeast Asia, China, or Taiwan buying a foreign-region map, and the map still won't install until the head unit is changed. We flag the same constraint in the code-generation dialog. Check your region before you buy, because we don't refund codes bought against it.

NTG6 common problems

"USB stick is not valid" even though USB is correctly prepared

Almost always a region mismatch. The USB region must match the head unit's factory region. The Car Lookup confirms your car's region from the data card.

Navigation menu does not appear on the display

The car is missing the navigation entitlement on Mercedes' side. A map code can't fix that. Without the entitlement, the navigation app is hidden.

In supported countries you can add the entitlement through the Mercedes Me app. Buy the entitlement before buying a code. We can't refund codes for cars without it.

If Mercedes Me doesn't offer the entitlement in your country, email contact@mbretrofit.it. We'll check if a workshop activation is possible for your VIN.

Update interrupts midway through install

NTG6 maps run 8 to 15 GB and the install takes 45 to 75 minutes. Mid-install failures usually mean:

• Battery voltage dropping. Keep the engine running or use a battery maintainer.
• USB stick going to sleep. Use a USB 3.0 stick from a reputable brand.
• Doors opening or keys removed. The car reads these as cancel signals.

"Map version not supported" means the firmware is too old

NTG6 firmware caps the max map version. If the car rejects the newest map in DLM, your firmware is older than the map. Get a workshop firmware update, or pick the previous map version DLM allows.
