# NTG7 Map Code Canonical URL: https://mbretrofit.it/guides/map-code/ntg/ntg7 Description: Generate a VIN-validated NTG7 map activation code for Mercedes MBUX Gen 2 (W223, W206, W214, W167 facelift, EQS, EQE). Full region coverage and step-by-step update guide. ## What is NTG7? NTG7 is the second generation of Mercedes-Benz MBUX. It launched in 2020 with the W223 S-Class and rolled out across the line-up through 2022–2024. Also called MBUX 2 or MBUX Gen 2. What NTG7 adds over NTG6: * Larger tablet-style portrait displays * "Hey Mercedes" voice assistant with neural-net language model * Over-the-air firmware updates on supported model years * Higher-resolution map rendering and 3D building data * Augmented reality navigation overlays Use this page if your MBUX Gen 2 car asks for a **Map License Key**, **Navi PIN**, **Activation Code**, or **PIN code** during a USB map update. Image reference: Double-check your head unit matches the photo below. ## Mercedes models that use NTG7 NTG7 / MBUX Gen 2 is installed in: * **S-Class.** W223 (2020+) * **C-Class.** W206 (2021+) * **E-Class.** W214 (2023+) * **GLE / GLS.** W167 facelift (2023+) * **EQS.** V297 (2021+), EQS SUV X296 * **EQE.** V295 (2022+), EQE SUV X294 * **SL.** R232 (2022+) * **AMG GT.** R190 facelift, X290 4-door variants Not sure if you have NTG7 or NTG6? Run the [VIN lookup](/guides/car-lookup). It reads your data card and reports the NTG version. ## How to identify NTG7 in your Mercedes The fastest check is the [VIN lookup tool](/guides/car-lookup). Two visual cues: * **Portrait-orientation centre display** taller than it is wide * **No physical COMAND rotary dial.** NTG7 is fully touchscreen + steering-wheel touchpad. ### VIN lookup An interactive vehicle lookup is available on the canonical guide page. ### Video tutorial A generation-specific video walkthrough is available on the canonical page. ## NTG7 map update — quick path 1. **Get your VIN and region.** Both on your data card. 2. **Create the USB with DLM.** Follow the [DLM guide](/guides/map-code/dlm). 3. **Insert the USB and start the navigation update.** Wait for the Map License Key prompt. 4. **Generate the NTG7 code below** matching the version and region the car shows. Enter your VIN in the map-code flow to confirm the compatible navigation system, region, and version. > **NTG7 codes are manual.** Our team generates them. Expect 20 minutes to 3 hours during GMT+2 hours per our [Terms of Service](/terms-of-service). Code shows on this page and arrives by email. ## NTG7 OTA updates vs USB updates NTG7 supports over-the-air (OTA) map updates through Mercedes Me on supported model years and regions. Only while the map-data subscription is active, usually 3 years from new. After that, you're back to manual USB. This page covers the manual path. If Mercedes Me still does OTA for your car, you don't need a code from us. The prompt only appears on manual updates. ## NTG7 common problems ### "USB stick is not valid" even though USB is correctly prepared Almost always a region mismatch. NTG7 is strict on regions. Korean, Japanese, and Southeast Asian market cars won't accept EU or US maps without a head-unit region change. If your car region is Korea, Japan, or SEA and you want a different region's map, our service won't work. The head unit needs physical reconfiguration first. Email [contact@mbretrofit.it](mailto:contact@mbretrofit.it) if unsure. ### Update reboots midway through install NTG7 maps are 15–25 GB. Install takes 60–90 minutes. Mid-install reboots usually mean: * **Car battery dropping.** Keep the engine running or use a battery maintainer. * **USB stick going to sleep.** Quality USB 3.0 sticks (SanDisk, Samsung, Kingston) avoid this. * **Driver opening a door or pressing a button.** Leave the car undisturbed. ### "Navigation entitlement missing" — no navigation menu after install Some imports lack the navigation entitlement on Mercedes' side. Buy the entitlement through the [Mercedes Me app](https://www.mercedes-benz.co.uk/passengercars/buy/digital-extras-overview/apps/me-app.html) where available. Without it, the navigation menu is hidden and a map code won't fix that. Check the entitlement before buying a code. We can't refund codes for cars missing it. ### Code rejected — version newer than firmware allows NTG7 firmware caps the max map version. If the car rejects the latest map, your firmware is older. Either: * Have a dealer update the head-unit firmware first * Pick the previous map version in DLM that your firmware supports The [Map Coverage](/guides/map-code/coverage) page lists firmware-to-map compatibility. ## NTG7 map coverage by country The complete country coverage is available on the canonical page. ## Frequently asked questions about NTG7 ### How long does the NTG7 map update take in the car? 60 to 90 minutes for a full region map. Keep the car running on idle or on a battery maintainer the whole time. ### Can I get a free NTG7 map update? Only through Mercedes Me OTA, and only while the map-data subscription is active. After it expires, every NTG7 map update runs the activation-code path. ### My W223 / W206 / W214 — same process? Yes. Every NTG7 model uses the same code-based activation. The prompt screen looks identical across S-Class, C-Class, E-Class, EQS, EQE, etc. ### Why does NTG7 take longer to generate than NTG5 or NTG6? NTG7 codes aren't fully automated on our side. Each one runs through a team member. Expect 20 minutes to 3 hours during our hours. ### My imported Korean / Japanese car — can it install an EU map? Not directly. Asian-market NTG7 head units need physical region reconfiguration first. The activation code alone won't bridge it.
