    Exceptional customer support

    Package arrived in 2 days, beautifully boxed. I had a slight issue getting the factory AUX to activate, messaged SyncSonic support on WhatsApp, and they sent me a video showing exactly how to enter the engineering menu. Brilliant service.

    Original reverse camera retained!

    I was thrilled that I didn't have to wire in a new reverse camera. The LVDS cables pull the original factory reverse camera feed right onto the new high-res screen seamlessly.

    Parktronic radar overlay is brilliant

    When I put the ML in reverse, the screen automatically switches to the camera, but it also overlays a digital graphic of the car reading my original factory parking sensors. Awesome integration.

    Android 15 is exceptionally stable

    Running live OBD2 engine telemetry via Torque, streaming HD music, and running Waze simultaneously on the A18 PRO model. The system hasn't crashed or hung up a single time.

    Solid mounting hardware

    The custom bracket that comes with the screen bolts securely into the original factory mounting holes. The screen is rock solid and doesn't vibrate or shake at all over rough UK country roads.

    Highly responsive touchscreen

    The capacitive glass feels premium. Swiping through the app drawer and pinching to zoom on satellite maps is incredibly fluid without any frustrating ghosting.

    Massive 128GB local storage

    Downloaded massive offline map areas for a European road trip in the GL, plus gigabytes of Spotify playlists. The eMMC storage is very fast and I still have tons of space left over.

    Flawless GPS lock

    The magnetic GPS receiver works flawlessly. I mounted it right underneath the plastic top-center speaker grille on the dashboard. It locks onto 15+ satellites instantly with zero dropouts.

    Retains all factory air suspension controls

    I was worried I wouldn't be able to see my Airmatic suspension settings anymore. Because you can switch back to the original Mercedes NTG screen with one tap, absolutely nothing is lost. Fantastic engineering.

    A6 PRO base model is incredible value

    I didn't need 4G or crazy RAM, just wanted Wireless CarPlay for my daily commute. The A6 PRO quad-core handles it perfectly. Very cost-effective way to get modern navigation in an older Mercedes.

    Brings the ML63 AMG into 2026

    The ML63 is a beast, but the interior tech was lacking. Slapping this massive, sleek screen in the dash completely rejuvenates the cabin. The UI themes resemble the newer GLE MBUX system.

    Tom A. (Cardiff)

    10 Jun 2026Verified

    Split screen is perfect on the wide display

    The ultra-wide aspect ratio is practically made for split-screen. I have Waze running on the left 70% of the screen, and my media player on the right 30%. Incredibly functional layout for long trips.

    Craig F. (Liverpool)

    Bluetooth calls are crystal clear

    Mounted the supplied clip-on microphone near the rearview mirror. Callers say they can hear me perfectly at 70mph, the echo cancellation software on the Bluetooth 5.0 chip does a stellar job in a large cabin.

    Installation is very straightforward

    Taking the W166 dashboard vents out is the hardest part, but the wiring behind the radio is strictly plug-and-play. Very rewarding DIY project that saves hundreds on professional fitting.

    Instant boot is amazing

    I turn the ignition on my ML250 and the screen wakes up in literally 1 second. No annoying loading animations every time I jump in. It picks up exactly where my Spotify left off.

    Zero lag with 8GB RAM

    I went for the highest spec version. Bouncing between the factory NTG menu, Apple CarPlay, and split-screen Android apps is buttery smooth. The processor handles heavy loads brilliantly.

    4G LTE is a lifesaver for family trips

    Routed the 4G SIM card slot into my glovebox. Dropped a data SIM in there and the car now has standalone internet. Waze gets live traffic and the kids can watch YouTube without draining my phone's hotspot.

    Fantastic anti-glare IPS panel

    The W166 has large windows and lets a lot of sunlight in. The anti-reflective coating on this glass is excellent, keeping Google Maps completely visible even on bright summer days.

    Steering wheel buttons retained

    The supplied CANbus harness is brilliant. Volume controls, track skipping, and phone answer buttons on my steering wheel communicate with the Android interface instantly. No messy programming required.

    The X73 PRO 360 camera is brilliant for a massive GL

    The GL is a boat to park in tight UK spaces. I upgraded to the X73 tier and fitted the 360-degree cameras. The high-res ultra-wide display shows the top-down view flawlessly. Highly recommended for the X166.

    Harman Kardon integration is flawless

    My GL450 has the premium Harman Kardon Logic 7 fiber optic amp. Bought the optional MOST decoder box with this unit. It plugged straight into the orange optical cables and the sound quality is actually punchier than stock thanks to the 32-band DSP.

    Joystick works perfectly!

    I hate leaning forward to touch screens while driving an SUV. The fact that the original Mercedes rotary command dial works flawlessly to navigate Apple CarPlay and the Android menus is an absolute game-changer for safety.

    Mark S. (Manchester)

    Stellar system, took a minute to activate the audio

    The computing power on the Octa-Core is immense. Just a note for DIY installers: you must go into the NTG engineering menu (holding Hangup + 1 + #) to enable AUX audio so the Android sound routes to the factory speakers. Once done, it's perfect.

    David W. (London)

    Absolutely transforms the ML350 interior

    The original NTG 4.5 screen looked so small surrounded by the massive plastic bezels of the W166 dash. This ultra-wide screen fills the space beautifully. Switching back to the original Mercedes menus to check my vehicle settings is instant and seamless.
