Mercedes-Benz ML W164 / GL X164 9 inch Android Head Unit with Wireless CarPlay, Android Auto and 4G | IMHP94M164

Your iPhone joins CarPlay over Wi-Fi without a cable. Maps, calls and music appear on the 9 inch screen, and voice commands let you ask for directions or a song while you drive.

Android phones connect to Android Auto wirelessly too, putting Google Maps, calls and music apps on the dashboard.

The 9 inch QLED screen runs at 1280×720 behind G+G tempered glass. Its anti-glare finish keeps it readable in direct sunlight.

With an IPS panel, the screen keeps its colours from the side, so the front passenger can read it clearly too.

The AKM 7604 DSP gives you a 36-band equaliser, so you can shape the sound around the cabin and speakers of a large SUV rather than relying on basic tone controls.

The TDA7851 amplifier delivers 4x48W, enough to drive the factory speakers without a separate amp.

Fibre-optic, coaxial and RCA outputs let you add an external amplifier or processor when you want more from the system.

Two Bluetooth modules run side by side. The Qualcomm module streams music with aptX HD, and the Unisoc 5.2 module can connect to an OBD-II scanner or a dash cam while your phone stays paired.

Insert a standard Micro-SIM and the unit has its own data for live traffic, weather and streaming, without tethering to your phone.

Wi-Fi on 2.4G and 5G carries wireless CarPlay and Android Auto, and the unit can join a hotspot for updates and downloads.

The supplied GPS antenna lets navigation apps follow your position on the 9 inch screen, with live traffic over 4G.

Screen mirroring shows your phone's display on the head unit for apps that don't run in CarPlay or Android Auto.

Connect an external DAB tuner to add digital radio stations.

CANbus integration keeps factory features such as ACC and door reminders, and the steering wheel control adapter lets you change tracks and volume with your hands on the wheel.

A camera cable is in the box. If your car already has the original reversing camera, you'll need an adapter to keep it working after the upgrade; XTRONS ICE/ACS/FZMRM01 is compatible.

The Unisoc 7865 octa-core chipset (two A75 cores at 2.2GHz and six A55 cores at 1.8GHz) works with 8GB RAM and 128GB UFS 2.2 storage and plays 1080P video. A built-in gyroscope and inclinometer show roll and pitch in real time for off-road driving. The unit is rated from -30°C to +80°C.
