CANchecked E46 M3 / 3-Series MFD28 Multi Function Display | 2.8" Gen2 (LHD)

The CANchecked BMW E46 3-Series / M3 Multi Function Display - 2.8" Gen2 (LHD) brings modern data monitoring and motorsport-level functionality to one of BMW’s most iconic platforms. Designed specifically for the E46 chassis, this system integrates directly into the factory interior, replacing a dashboard vent with a high-resolution display that delivers real-time access to critical engine and vehicle data.

Unlike traditional gauge solutions, the CANchecked system taps directly into the vehicle’s CAN Bus network, allowing it to read the same data the ECU processes. This provides faster, more accurate data compared to OBD-based solutions while unlocking a significantly wider range of parameters. The result is a clean OEM+ installation paired with advanced performance monitoring typically reserved for dedicated race displays.

Built around a vibrant 2.8-inch touchscreen display, the system offers multiple configurable pages and layouts similar to a smartphone interface. Drivers can monitor key engine vitals, performance metrics, and diagnostic data in real time while also logging information for later review. Whether used for daily driving, tuning, or track applications, this display delivers the insight needed to better understand and push the limits of the E46 platform.

The CANchecked E46 display is far more than a simple performance meter. By accessing the CAN data stream directly through the vehicle, it opens up a wide range of ECU data channels and presents them in a format that is easy to read, customize, and use. With analog inputs for external sensors, fault code reading and clearing capability, warning functions, and configurable display layouts, this system gives E46 owners a powerful OEM-style solution for both street and performance use.
