Turn on the KT‑20 console and navigate to . Note the firmware version. If it is earlier than V2.0, proceed with the update. kt20-y-multi-v2.0 update
Updating to the KT20-Y-Multi-V2.0 is a straightforward process that can be completed in a few simple steps:
This occurs if the internal display drivers fail to map to the video output lines. Disconnect all HDMI, VGA, or auxiliary cables. Power cycle the module and use the original factory remote control or dual-control mouse mode to toggle the output source back to default.

The "Y-Multi" moniker refers to the dual-processor architecture (Cortex-M7 for real-time control + Cortex-A7 for Linux applications). V2.0 unifies these via a shared memory bus. This allows users to run Python ML models (TensorFlow Lite Micro) directly on the sensor data before deciding which radio to transmit on. For example, you can now filter out false motion alerts on the A7 core without waking the M7 core, saving up to 60% battery life in remote deployments.

Improved CAN-FD and DoIP protocol stability for newer European and Asian vehicles.
While OBD reading is convenient, Bench mode offers a safer, more stable environment for flashing updated V2.0 protocols.
