The SC-MT800 System Information Display shows you what gear you're in, has a battery level indicator, charging port, synchronized shift mode display and also doubles as a Junction A - it has 3 e-Tube ports for you to connect Di2 components to it. The displays lets you charge the system and also connect to it using Bluetooth and ANT+. It is usually installed on mountain bikes.
If you're thinking of using this display on your road bike to replace your Junction A (SM-EW90 / EW-RS910) and Wireless Unit - you can! Note that you can only have one component with wireless/bluetooth functionality plugged in. If you connect both this and a Wireless Unit the Di2 system won't function.
