This page describes how to install the Di2 Information Displays SC-MT800 / SC-M9051 and pair them for the first time.
System Information Display - Junction A
The SC-M9050 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 components to it.
It supports both 31.8mm and 35mm diameter handlebars.
If you're thinking of using this display on your road bike to replace your Junction A (SM-EW90 / EW-RS910) you can - however.. this component does not feature wireless connectivity and the newer SC-MT800 and SC-M9051 are much better options.
Newer and better alternatives
The SC-M9050 is the older version of Shimano's information display. The current SC-MT800 and SC-M9051 displays are your go-to display if you're buying one now. On top of the functionality of the SC-M9050, these two units also add wireless (BluetoothLE / ANT) connectivity.
