SC-MT800 / SC-M9051 System Information Display installation guide
This page describes how to install the Di2 Information Displays SC-MT800 / SC-M9051 and pair them for the first time.
This Di2 information display is not only for use on mountain bikes or road bikes - it is also common on e-bikes.
Alternatively you can use the slightly slimmer SC-S705, but the display is arguably prettier and has more features.
If you've been trying to pair one of these to a mobile phone you may have run into the issue of the 'C' (connection mode) not showing. Some of these units do this, depending on the firmware version. This generally isn't a problem, because they do actually go into connection mode. They just don't show it.
I have written more on this in the SC-MT800 Installation guide.
