I really like my the SC-MT800 System Display installed on my Bianchi XR4. The display has 3 Di2 ports and clamps to my handles bars.You can get one from Universal Cycles for $90. It works perfectly with the Road Di2 components. The display comes on every time you shift or touch the mode button. I have the display timer set to 30 seconds ( via e-tube-project configuration). I was having problems with my Di2 battery being run down by a Shimano Di2 inline Bluetooth module, it wasn't shutting off at times. The MT800 connects to my phone or Garmin 1030 with no problems. Firmware updates are easy via e-tube-project.
The SC-MT800 System Display is the brains of Shimano's XT Di2 electronic mountain groupset, allowing you to view data, control settings, and connect to the E-Tube Project application to customize your shifting preferences. Bluetooth and ANT+ enabled, the MT800 system display wirelessly connects to smart devices and cycling computers for seamless operation and control anywhere you go.
