Is there a specific reason why the Edge 130 Plus is not compatible with the Shimano Di2 electronic shifters? Is it related to connectivity issues either via Bluetooth or Ant+? Is it a firmware issue because of the small screen size? Or is it a software limitation that can be overcome with an update at a later time. If neither of these, is is just a ploy by Garmin to make you buy a more expensive unit? Just curious. My new bike has these shifters, but with a 1X set up so I don’t really need the integration that badly, but it would be nice to be able to move screens with the shifter buttons.
