Garmin Edge 1030 and Di2 Connection I just got a Garmin Edge 1030, and have newer Ultegra Di2 with the buttons on the hoods. I was excited to see that the Garmin can connect to Di2. When I look for it in the sensors, it is not coming up. Do I need to add an ANT+ transmitter to my current Di2 setup? I am not sure, or is that something that should already be installed and the problem is else where?
You need to install a D-Fly unit. Probably this one:  EW-WU111
Being able to use the Garmin in rain and cold weather with gloves is brilliant.
However check if you have the right components: these batteries are ok: BT-DN110 / BM-DN100
