Garmin released today Firmware Update V2.6 for the NEO 2T which enabled Zwift Virtual Shifting. Just need to update the firmware in your NEO 2T and you are done. Also, it works with your regular Shimano cassette so no need to purchase the Zwift Cog. There is also a firmware for the 3M which also enables Zwift Virtual Shifting.
