Garmin 830 Setup

I updated my bike computer from the dark ages, Cateye double wireless, to a Garmin 830 with all three sensors. What do I need to purchase to communicate to Zwift? I am using a Cycleops Fluid2 trainer and have an iphone/ipad.

You cannot use a Garmin 830 on Zwift.

If the sensors are Garmin than more than likely they are ANT+ only so you would need either the 4iii Viiiiva or CABLE to bridge the signal to the iOS device.

Is the Cycleops Fluid2 the Smart version?
