Hi Harv, don't know about this particular model, but ANT+ sticks are cheap on
ebay, don't forget the USB extension lead too as the signal can drop off rapidly unless, the dongle is positioned right next to the bike. I know for my model, I need to pair via ANT. Bluetooth doesn't work as well, despite claimed functionality. I think you need a complete suite of bluetooth 4.0 devices as a minimum. ANT+ doesn't have such compatibility issues. The Zwift forum will no doubt have people asking this very same question, try there.
