I don't know which model chest strap you have, however just checking the Wahoo website the latest Tickr and TickrX will both pair with up to 3 bluetooth so if you have either, you should have no problem. The TCD display is a little confusing, holding which button/buttons for how long, what you want on each of the 5 pages, but you can't ever get in a hole that you can't get out of. The set up as you know is on P. 14 of the user manual. If it would help I can walk you through the set up by PM, text, or phone.
