Anyone using a stealth 50 with a GCS-10? need help pairing
 

So I picked up a Stealth 50, which I really like. My Wahoo HR strap paired flawlessly with it and my phone via BT. I got a GCS-10 on fleabay in order to see cadence (and to have speed on the trainer) but for the life of me, I can't seem to get it to pair. I reset the 50 and proceed to the appropriate screen (i.e, cadence) and set it to sync. Then I hit the reset button on the speed/cadence sensor...but it refuses to do anything on the computers side. Is there some way I can find the devices ID number to input it directly into the computer? The Wahoo strap sync'ing displayed the ID number, which I recorded for any future needs. TIA.

I don't have one so I am not 100% sure, but I thought that needed the ISC-11 Speed/Cadence CatEye ANT+ Integrated Speed/Cadence Sensor for that unit not the Garmin GCS-10 which doesn't use ANT to communicate.
