it detected the cadence sensor, but not the speed sensor. I tried everything to make it work, but no luck; even took the magnet and passed it by the sensor every way possible and still nothing. I called apple and they quickly raised a UPS return label and about 10 minutes later I got an email letting me know that a new one was comin my way. Hopefully this one works fine. Kudo to apple for their service, but not so much Wahoo for a lack of quality control.
I'm on my second unit with the same issue. Speed sensor will not work

I moved to this unit from my ANT device since the iPhone 5 bluetooth is pretty reliable for my fitness devices. I use the heart monitor and the Blue SC device from wahoo. I can get the cadence to work but the speed arm doesn't. I even removed the device and did the manual test by moving the magnet over the notched area on the arm using the wahoo utility but to no avail the speed doesn't record. I purchased a second unit to see if the first unit was bad, changed everything out but still the same results from all the test; cadence works fine but the speed arm doesn't. I will contact wahoo to see if my lot number is from a bad manufacturing batch. I've installed over 4 of these types of devices so I understand how to line everything up.
