This was indeed tricky to install. I was just about to return the device until I tried something a little different from the so so instructions. I tried to pair same with my TGT first by selecting Scan under speed/cadence (after) installing it on the bike (this did not work). So I removed the sensor then tried again, scan successful (I noticed a third option (SPC) after the successful scan which is now utilized AUTOMATIC every time I turn the watch on. Back on the bike it went. At this point I was only receiving a cadence reading, no speed. The photo in the instructions show the speed sensor attached to the bottom of the rear fork (speed sensor pointing toward the ground with the battery access facing outward). THIS IS WRONG! I flipped the speed sensor around so that it pointed upward/battery access facing inward. It finally worked I got the speed! Also, I have the magnets nearing touching the sensors. 3/8" (10mm) was to far apart. When the battery dies just flip it over, replace and flip it back.
This is very easy to install, and I had no issues with the device connecting to my Timex Global Trainer. I put this on in less than 30 minutes (probably more like 15). The instructions were very easy to follow and the biggest issue you will have is probably getting your bike up high enough to work on it. There is a magnet that attaches to the crank arm. The teathered sensor attaches to rear trailing fork arm (opposite of the chain), and a magnet to the rear wheel spoke. You line up the magnets with the sensors and your done. You must turn on the sensor connection in your watch (device) to scan for the sensor, but my watch did this in less than a minute. I highly recommend if you using the Timex GPS collection and are using it for multi-sport applications.
