Just purchased this unit from the LBS yesterday.

After hours of fiddeling, a few re-adjustments, and replacing $15.00 worth of batteries (The batteries are $5 each!) I'm still having problems getting any readings to show up on the unit at all.

I've installed the speed sensor on both the front and rear wheels, with no difference.

I've tilted the sensors (both the cadence and speed sensors) as close to the magnets as possible, without them hitting, and there's nothing showing up on the display.

Both of the senders have little gray buttons. The cadence sensor has a light that blinks when you push the button, and the speed sensor has no light. I'm assuming that these are either a reset or a connection button, but the manual makes no mention of them, or how to use them.

Does anyone have any experience with any of the wireless serfas kits? Or any other similar wireless kits, and know what i have to do to get these to mate up with the display? I don't think it's a problem with the distance between the sensors and the magents, because i've moved the sensors as close as possible, and still nothing showed up. And all 3 batteries have been replaced, so it's not a power issue.

Finally figured it out.

Battery in the speed sensor was loose.

Still don't have the cadence sensor to work, but it's because i can't find any way to get the magnet close enough to the sensor! The pedals on my cadent bow outward, so in order to get the sensor close enough to the magnet, the pedal hits it.
