The sensor is also a backup to the GPS for speed (it is wireless). Meaning the unit first looks to the GPS, but if the signal is bad (tree cover, tunnels, etc.) it will use the sensor as a backup. You can manualy input the tire size, or set it to automatically compute tire size. Thats what I do.
Also, it is a good idea to turn the unit on after charging and then turn it off again. If you don't sometimes it will discharge the battery; I'm not sure why, but this seems to help. The mode/lap button trick is good to remember. Or you can hold mode, lap and power at the same time. Sometimes one way seems to work while the other doesn't.
Lastly, when you put the unit on the mount, make sure it clicks and then give it a little push to make sure it's on securely. People complain about it coming off during a ride, but I've had mine since '07 and never had a problem (and while I don't mountain bike, I've been on some pretty rough roads).
I do like mine. I don't have a power hub & have no need for maps, so it does pretty much everything I want it to do. For the current prices, it's a great deal unless you specifically need some of the features found on the more expensive units.
