I don't use my Garmin 305 any more. I went with a Cateye wireless and like it much better. For one thing my bike looks much better without it. It's huge and literally is 2/3rds the size of my blackberry. You have to remember to constantly charge it as well. I used to use the cadence function but now I know what my cadence is by feel and can predict almost exactly what the display will show.
