I have the same Cateye and moved it to another bike when I got a Garmin 500. The Cateye worked flawlessly for a year until I moved it to the other bike. Have had difficulty connecting, replaced both batteries, and it continues to lose connection and repeatedly have to go thru the whole setup process. If I didn't have the Garmin 500 I think I'd go back to the wired computer to save on the frustration and the cost of batteries. OP, I'm sorry that I can't offer any support other than the Garmin works great
