Reading the message boards, I notice a couple of people have had the same problem I have had. I purchased a Timex speed and distance and few months-I had no problems (no signal loss, weak signal,etc). Recently, the I started getting lost signals almost all the time on the same route I run when it worked perfectly. I returned the watch for a new one and have had the same problem. I also bought the garmin forerunner and I think thats even worse. I noticed others have had the same problem of it first working and then not. I thought it might be leafy trees but it seems to happen in with no cover. Curious what people experiences are and how the solved them.

Which Forerunner did you get? I've been using the 201 up until a few weeks ago. I've had some issues with it, but that was almost always due to tree cover on trails. On the roads I had no problems. I recently started using the 305, which includes a heart rate monitor. The x05 series of forerunners use a SiRFstarIII chip set, so they acquire satellites faster and stay locked on better than the x01 series (even under tree canopy or "urban canyons"😉. It does seem odd to me that your device would work, but then suddenly stop working, even with 2 different types of technology. I'd call Garmin support and see if they have any ideas. I once had a problem with my 201. Garmin support was very quick to replace my device with a new one, since it was under their 6-month warranty. That's one reason I stayed with Garmin rather than Polar.
