Summary: I purchased this for the GPS feature so that I wouldn't get lost on country roads. When moving the road ahead disappears when moving, so the GPS feature provides no guidance to me. Basically I have to guess which way to turn and then use the "off course" message after the fact to see if I made the correct turn. To make matters worse, the "off course" message sometimes displays when the signal is weak, so sometimes I think that I made the wrong turn when I didn't.
Summary: This unit is wonderful; finds satellites fast, long battery life, nice screen configuration options. However, after only a dozen or so rides, the back tabs broke off and the unit went flying. I only use for road biking, and upon further investigation this seems to be a fairly common occurrence with this model. I'm not discouraging purchase, but rather extending a cautious warning to how you mount.
Summary: I ordered this thinking it would replace my Edge 305 with all the features of it and then some. I also called Garmin direct to confirm this. I just received my Edge 500 and cannot believe that the map is not useable unless you do a "course" ahead of time. For example you take off on your mountain bike to a unknown area and you want to get back to where you started from.
Summary: I'm a long-time 305 user, and I've been very happy with it. When looking for a new GPS unit, I figured the 500 was the next natural step, plus I get the ability to sync w/ power measuring products. The 500 is essentially billed as the fancy new upgrade to the 305, but ATMO, it lacks a significant feature that the 305 includes. This unit lacks the live route-tracing feature of the 305.
Summary: The device is great - when it works. Every time I go for a ride, I have to start it 30 - 45 minutes before I ride to make sure it has enough time to lock on to satellites. Most of the time, I am 7 miles into my ride before it locks on. If I take my bike to another location to start a ride, it takes longer. Very annoying. I live in So Cal and don't have trees or buildings in the way. And software updates don't help.
Summary: I purchased the Garmin Edge 500 about 3 months ago and was using it 4 or 5 days a week during my training rides. On weekends I would do longer rides and often I would download a course to follow. Well, quite often the unit would 'freeze' while following a course resulting in me having to do a master reset (press all 4 buttons at once) and also resulting in data loss for my ride.
Summary: Device is excellent, heart rate strap is great, comfortable and unobtrusive but the cadence detector unit will only pick up wheel speed. As I am now outside the returns window I have had to deal with garmin tech support. They give the impression that it is a common problem.
Summary: Le compteur est intéressant, mais la ceinture cardiaque (made in China) totalement nulle; La 1ère est tombée en panne au bout d'1 an et a pu être changée sous garantie, avec cependant 2 mois d'attente; la nouvelle ceinture vient à nouveau de tomber en rade au bout d'1 an; Dommage car ce compteur me parait intéressant, très complet dans ses fonctions avec un affichage paramétrable.
Summary: Wer einen leicht zu bedienenden und zuverlassigen Fahrradcomputer braucht ist mit dem Edge 500 gut bedient.Wer aber ab und zu mal selbst erstellte oder runtergeladene Strecken abfahren will,der sollte sich bei anderen Herstellern umsehen.Es funktioniert einfach nicht zuverlässig.Egal wie oder womit man die Strecke erstellt,immer wieder ist die Streckenanzeige weg.In unbekannten Gegenden sehr unangenehm.In diversen Foren(u.a. auch auf der Garmin-Internetseite!!!
