Summary: For all the bells and whistles that come with this Garmin it has 2 big flaws. First is that it has no Bluetooth so you cannot automatically sync your rides with strava. You need to connect the computer to your phone with cables and transfer the file using stravas desktop app.
Summary: Expensive piece of junk. Sometimes works. I had to have the unit replaced twice under warranty. You can buy this unit for $200 now although I dont think it is worth that. I am going to bin mine and look for something else.
Cons: Charger USB unit cooked 2 before I realised where the problem was. Have never had successful outing with this. Difficult to use. Battery goes flat on a ride after charging to 100%. Forget it for an all dayer. Not intuitive menu system.
the speedometer started to do the same problem like the first one
3 February 2015
Summary: Bought this before Christmas and was only using it for a couple of rides and the speedometer started acting up. Initially, I thought it was caused by the overcast condition that is why it was not giving me my accurate speed. Hence my average speed was all wacked after my ride.
Summary: This is a piece of expensive crap. I don't reckon I have finished a single session without something going wrong. Initially it was not downloading accurately, changjng dates and times. Then it was difficult to power up. Then it would stop recording certain functions.
Summary: This Garmin fails in all area for which it was purchased. It lost data on 3 of 4 rides, will not measure cadence or heart rate accurately, and rarely displays useful info. I am trying to return it, but because I purchased it during the winter and only recent put it to use, it seems Amazon will not...
Summary: Great product and functions but the HR readings become unreliable after ~6 weeks. Once the funny readings start, it will not work right on all subsequent rides. Indicates my HR at 8 bpm when it should be ~130. Then it gives good reading, then shows 40 bpm erratic. First unit....
Summary: I've had this Garmin 500 for 9 months. The first few rides were trouble free except the display is so small I can't read what's happening. The only function that works consistantly is pedal cadence. Quite often the speed dissappears and will later in the ride reappear.
Summary: I bought the GARMIN 500 thinking I'd have an all-encompassing, simple to use data collector for my bicycle workouts. Something I could easily track and review workout data -- mileage, speed, distance, cadence, & heart rate.
Excerpt: Old fashion mounted one that counts wheel turns and a HR rate watch.
Pros: works great on the road. Clock and timer work well.
Cons: Doesn't work in the forest. Always about 20% off the distance. can't figure out how (if even possible) to display HR as opposed to calories. When downloading to the web doesn't auto delete so over time, gets super slow
