Can anyone tell me the difference between the Garmin Edge models? For
instance - what is the difference between a 520 and a 530? I think that
one of mine is an 830 and it has a lot of buttons on it and is a
pain-in-the-butt to get working though the basic software appears to be
the same thing. There are several probably Chinese copies some of which
seem to have a better program and display as well as a longer battery
life. But they don't connect to a Garmin mount and the one's they provide
don't work for integrated bar/stem combos. The Garmins have absolutely
terrible screen contrast and most of the time wearing sunglasses I can
barely make out the speed leg alone the mileage. I will say that I really
like the rear wheel placement of the speed and cadence mechanism I can't
think of any possible worse position for a speed pickup that a front
wheel But I may be biased since that is partially how I got my concussion.


530-830 are the next generation and have fixed a lot of Garmin woes,
DCRainmaker is keen on both.

Main issue with the older Garmin’s was the processor was so slow, 520 plus
has a reputation for being dreadful for this.

A friend has a 530 which seems ok, I have a much older and slower Touring
which is quite feature rich for navigation but quite slow.
