GPS easier to use than cell phone which can have gaps in coverage.

What good is a GPS that loses turn-by-turn directions when you're 200km into a ride and you happen to get a little tired or you take a detour

I would much rather stay with a non-touch screen model and an older model with a much reliable GPS system

I think it's quite likely that my unit has a bad GPS

iPhone BT connectivity issues (GPS location on the iPhone jumps 1,000s of miles, while GPS on the 820 appears correct)I am a MTBer and bought this device to get accurate mileage, cadence, and ascent/descent data, and was compelled by some of the other features like incident detection, text and caller notifications.

Great GPS for cycling you can customize the Garmin as you like with the app store
