Are they any good? Will i be able to upload to strava?

Whats “map” mode? Can i use it to navigate a route?

It’s small and compact with fairly programmable. You can’t navigate with one as you can’t upload .gpx files, map mode just shows a trail where yo have been. The most frustrating thing is up loading the ride, on a mac the softwares is shit, not sure if it’s any better on windows.

Thanks.
I can’t decide if I should be saving up for the 305 or getting a 100 now.

I’m not sure if I’d use the HR monitor and cadence but navigation could be handy.
