On my Edge 200, I used a breadcrumb trail to Clevedon the other day, it was rather useful for unfamiliar sections of the route. I've got the 100km Tasty Cheddar Audax route saved onto it for when I have a bit of spare time...
I connect it up to my home PC every week to upload rides and charge the battery. I have it syncing with Strava. All in all for the money it's rather good.
The only thing is I would like it to display the current time when I'm riding along. Can't find out how to achieve that.
