I used this for the first time on saturday & thought it was quite the thing . There are a few things that drove me nuts & will have to figure out before I use it again:
You can't see your estimated time of arrival if you don't download a trail/route (Rather important for an Audax or Mtb event)
The screen keeps moving to a new page every few seconds

I also can't figure out why a trail we've downloaded from bikely & put on google earth won't upload (download?) to the Garmin.

I'm new to all this....

So far so good.
