Im evaluating a Coros Dura GPS unit currently, got it on sale 2 weeks ago, claims it has 120 hours of run time plus whatever the solar adds. Thats easily a week or more on tour. Can download RWGPS routes. Some funky setup quirks that I finally got squared away. The screen is not as big as a Garmin 1050, not sure it matters. Does turn by turn. Seems like a well thought out unit for a lot less than a Garmin. Will see how it goes.
