FWIW I just downloaded Gaia for my phone. Seems to be pretty reliable compared to previous phone GPS app. Maybe this will work after all. I will test this weekend either hiking or cycling or both.
Re GPS I'm wondering if a basic etrex 20 or 30 would be better for touring due to the use of AA batteries. Easy to pack spares. Then again, cheap rechargeable battery phone/device chargers are available these days, possibly making this sort of thinking obsolete.
I anyone using the 'cheap' Garmin GPS cycling computers, Edge 20 and Edge 25?
