I'm trying to get my arms around GPS options without having to spend a ton of money and have a very specific use case (though certainly not very unusual). I would like a unit that allows me to upload a route/cue sheet and spit back instructions on where to turn while showing me my location on a map, preferably with an audible cue (could be a ping, not necessarily "turn right in 100 ft").
Handlebar mountable (either out of the box or with a 3rd party mount)
Reasonably water resistant so I don't need to baby it.
Under $300 (or so)
Rechargeable batteries with a 15 hr+ run time (if possible)
What I don't need (though it's okay if it's there):
Track generation and storage
Speed, cadence, heart rate, etc.
Used/discontinued is okay but I'm cognizant of map update costs. Primary use will be lightweight, long distance touring and rando type activities. Thanks for your opinions!
