I used the Edge 810 for the first time on 200k Audax, and the auto-shutdown feature is driving me mad. Charging from my dynamo hub cause the unit to start shutting down, whenever I stop. From what I can tell, there's no way to disable this?
I also took a usb power-pack, this was pretty unreliable too. I suspect some of the rougher terrain caused the device to stop charging. It wasn't reporting as 100% charged.
I've previously used an Edge 800, which was perfectly happy plugged in to the dynamo for most of my longer rides. Unfortunately, I charged it in the rain one too many times and the micro-USB port is corroded. The last ride I used it on the screen also fogged up too.
I've scoured ebay, but there's not much in the way of spares for the 800. Has anyone got an effective charging strategy for longer rides?
I'm tempted to ditch the Edge for an Etrex. I understand it the 30x can also record ANT+ speed/cadence and HRM sensor data?
