Something for you guys to ponder is that both of these units use usb to charge, they most likely arnt big power hogs, that said from the Mio's manual it takes 5v DC source to charge, why not just attach a solar panel to your bike? i mean you can buy one for cheap or make one for cheaper. I would suggest making one since you could use a flexible one and just wrap it around the frame bar. then you have unlimited gps for 16 hour rides if you wanted full with music, backlighting for night and what have you.
Why not wrap the solar panel around your helmet? That way it will protect you from space aliens as well as charging your GPS.
Note that the MIO is a very different product from the Garmin Edge. MIO has no route recording capability, so you cannot use it for training like with the Edge. How accurate is the speedometer? I doubt it has any odometer or altimeter capabilities. Of course, there is no heart monitor.
Can you create turn-by-turn routes on the MIO or does it force you to follow its route?
