I ride before sunrise and use the "Always-On" backlight setting in the "System" menu. Battery life seems to take a big hit though. I was down to 1/4th battery after only a 2 hour ride. Don't need much backlight to see in the dark, would be nice if it were less bright to conserve battery.
I'm having trouble seeing the screen in bright sunlight. Wondered if there is a contrast or brightness setting
