Something like this happened to me mid-ride. Thought it was totally broken. Powered off for the rest of the ride, and when I restarted later came back OK
I just bought one and the same thing happened to me after one ride. Totally blank screen snd only the "back light" works. These devices are way too expensive for this crap to happen. I'm not happy. Not happy at all.
I just bought one and my did the exact same thing after only one ride. These devices are way too expensive for this crap to happen, and it sounds like it happens often, based on the replies. I'm not happy, not happy at all.
