Today after 02h44 into a ride (race), I noticed that my head unit froze. The touch screen was completely unresponsive.
After the race, I switched it off, by holding the power button. This at least worked.
Now, it refuses to boot up again. I have tried holding the power button until I hear a startup sound, but nothing displays. When "clicking" the power button, there is a sound but NOTHING on the screen. I have tried the suggested methods and key combinations to restore it, but to no avail. Is this a paper weight now?
PS: I was running a stepped workout function to estimate power requirements as per Best Bike Split functions. No ConnectIQ apps etc.
