Update: this morning no light (yay.) Still no movement on calibration.
Mid-commute I received a firmware update notification, 220.127.116.11 I think. Pulled over, installed that and boom, GoFar was tracking the drive, Ray showing lots of nice blue light.
Sorry for the late reply, we've been looking into it.
Super glad to hear that the firmware update fixed the problem!
I hope you enjoy your GOFAR and please don't hesitate to get in touch if you need anything.
