@Simone-Marchi As if the above wasn’t long enough, do you have the following slow response issue with the SSU?
The route/map screen is way too slow to stabilise on raising wrist to view. I don’t know whether it’s the accelerometer, compass or GPS squabbling, or screen drawing speed but, when wanting a quick orientation reference, I find myself waiting for my Spartan’s route screen to stabilise, find North, doubt itself, move my location 50m, reset its aspect, move me again and demand compass recalibration.
