I'm still waiting for a response from Garmin DE service if they will fix the gradient and the temperautra display. I HAVE BEEN ANSWERED ONCE with a generic answer of restarting your device. I am still waiting for a decent answer commensurate with the money I have spent on this faulty device.
Same problem with gradient in edge 830. It has got about 15/20 seconds lag.The function of displaying the room temperature is also disappointing, about 2/4 Celsius degrees higher than real temperautre.
I prefer to return this device and buy an older one that works well. Does anyone know of an older model that does not have these faults?
I think that all the failures are due to the change of the GPS chip for the Sony chip that consumes less battery but is less precise
