In the past few days, I have received a warning message saying my Edge 1030 would begin deleting my oldest activities "soon".
This morning, it's raining, so I plugged my Edge 1030 into my PC and looked at my activities. This is a replacement unit due to the blue halo problem, so it has only 76 activities. I ride with Garmin Vector pedals and have cycling dynamics turned on, so my activity files are on the large side, running to 600KB in some cases. Anyway, I deleted all of last year's rides, leaving me with 16 activities on the Edge. Then I looked at Properties, and I have over 6GB free space.
I know that in the past, I have stored almost 300 rides on my Edge 1000.
Does anyone know the purpose of this warning message? Would the Edge actually have deleted rides?
