Good day,
The "Garmin Express" tells me each and every time I need to update my maps. Another hour wasted downloading and installing maps to Garmin 1000.
I am sorry for the troubles. There is a known issue with Express continually offering the Routable CycleMap 2015 update to the Edge 1000 devices. If you have completed the update please ignore the messages to update it again. The Garmin Express team is aware of the issue and it should be resolved in a future version of Express.
