I'm in North America but planning to travel to Europe for a race. In Map Manager on the watch, I hit the 'add map' - it connects to Wifi, says 'Requesting Map Update Data' but then just buzzes and returns to the previous screen where it still only shows the North America map. I was expecting a list to choose from to download - do I need to be in the location to download that region or something? I may not have good wifi so was hoping to pre-download. I have updated to latest firmware 17.23
