I've just used Garmin Express to update the EU cycle map on my Garmin Touring to 2016.10. I also have Basecamp v4.6.2 installed on the PC, which is running Windows 10 x64. When I go into map options in Express after the update has completed, there is an "Install map to computer" option, so that it can be used with Basecamp, but the button to do this appears to be greyed out and does nothing when I click on it. How can I get this function to work? I've attached a screen dump of the Express window.
When I disconnect the Edge Touring and check the enabled EU maps on it, they are:
Garmin cycle map EU 2016.11
Edge DEM map EU 2014.20
Garmin Geocode map EU 2016.10
