Down Load time on Garmin 276c ( 512mb card) exceeds 24 hours

Two of us have Garmin 276c’s and have used this mapping successfully before - now we are both getting huge load times for the maps - mostly never loading. Initial load time will indicate 7 hours for the regular routable maps ( 475 mb for 522 card). Then it will rise to 30 hours or more…and simply never load…any ideas…want to go riding!

I’m not sure where/what your problem is. Where do you see this ‘load indication’? On the GPS or is the browser indicating the duration of the map download?
