I have just installed BC 4.0.2 on my PC (Win7-64) and have connected my Oregon 550T. When I select the map from the dropdown from my Oregon (it shows up as "WW Autoroute DEM Basemap NR") all I get is a sketchy map with only major roads and railways. Zooming in doesn't even show the roads in major city. I believe that this is a limited map stored on internal memory in the Oregon. I also have a memory card in the Oregon which has detailed map of the province of Ontario. Can I display that in BC somehow?
