I just recently purchased a garmin gpsmap 60cx. Love the features and how easy it is to use. Also purchased a microsd card(topo map) for my area in Canada. When I connect my unit to my pc(installed the waypoint manager cd that came with the unit) and I click the receive from unit icon it gives me an error saying that some maps won't open without topo canada v4(this program is 5 GB). I would like to be able to print and edit the same maps from my computer that I see on my gps? Is there another solution or do I have to download this large attachment? Thanks in advance.
