Appreciate a bit of advice for an old guy. I have had Mapsource on my computer for a number of years & have always easily been able to transfer specific map areas to my older CSX 60 or map 62 . Last year I downloaded Basecamp , but am unsure if or HOW I can transfer specific map arrears to these same GPS's. Under Mapsource I could use the tool in the tsk bar to highlight the arrears I wanted to transfer but I can't seem to find the tool in the Basecamp. I'm sure there a simple answer but don't want to mess up my GPS's. Any help / advice would be great. Thanks
