I recently bought Bicimapas 2009 for my Garmin 60cx. When I loaded some of them, they wiped out my N.America map. Then, when I reloaded my N.America map, it wiped out Bicimapas. I got a notice of a free upgrade because I bought 2009 so recently. I downloaded it last night and tentatively it appears that I can load the Bicimapa and it leaves the N. America map intact.
