Hmmm.. yeah. For the Canada CD, I just looked at the samples on gpscentral.ca and ordered it. Great disc.
For the Europe Streets, another BBSer is buying a copy on my behalf from Amazon, and then remailing it to me. I figure it'll be good enough for London, Cambridge, Amsterdam, Paris, and maybe bits of the German/Swiss alps if I'm lucky.
I already have the European basemap for my Magellan (those are downloadable from the web, with neutral non-acknowledgement (don't ask, don't tell) by Magellan.
