I read a press release that Garmin will offer a navigation application for the BB8800. (Here's a link
.) When I first heard about this, I thought it would an excellent solution and I wouldn't have to shell out for a Nuvi. (I travel a lot.) Now I'm starting to wonder. Apparently the maps will be dynamically loaded. I can imagine that would cost a fortune in data charges and it would also be subject to the speed of the network, which means it might not work as reliably as a unit that has the maps stored internally. How well does the existing BBmaps work with a GPS? Am I worried about nothing?
