That's not strictly true. I had lunch the other day with someone from RIM, and he showed me a 7105 talking via bluetooth to a GPS device.
It was being used for a corporate 'tracking' application, but having got the BB and the GPS talking via BT it wouldn't take that much more, surely, to add in navigation. Especially given BB's neat way of just sending little chunks of data. The whole thing could be 'hosted', just sending maps and routing into as needed. It could be really neat!
