I agree, the maps are useful when looking for an address in the older (over 10-15 year older) areas of most cities. Calgary is a joke, they've been building new roads everywhere and redesigning interchanges all over the place. I used to like the gps when figuring what lane to be in to catch a certain exit, but now it will just as likely run you into some poor dudes backyard. I'd like to see car gps systems linked to Google with a voice interface, now that would be handy and a heck of a lot more accurate.
