Marvin, Street Atlas is lovely in lot of ways, but forget it for the 401! I'm planning a trip to Utah again, and this time I am using S&T and Street Atlas to plan, and an ASUS R300 PND [runs IGO] in the car as well. Street Atlas screws up royally at Yonge Street going east from the 401 to north on Yonge, exiting at Bathurst Street from the 401 westbound [that one is a real classic... you'd drop 20 plus feet into the park if you tried to get off the way they show, and for going from the 401 westbound to the 403 to get down to the QEW at the Ford Plant in Oakville. I've complained about all three since they started to cover Canada and they still don't have these exits correct. Since I know the truth about the 401 after all these years, I just don't pay attention to what Street Atlas produces as far as that is convered. I really need it from the duty free at Fort Erie on to Pittsburgh, and then west to Pikes Peak, Moab, Ogden and back until I get to Sarnia. Then I do NOT need any program <grin> since I've driven them a few times already. Basically I only use the lagtop to prepare for the trip, look up addresses, and so on... and then will use the ASUS R300 for the rest. Love that little GPS and it has a replaceable Lithium Ion battery too,. plus an FM transmitter, etc. The larger version is more than I need or my wife would put up with <grin> as she definitely considers it a toy!
But it too has problems. I just decided to plan a trip from Yonge and Elmhurst to the Mandarin at 1027 Finch Avenue West, and the ASUS takes me to the traffic light past the Mandarin to make a U turn to come back to the lot where the Mandarin is located. They seem to think that Finch has a concrete separator there... WRONG...
Oh well... and keep on GPS ing...
