My friend just got the NA 7.15 map and I was comparing my 7.10 map with him. Didn't notice anything special other than most of the major highways and interstates have speed limit on them now. This actually fixes the problem of tomtom being way off on calculating the arrival time. I didn't get to play with it much to see if the routing is actually different or not, maybe somebody else can chime in. Is 100 bucks for the new map worth it for the feature that should have worked all along anyways
Here is the 710 map and below is 715. Notice that the speed limit is now shown on the bottom right and total time difference to destination.
