I did my test and I have two questions for you !
1: When I zoom in with MapSource, I can see all the restaurants, gas station and points of interest around where I live, but many don't exist anymore or has change name, not on this update ???
2: I live near a big city (Montreal, Canada) and many streets has been change to one way street or closed for pedestrian, not accessible by car anymore, not on this update ??
My Garmin told me to turn on a closed street or on the wrong way of a street ???
If I do the same test with Google Map on my cellphone, not a problem !!!
