How big of a problem is the lack of way points? Its simple enough to change the destination to the way point and then when you get there go back to the original destination. I love the fact that I can not only use a voice command to navigate to the destination, but the screen will show a pop up with info about the destination (e.g. if its a store, is it open or closed).
To me the bigger issue (and the problem with any phone based system including the one in the MY) is that it is not based on satellite GPS. I had a lovely experience when driving from Las Vegas to Saint George Utah and Google maps suggested an alternate route based on 15 minutes of construction delays. Unfortunately, I lost cell service and the Maps app didn't notify me when that happened. So I was driving along happy as only a clueless person could be. When I finally realized I was lost, and checked Google Maps said it couldn't find any way to Saint George from my current location. The car had an old style GPS and when I turned it on, it said I was 30 miles past the turnoff. I arrived at my hotel over an hour later than I would have without the help of Google Maps.
