Actually, http://garmin.openstreetmap.nl/ is what I used first. The second link in my post is incorrect. These were the maps with the routing issues, but that was over two years ago, so things may have improved. I downloaded maps from my first link a bit over a year ago and these are the ones that "navigate" about twice as fast as CN maps. I have CN maps which work well, so no plan to further experiment with OS maps at this time.
