This is the same route with "Avoid u turns" NOT set on. Much better, but, apparently the maps do not show the left turn available into this small shopping mall. Garmin wants me to make a U turn where a left turn is available - you can just see the magenta line going beyond the flag.
So
luvlabs I think you're correct about the map data. This is a divided street with occasional left turns. I set it for 'avoid u turns' when towing, but it that may cause G to take circuitous routes.
And
AprilWhine was on the right track also.
