I live in the 44147 zip code, and Broadview Road (Route 176) has sections that are no longer available to map a course on. If I try to route a course on that road, it sends me on a long detour, and sometime tries to route me to nearby, parallel roads, as if portions of Route 176 do not exist. This worked several months ago, and seemed to stop working more recently. There was a recent construction project on Route 176 that made it a one way street for a period of time. I am not sure if the construction project might somehow have disabled selecting Route 176 as a navigable course. Unfortunately for me, I live along Route 176, so I am unable to use that mapping if Route 176 is not recognized.
