Re: Worldwide routable Garmin maps: URL REMOVED

I'm having trouble with routing in Basecamp after downloading a chunk of the 20130829 map. For example, between N44 20.444 W72 38.644 and N44 20.454 W72 38.669 on South Bear Swamp Road in Middlesex, VT, USA, Basecamp acts like the road is non-contiguous and attempting to route from the south to the north results in a U-turn, heading back south, and then looping in from the north. I don't see a break in the data via openstreetmap.org. I'm having similar issues on Bushey Road between N44 20.477 W72 37.735 and N44 20.355 W72 37.793 (OSM link) as well as on Molly Supple Hill Rd (just east of Bushey Rd) and French Rd (which intersects Molly Supple).

Is this a glitch in the OSM -> Garmin map generation process or is it a Basecamp error?
