So I have noticed that there are some roads that Garmin thinks are still there, but they are dead-end streets. I have been adding these as avoidances as I discover them, however, basecamp will still route through them. Many times it is not even the best route. It is a little annoying because I am still learning my way around my area of work (I am an inspector so I drive a different route daily) so I don't know every dead-end and though I try to make a mental note of them if I haven't driven that particular route in a while or only a few times I tend to forget. Is there a better way?
