I think you have found a little bug in the the data given to us by our data suppliers Tele Atlas.
If you type in:
201 N 300 W, UT or 201 North 300 West, UT then it finds all similar addresses in UT, of which there are 41, but nothing for Morgan.
If you type in:
201 North 300 West, 84050 or 201 N 300 W, 84050 (which is the zip code I got from Google)
then it does not find anything
If you type in:
201 Field Street, 84050 or 201 Field Street, Morgan (which is the local name for the road according to Google) RouteBuddy finds it because the Tele Atlas database is storing it as that even though the map data shows it as N 300 W
However, when RouteBuddy finds it, the address waypoint is placed on the corner of W 100 N as opposed to W 200 N.
I think this is a bit of an unlucky one, the principle with finding addresses in RouteBuddy is that all you should need is the number, street name and town or, preferably, zip code but sometimes, as is shown here, the Tele Atlas data that it is derived from is incorrect.
My house has been built for over 5 years now and still it is not on the latest Tele Atlas data! Unfortunately we do not have the resource to update the data from customer reports as Google do, i.e. they will take the raw data as supplied from any number of data suppliers which they use, and update it from customer feedback.
