Certainly on my devise (GPSMAP 62s), where a road having one of the 
standard default Garm,n routable codes makes a junction with a road 
having a custom 'extended' type code then the former 'pushes into the 
latter making the result rather unsightly.

I am wanting  to use one of the 'routable' standard codes to draw the 
roundabouts with an 'overlay'.  However, as I already have the 
roundabout code (0x0c) in invisible form on the same region of road I 
want the overlay to be non-routable otherwise there will be two routable 
lines in the same place in the same layer.
