Well I have never seen such a setting where you can exclude roads by 
type from routing. 0x01-0x13 is routable, and then with limitation 0x1a 
and 0x1b so how the fuck are you excluding a road type?
The GPS does not know whether 0x07 is a motorway or a residential road.* 
I don't say it does not work, I say excluding by road type does not exist!*

Some GPS and Garmin Mobile XT have the possiblity to avoid: Major Roads, 
Medium Roads and Minor Roads I have not found out what is behind these 
settings. I do assume: Major roads avois road_class 3+4, Minor Roads 
avoids road_class=0, and Medoi, Rpads avoids road_class =1+2
But never really tried this out.
