The process for converting OSM data into Garmin maps is entirely 
software-defined, so if you want to represent unpaved roads differently 
to paved roads that's entirely possible.  There's quite a bit of 
information of https://wiki.openstreetmap.org/wiki/Mkgmap , and there's 
other information elsewhere.  I wrote a diary entry 
https://www.openstreetmap.org/user/SomeoneElse/diary/38613 ages ago to 
deal with the reverse problem - someone modifying OSM data incorrectly 
so that it appears as they wanted it on their Garmin.

If someone wants to do the opposite (avoid unpaved roads by representing 
them as tracks) that's entirely possible too.
