The way the line appears in the final gmapsupp.img is controlled by  
mkgmap's style rules.  Different OSM tags are assigned different  
Garmin line types by the style rules.  So you can control how your  
tracks appear by selecting the specific Garmin line type that is  
assigned to them.  If you want to go beyond this and use a custom  
style* for your lines you will need to delve into the dark art of TYP  
files.

* i.e. one that isn't a Garmin default for your particular GPSr
