Hi Greg,
my understanding is that Garmin treats 0x0c special to produce the "leave roundabout at the nth ..." hints, the same for 0x08 and 0x09 to produce the other exit hints. The calculation of the "nth" exit requires special logic, that's why roundabouts need a special type.

I noticed that I have one linetype (0x0c) for roundabouts and it had many different ROAD CLASS and ROAD SPEED # Roundabouts junction=roundabout & (highway=trunk | highway=trunk_link) [0x2a resolution 18 continue] junction=roundabout & (highway=trunk | highway=trunk_link) [0x0c road_class=3 road_speed=2 resolution 18] junction=roundabout & (highway=primary | highway=primary_link) [0x2d resolution 18 continue] junction=roundabout & (highway=primary | highway=primary_link) [0x0c road_class=3 road_speed=1 resolution 18] junction=roundabout & (highway=secondary | highway=secondary_link) [0x2e resolution 20 continue] junction=roundabout & (highway=secondary | highway=secondary_link) [0x0c road_class=2 road_speed=1 resolution 20] junction=roundabout & (highway=tertiary | highway=tertiary_link) [0x2f resolution 20 continue] junction=roundabout & (highway=tertiary | highway=tertiary_link) [0x0c road_class=1 road_speed=1 resolution 20] junction=roundabout & (highway=unclassified | highway=residential | highway=minor | highway=living_street) [0x25 resolution 22 continue] junction=roundabout & (highway=unclassified | highway=residential | highway=minor | highway=living_street) [0x0c road_class=1 road_speed=1 resolution 22] I also have 2 other linetypes for HIGH SPEED RAMPS (0x09) and LOW SPEED RAMPS (0x08): highway=motorway_link [0x09 road_class=4 road_speed=7 resolution 15] highway=trunk_link [0x09 road_class=4 road_speed=5 resolution 18] highway=primary_link [0x08 road_class=3 road_speed=1 resolution 18] highway=secondary_link [0x08 road_class=2 road_speed=1 resolution 19] MY QUESTION: Can I combine all of these different ROAD_CLASS and ROAD_SPEED together using 0x0c and free up 2 routable linetypes? Yes, all the map elements would like the same. Greg
