While driving a while ago, I noticed highway ramps missing from my Vista HCx. Now, they are present but dashed lines. The problem is a combination of two things: a road that should be a motorway tagged as secondary (state highway), and mkgmap's default style not having rules for secondary_link and tertiary_link.
I built maps with the following patch, and in RoadTrip the ramps now
show up as ramps. Note that I used 0x09 insetad of 0x08 since that
seems to be the lesser ramp class.
