That doesn't seem to be the logical route!! If you tell the navigator (Streetpilot i3) to reconsider whilst still approaching the roundabout, it will instead take you *north* on Ewenny Road into southern Bridgend then out again to rejoin the A48 to the east. If you enter this roundabout from the west on the A48 primary route and your navigator is taking you eastwards, then you'll be sent south on the B4265 for a couple of km, then east on another 'B' road to rejoin the A48 about 5km east of the rogue roundabout. I don't think it splits nodes with two exits, however. There's an option -frig-roundabouts in current SVN that does something to roundabouts to improve routing. I think editing the data would be the way to go - not necessarily in OSM if that wouldn't reflect reality any better, but as a preprocessing step when generating the routing graph. A workaround is to edit the roundabout in OSM so that the entry and exit don't meet the roundabout at the same node. Not sure what happens if it was bidirectional. This is certainly true if the afore-mentioned entry to the roundabout is a 'no candidate' for exit counting (like it's one-way onto the roundabout). Basically, if you have an exit on a roundabout which shares its start-node with the end-node of an entry to that roundabout, then the exit won't get counted. This might be mkgmap, or it might be in the Garmin StreetPilot i3 route-finder firmware.

Also tested in demo mode one route with same map but source being. osm: 3 routes that previously had problems didn't show problems.

Tested with Garmin eTrex Legend HCx in demo mode map compiled from.
