Hello,

I have spotted a routing issue with a mkgmap generated map. I was able to reproduce it in several versions: 1188, 1228 and 1265.

The source file is the Cloudmade Michigan file (Sep 30), that I split using splitter. I can reproduce the issue either using the whole Michigan state (5 tiles) or just the tile where it happens. The tile were it happens has the following bounding box: 44.472656,-87.890625 to 47.548828,-83.144531

You can look at the following map: http://maps.cloudmade.com/?layers=&lat=46.115967&lng=-85.494747&zoom=13&directions=46.10180436619509,-85.43312072753906,46.093709975718674,-85.46968460083008,46.10025700105707,-85.49903869628906,46.14392361740517,-85.50504684448242&travel=car&styleId=1

If I try to route from A to B, either on MapSource or on my etrex Vista, I get a line from A to D and a line from D to C
If I try to route from A to C (or west of C), MapSource shows an error and the GPS can route but stille displays A-D-B lines.
If you try either route (A to B or A to C) in Cloudmade, they work fine.

I can provide the osm data (22 Mb gzipped) if needed.

Thanks,

N.
