Hi Steve, Well, that's a bit odd. If you download this area into JOSM, it looks similar(ish) but by no means exactly the same. If you then run that area through mkgmap and look at the result with mapsource, it looks OK. I am wondering if the map image in the email was made from out of date OSM data that contained the problems the image shows? Cheers, Mark -------------------
I'm am forwarding this email, with permission, in the hope that someone can help before I able to look at it at the weekend.

Hello Steve,
Marvellous piece of work, mkgmap! Incredible, really. Although, naturally, there are a few glitches and here's one of them.
It could be that there's glitches between the connections between two parts of a map (as I'd guess that the position is somewhere between two sub-maps), but I'm not 100% sure of that.
This http://tile.openstreetmap.nl/?zoom=17&lat=52.01375&lon=5.11781&layers=B00000... is the position on OSM, and this http://valentijn.sessink.nl/temp/CIMG7132.JPG is how it shows up on my Garmin Nüvi 250, while what I did follows shortly. Please note that I did not use "remove-short-arcs" before, I added it *because* there were a few of these unconnected roads in this region and I thought that --remove-short-arcs would fix that. Now I'm not so sure anymore ;-)
I'll be happy to test new options and I hope this will help to improve mkgmap (if not, please ignore ;-)
Best regards,
Valentijn Sessink
