Hi Alexis, so far there was no need to handle these relations in mkgmap, so I am pretty sure that it doesn't work well. What important information is in https://www.openstreetmap.org/relation/11999802 that is not also in the children?

I may have misunderstood something for the relations I would like in my case to carry over the osmc:ref tag to the child relations. https://www.openstreetmap.org/relation/11999802 Thank you in advance for your help. ---- Alexis LECANU https://www.facebook.com/Garmin-Connect-App-Alexis-Lecanu-395326794312827 If you want to pay me a beer to thank me: https://paypal.me/alecanu
