I was wandering if I can combine two maps - one from the mapsource (currentlu - gmasupp.img) and one .img file wich I wolud unlock and make a .unl file. I thought that I could rename my custom mapsource map to gmapprom, and add new gmasupp.img map to my card. The thing is I need Auto drive Hellas, and there is no mapsource version, so I have to do this. Will this work, and will this combination be fully routable. My current maps i made of City Navigator Europe 2009 NT, Adria Route 2.20, SCG route 1.8, Navi Guide Hungary 5.0., ROAD 2006, Maps of Slovakia, Turkey, Bulgaria and Ukraine, and Roads of Russia 4.03.
Sorry for my English
