The question is: I know that I will have to erase CN from the Nuvi. But, should I erase just the .img file or the .unl and .sum too?
Thank you,

You could have one map in device and one map on card, no need to erase one in device if regions are not the same (no overlapping), so you can leave CN in device and compile other maps and put them in card, but if you intend to have one complete compilation on card then erase only gmapprom.img (gmapsupp.img) and appropriate .unl file, leave all other files on device. Put new .unl file (if needed) on card together with .img
