Sorry if already been answered. I have a via 130 sat nav (nav3) I have updated a few sat navs with TTactivator, but having trouble putting 1100 europe _camper maps on this one it loads 1095 truck maps and I can put 1100 uk-ireland maps on internal memory but can't get the latest europe _camper maps on it. I have installed the 1100 maps on 3 other sat navs
