Hello All, I'm wanting to use copies of the same map on the same device with each containing a different .typ file, so I can switch quickly between one or another to have the map elements displayed with different colours etc.. Just putting 2 separate maps with different .typ files on the device (276CX) doesn't work as it only recognises and shows one of them. I imagine something that identifies each map has to be changed so the device thinks it's looking at two different maps. What is it that has to be changed? Thanks
