both are on the MASS memory, fr some strange reason they wouldnt work on the memory card slot!
with the tomom 6 i just copied all the files and folders (i think there are about 27 intotal) to mass memory and it worked without having to do anythink! i use the external nokia LD-3W with tomtom. the ONLY problem i have with tomtom now is its a bit tricky to input and address or postcode, seems a bit slower and fiddlier than it was on my n95 and n95 8gb, but once your out on the road using it, its fine!!
copilot live 7 work with internal gps reciever or external gps (at first i had trouble installing copilot but got help off this forum from another guy)
