I'm new to all this updating of tomtom's. Decided it was time to update as it had been a while since my mate updated my tomtom and I thought i'd have ago myself.
Anyway after doing a lot of searching I finally managed to update my tomtom and get it working on these
Uk and Ireland maps 870 3419
The tomtom seems to work ok but the show lane image symbol in preferences is greyed out and not selectable.
On my old maps and navcore this worked so i'm not sure what to do to get this working again as I found it very useful
I'm not sure I have the correct navcore for a tomtom one v3 so if anyone could help me out where i'm going wrong I would be very greatful. Thanks
