I have downloaded the SE USA map for my tomtom for my holiday in a weeks time however can't seem to access it on my device (although the computer shows it is installed on there). Do I have to wait until I have landed in the US before it will display?? Thanks
sal_333's post is correct if you are wanting to swap over to alternate maps. Having said that you won't be able to route a trip etc... until you get the GPS to a location that is within the map coverage.
