Can't find USA map on TomTom One XL

mdr55

Hi, I installed a map of the USA onto my TomTom One XL device about four years ago with the assistance of a memory card. It worked perfectly when we went to the States. But, now we are going back and I am not able find it on the device. When I go to manage my maps I only have Western Europe and I can't find the USA map anywhere. When I connect the device to my computer I can see that there is a USA map folder, but no way of accessing it on the actual device.

Connect the device to Home--Manage my Device--Items on Device-->maps, what does it say?

Items on computer-->maps, what does it show there?
