My tomtom only gives Guam locations

Your problem might be that the GPS can't get a lock on the satellites and it doesn't know in which part of the world it is.

I suggest you download the latest updates and QuickFix, then leave the unti close to a windows (even if you are indoors). The unit should be able to getn afix on the GPS satellites in less than 15 minutes.

Please, let me know if you need more detailed instructions.

Tom Tom only has Guam map since update

That is really strange!
I can only suggest that you verify what MAPs are physically on your TomTom device by connecting it to a PC/LAPTOP and use Windows Explorer to look at your GPS drive folders: should see a folder for each 'country' (like GUAM).
The normal way to check which maps are registred and loaded on your device is to use TomTom Home -> Update maps function: it will show you the status or whereabout of any Maps that you have loaded or backup and which one can be purchased.
Hope it helps: let me know how you go.
ps.i f you wisely backup your device on a regular basis (via TomTom Home or direct copy to your PC/LAPTOP), you could always RESTORE FROM BACKUP and start again.

Setting country on tomtom one

This TomTom comes loaded with 2 maps....Guam and the US with Canada. I too got stuck in Guam and it is not obvious how to get out of it. But here it is.
Go to Main Menu, then Change Preferences
Hit forward arrow twice
Go to Manage Maps
Hit forward arrow once and choose Switch Map
It should show you Guam and the US and Canada
Tap US and Canada and it should take you out of Guam!!
Mine did and I am now going to delete the Guam map.

Try clicking on the main part of the screen during navigation. Then click on the "wrench" icon (Change preferences). Then click the blue arrow (2x) until you get to the 3rd page (Preferences 3 of 5). Click on Manage maps. Then click on Switch map. Then select USA & Canada.
