Just go to the tomtom website (see below), and find the desired map (update) for your device.

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.

This problem is due to the memory card not containing the TomTom application or map. To update the application onto the memory card, Connect the device to your computer. Open the TomTom Home application. Click on 'Update My Device'. This should then install the application onto the SD card. Alternativly, you could perform all the steps above without the SD card in the device, this will install the application onto the internal memory. Note: you may also need to install your maps, voices, etc after you update.
