Well i am writing this wile I am trying this out...
I have a TomTom Go 910 that has a RED CROSS FLASHING on the bottom corner, what I have found is that if you have backed up your TomTom Go i maybe able to reset the TomTom Go on my computer but if you havent you may have to find on try finding one on google but i have a TomTom Go 910 you can download the 910 on http://rapiddigger.com/download/backup-go-910-rar-9110176/.

after you found the back-up you can connect your TomTom Go to your computer using the USB provided from your TomTom Go, replace the doggie file with the new one, then this should change it back to the FIRST update given...

(WARNING >> PLEASE scan the file befor you put it in your TomTom Go it might contain a very very evil virus<< WARNING)

Usually an X on the screen indicates that your GPS (navigation) software is no good (corrupted, etc.).
If TomTom support is not able / willing to help you to download and install the navigation software, you're likely out of luck. If you are able to re-install the navigation software (& map) and you are still getting the X on the screen (of your TomTom device), it may mean that the (storage) memory on the TomTom device is faulty. You can try to connect your GPS to your computer and see if you can "repair" the TomTom (storage) memory (disk). That would usually just block off the bad areas, so that it will not be used. Then try downloading and installing the software and the map again.

try re-setting the unit by the re-set botton on the back or side of the unit depending on the model

If your device only shows a cross after you turn it on, the TomTom application is not installed or cannot be found.
