SOURCE: TomTom GO 720 - flashing red circle with white cross on screen
Hi, I am back, just got the problem solved, I called their tech support at no charge (866-486-6866, Glen) , really good service.
First turn your firewall off (if you have one). You need to go into your 720 with the TomTom Home software and erase the downloaded software (with the remove items from my device) and reset the device (little reset button under the unit keep it pressed for 5 seconds), place it back in the cradle and restart your computer and than restart the 720 , bring the TomTom Home program up, and when the TomTom Home software in your computer restarts and detects the 720 it will tell you that you need to update the application, if it doesn't than you force the update by going to the add maps option, select items on my computer, select applications and press the add button, when done, go back and to device (option in top of your screen) and select disconnect device, restart your 720 and it should be back to life with the upgraded software.
Hope this helps
Aldo

Same here today. Had to replace all the files with those I copied and burnt to a backup CD when I first connected the ONE. If I try just a map update through Home (not an application update) then I get a "No Maps" message after startup. I'll bet dozens of perfectly good units are being replaced by retailers everywhere. I am now going to seek an explanation from TomTom. It may just be that the current updates are buggy or corrupted. At least I had the sense to back everything up before I tried to update the thing so I can quickly get going again. Spent about three hours so far faffing about with this "plug and play with yourself" little marvel. Bah!

Hi - have had the same problem - if you look on the tomtom website and support they have a list and one is flashing red cross. You need to follow the steps to format the tomtom. I did this and it worked and it included the update. i havent reconnected since i have it working now. I think its a software problem with HOME. Make sure you do a back up on home and make sure you follow step by step. close HOME before you start to reformat and also in the preferences turn off the automatically connect to home when you plug into your computer or it keeps flashing up on the screen to correct. the only solution is to format it. i bought mine two days ago and the first one stuffed up so took it back for a replacement. this one worked when i turned it on but turned out the flashing cross appeared when connected to computer (i have a mac). good luck
