It depends on which map you use. I do not actually have any TT units, but use TT Home on maps using an SDCard. I get map updates on it. Certainly works on a GO720 (using a card). What you did not mention was the map and version of the map you use and it may not have any updates to load anyway. Quite often there is a pause from having new maps and being able to update mapshare. Europe certainly has updates available now.
