Hi, I am new here, although I have been a TT user for about 2 years. My problem started when my xl340m-live froze after an update. TT support had me send in the 340m and they sent a 340s as a replacement, saying that as long as I had the 340m with lifetime maps on my account, that I could sync the 340s into the account When I tried to sync the unit it kicked out an error saying that they could not be synced. Any help would be appreciated as I feel that I have been screwed over. Thanks in advance, Rick
