That really doesn't do me much good. You see, I originally purchased a TomTom with lifetime maps and that code is assigned to my account with the email address in my TomTom Home. When that defective unit was returned, TomTom (for some reason they won't explain) sent me a XXL 540 S back instead of the lifetime maps model. I was told that wasn't an issue as long as I USED THE SAME EMAIL ADDRESS AS THE ORIGINAL DEVICE. Well, device 2 they sent me didn't work either, so they sent me a third one. Guess what? That one doesn't work either (see my original post above on the scrolling problem, which is much more important here than my email address). So, now I can't return the device to the retailer because TomTom chose to send me a different model to replace the original defective one and the retailer won't accept it. And, I can't get the third one to work. I am stuck. Can't return it to the store and can't get this to work. Seriously, I have never seen such a lousy product. All I want is for this to work and I have spent hours of my time over the three different defective units to try to get it to work. If anyone at TomTom is reading this, just contact me to arrange payment for my original expense so we can be done with this whole mess because sending this back for a fourth device is really not something I want to pursue.
