I recently returned my new GO 52 (VIA 53,) and replaced it with a GO 520 which looks like it's step in the right direction. The problem now is that I have both units in my TomTom Connect account. I've spent much time going through menus, forums, questions, etc. and cannot find any information on how to delete the returned unit. I even checked the questions section of this forum and only found how to change the email and log in information. Really would like to know why they have to make this sort of thing so difficult! Thanks for any help.
