Why is the GO 52 that I just bought brand new identified in my TomTom account as a VIA 53? Is that really a european model rebadged in the US as a GO 52? The name convensions that TomTom uses on their equipment is really confusing. You buy a unit labeled on way and then they call it something else. I'll admit that if you search for support for a GO 52 on TomTom's web site nothing comes up that's useful. I found that curious when I was searching for a copy of the owners manual but it didn't seem to exist. Any help deciphering this is appreciated.
