I just bought a TomTom One IQ Routes (Canada 310 N14644) and I was so stupid that I already broke my device. I whiped some of the files on the internal memory (the map I think) and now I get a notification that no maps are there on my TT. I downloaded TT Home but there I have to pay for the maps that I got free when I bought it!
