Sync BlueTooth to TomTom

Question

I'm trying to sync my Motorola Razr3 and Bluetooth to my TomTom One XL*S following the steps that I obtained from your website. When I got to the step which asked for a username and password, I came to a sudden halt. On the bottom left corner someone else's username came up. I emailed this person and he did not know how his username got on the TomTom as he had only used it once but had charged it from his computer. Do I have to purchase any services to sync my mobile phone to my TomTom?
