A TomTom product owner can open a MyTomTom account online to activate a TomTom device, download the MyTomTom support application that provides software and other updates and request TomTom updates and notices via e-mail. You can also add contact details and make changes to your login information. TomTom provides two account access points -- a drop-down login screen on the TomTom home page and the MyTomTom main access page. Whichever point you choose is simply a matter of personal preference. Both access points request the same login information.
Go to the TomTom home page at tomtom.com.
Click the green "MyTomTom" tab near the top right corner of the page to open a drop-down login screen.
Enter your e-mail address and password in the fields and then click the "Log in" button to log into your account. If you want to stay logged in after leaving the site, check the "Keep me logged in" box before clicking the "Log in" button.
