The XXL 540TM World Traveler Edition adds maps of Europe
Despite the higher product number, the XXL 550TM gives up quite a few options with its simplified interface, but still gives you lifetime maps and traffic in a 5″ package
The TomTom XXL 540M is identical to the XXL 540TM, except it leaves off the lifetime traffic
Meanwhile, you’ll give up both lifetime map updates and traffic with the TomTom XXL 540-S
Or keep the lifetime maps and traffic and give up a bit of screen size with the 4.3″ TomTom XL 340TM
