The TomTom 410 is not exactly the same product as the 450. The 450 is the successor of the 410 with a better integrated display. But the real difference between the two is that the 410 comes with an extra dual charger. But if you don't need that, I recommend you to buy the 450. I have read that there are quite a few problems with the display of the 410.

The world maps must be installed separately, but free of charge. However, it is necessary to use a microSD card. All maps are standard and for all vehicles. You can find more information on this subject at the following link: https://fr.support.tomtom.com/app/content/id/8/locale/fr_FR
