The biggest difference between the 7 Lite and 9 Lite is that the former has 7-inch screens. They both lack battery packs (optional extras), they’ve both been safety tested to ensure they won’t endanger passengers in a crash, and they both comprise one unit with a built-in DVD player and one that’s just a display (so they can only play one movie at a time). Annoyingly, the player and display are linked via the headrest mounts, which have to be fitted to use both screens. We do love the high video and audio quality.

Verdict Four stars
