While not the fit and finish of the number one pick, the Audiovox or Jensen custom series does approximate the factory size and color of most vehicles. Just like the number one pick these headrest monitors simply replace the existing headrests.
These systems include a DVD player in each headrest and inputs for video games and iPods. It also includes two remotes so when one gets lost you’ll always have a backup.
I place this system as my second choice because it installs with very little alteration to your vehicle and maintains a look that does not raise that much attention to thieves. Also, I listed both brand names as the systems are identical and the name on them only depends upon where you find these units.
