Media playback. Passengers can use the in-dash DVD player to watch their choice of videos, from DVDs to YouTube. You can also play MP3 and streaming music via Bluetooth, CD, USB, or SD card, giving you plenty of options for entertainment. Apps like Spotify and Pandora can also be used in addition to the basic car stereo.

Easy use. The majority of units on the market have a touchscreen display, making them easy and convenient to use. Some even come with hands-free calling to answer phone calls via Bluetooth connectivity. As an added bonus, you’ll also give your car a major, modern upgrade at the same time.

Built-in navigation. A lot of in-dash DVD players are available with built-in GPS navigation. This is a useful feature if you tend to be on the road a lot and need access to navigation without another device. It also keeps your hands free since you don’t need to pull up a dedicated app on your phone.

Fun on road trips. If you often go on long trips, you know that they can become a bit dull. With an in-dash DVD player, not only can you play movies and videos for passengers—especially good for keeping kids entertained—you can also play music or the radio.

These units are twice as big as single DIN units in terms of height and are ideal for larger center consoles. Thanks to the height, the screen is fixed to the front panel and is easier to see from the back seat. Most units come with an amplifier, a screen, and a DVD player. 

When comparing models, pay attention to the size of the screen. Most range from six to seven inches, but they do go up to nine inches or more. Large screens, if you have the space, are useful for entertainment and navigation features.

The whole goal of adding an in-dash DVD player is to get some multifunctionality to make your life a little easier. That translates into having many devices connected to the player. Some also have built-in apps that communicate with your smartphone, allowing you to sync your address book or read text messages through text-to-voice. Units compatible with steering-wheel controls also offer another way to access the controls.

Excellent, at-a-glance visibility is what you’re looking for, no matter what size screen you end up choosing. Higher resolutions have sharper images, making the screen easier to see and use.
