It all depends on the type of DVD player you have. For example, the best DVD players are as simple as plug-and-play. You set them on your dashboard or have them mounted onto your headrest, get the power cord, and plug this straight into your car’s 12v outlet. Of course, if you have an in-dash or even a flip-down system that needs to be integrated into your vehicle’s built-in video and audio system, then there will be some degree of installation needed. Installing a car DVD player is quite easy. You may want to disconnect the negative terminal on your battery first before doing anything with your car’s existing system. Next, you can start removing your vehicle’s existing stereo unit. Depending on your car, you may have to remove the panel on the center console. Regardless, it is always best to check your car owner’s manual on how you can install a DVD player. Car DVD players also come with their own set of instructions on how to install the gadget into your car. Some cars may require a kind of adapter faceplate. Make sure to follow the instructions to the letter and use additional recommended wires if needed. Slide the new DVD player right into the slot and secure it into its bracket. Reinstall the panel if needed and reconnect the negative end of the battery cable.
