Buying a car DVD? Here are some things to keep you on track...

Make sure what you're opting for is future-proof. A system that foresees where this technology is heading to is certainly a better protection for your investment. For such systems, you can upgrade without penalty.

Make sure it is compatible with your headunit unless you have other plans like buying another headunit if your DVD cannot fit or if it does not let you take full advantage of your DVD.

Make sure it supports your DVD format. That is, make sure it can play DVD-RW if you need it to play DVD-RW. Some may not. How do you do that. Simple! Take a DVD-RW (or the desired format or formats) and make sure it can play it before you buy it.

Component systems are a lot more expensive and are also of a higher quality. They are also more flexible when it comes to installation. They can be installed in the dash, behind your headrest or in your car's ceilings among many positions.

Make sure you get a good antenna. It will ensure good reception while the vehicle is in motion. Dual antennas are usually better.

And, please, for your safety and others, make sure your DVD player is installed totally out of the driver's view. On the other hand, ensure that certain safety precautions are implemented. A good example is a connection that ensures the DVD player switches off once the ignition is on.
