Car DVD navigation system In the current automotive electronics products, car DVD navigation accounts for an increasing proportion. Nearly 40% of new car owners have the need to install car DVD navigation. Therefore, a large number of products for the production and OEM of various car DVD navigation emerge, and the quality difference of the products is beyond your imagination.
As soon as many car DVD navigations are installed on the car, they will scream as soon as they step on the throttle. The sound and images are very poor. Therefore, consumers are reminded to pay attention to the following points when purchasing car DVD navigation:
Sound quality
DVD is used to play music, so the sound quality is very important. Therefore, before choosing a car DVD navigation, you must ask clearly how many "V" the output of this DVD player is, or compare the sound quality of this machine with other DVD players. If the sound quality of the car DVD navigation can be compared with the sound quality of the CD player, the price will certainly not be cheap.
Image dosing
There are two types of DVD screen: analog screen and digital high-definition screen. The pixels of analog screens are generally 240 * 240 or 480 * 240 pixels, while high-definition screens are generally 800 * 480 pixels or higher. In addition, good car DVD navigation uses dual optical drive configuration, that is, DVD and CD two optical drives.
Convenience
Good DVD manufacturers will use better navigation software. Poor car DVD navigation is likely to freeze during the navigation process, or the navigation speed is slow, and the navigation accuracy is also poor. Because good DVD navigation uses the "dual-core" mode, that is, two independent CPU processing systems, so that the two systems do not interfere with each other, fast navigation speed, high accuracy, and easy to use.
