Many DVD products just loaded into the car, one step on the accelerator, speakers will scream, sound and images are very poor, so remind consumers in the purchase of vehicle DVD navigation products, we should pay attention to the following points:
DVD is used to play music, so sound quality is very important. Therefore, before you buy DVD, be sure to ask how many DVD "V" is in front of the DVD, or compare the quality of this machine with other machines. If the DVD sound and CD player sound quality to compete, the price certainly not cheap where.
DVD screen with analog screen and digital high-definition screen 2. Pixel simulation screen is usually 240*240 or 480*240 pixels, high-definition screen is generally 800*480 pixels or higher. In addition, a good DVD is the use of dual drive matching, that is, DVD, CD two kinds of CD-ROM.
Good DVD manufacturers will apply relatively good navigation software, poor DVD navigation easy navigation in the process of crash, or navigation speed is slow, navigation accuracy is relatively poor. Because good DVD navigation uses the "dual core" mode, that is, the use of two independent CPU processing system, so that the two systems do not interfere with each other, navigation speed, high accuracy, easy to use.
