Car DVD navigation system In the current automotive electronic products, car DVD navigation accounts for an ever-increasing proportion. Nearly 40% of new car owners have the need to install car DVD navigation. Therefore, a large number of DVD navigation products are produced and branded, and the difference in product quality is beyond your imagination.
Many DVD products will be screaming as soon as they are installed in the car, and the sound horn will scream as soon as you step on the accelerator. The sound and images are very poor.
Folding sound quality
DVD is used to play music, so the sound quality is very important. Therefore, before purchasing a DVD, be sure to ask how many "V" the front output of this DVD player is, or compare the sound quality of this machine with other DVD players. If the sound quality of a DVD player is comparable to that of a CD player, the price will certainly not be cheaper.
Folded image dosage
There are two types of DVD screens, analog screen and digital high-definition screen. The pixels of the analog screen are generally 240 * 240 or 480 * 240 pixels, while the HD screen is generally 800 * 480 pixels or higher. In addition, good DVDs are equipped with dual optical drives, that is, DVD and CD optical drives.
Folding convenience
Good DVD manufacturers will use better navigation software. Poor DVD navigation is easy to crash during navigation, or the navigation speed is slow, and the accuracy of navigation is also poor. Because good DVD navigation adopts the "dual-core" mode, that is, two independent CPU processing systems are used, so that the two systems do not interfere with each other, the navigation speed is fast, the accuracy is high, and the use is convenient.
