Due to strong decoded chip inside, the device can support high quality sound source such as main MP3 and WMA, and support video format like MPG、MPEG、AVI、MPE、DAT、VOB、DIVX、DIV、XVID、MP4、M4A etc. (That is not to say above mentioned file extensions always can play, that mainly depends on its encoding method, generally speaking, the product supports the video files which only if MP4 and PDA can play, furthermore it does not support high-definition video playing files.). In addition, it also supports playing pictures in JPG or JPEG format, and the playing time interval is 5 seconds.

The Directory Management and the Playing Mode:
One file folder created is as One Disk in daily usage. According to playing sequence, it is playing from the first file folder or file under the root directory inserted by the car owner by the help of USB port or SD slot. One of audio or video format files will be activated and opened automatically as CD1, the following file folders will be opened in sequence, after CD1,it is CD2, CD3 ……in that way, according to the folders created order, the playing folders or files of root directory is always takes advantage of others.

Video input or output:
The product has the video input and output function, and demanding the display has its corresponding Video In port to match .You can connect one end of video input and output wires with the car’s head unit back of AV Output port, and connect the other end with the display AV In. The display video will be switched on automatically after operation. The device can work normally even without display.     

This port is used to play auxiliary music source from external equipments such as MP3 player, MP4 player, PSP, or Mobile Phone (but a special wire is provided for connection). When you use Aux In, other format music SD or USB does not work for the time being temporarily. Therein the working indicator light will be changed occasionally, which means that it is in the working status of Aux In. While you pull out of the Aux In wire, the device can resume playing from what you have paused last using SD or USB.

Exact Power Failure Memory:
The device supports exact power failure memory for the music playing in the use of SD or USB. If the power is suddenly off or you switch to other type to play other sources models such as CD, AM/FM or else by chance, the paused music or video will be continued to play when they are in normal again. Even if the files in SD or USB have been changed, last position memory still remain, however, the device does not support the exact power failure memory in the way of Aux In.

How to Operate and to Use the Device: 
1. First of all, you need to format the music storage through FAT16 or FAT32, next, you can build up the music files according to your favor in the music storage. You can enjoy the first built up in the music storage. For the sake of usage and management, we recommend that each created files is added no. 01, 02 and so on, in order to get music files playing as desiring. (Please look at the following picture)

※Important Note:
 Take the left picture structure as an example, if the root directory has not file folders or files, the playing order is as per showing picture. The root directory has priority to perform the files or files, therefore we advise you to put your favors under that directory.
 In order to control and read the files conveniently and as effectively as possible, we recommend you not to create and to save more folders or files each time. Less than 20 created folders and 199 files per folder are acceptable. If overload, some car main audio devices can not display and open the extra folders or files, and please do not panic because this is not problem of machine.

2. Turning on the car main audio device, you need to switch the mode to CD by pressing the CD (CDC or MODE) key, after that you can enjoy the music audio or video from the car digital AV changer. It needs to be pointed out that some car models need pressing the FM/AM key first, then pressing the CD (CDC or MODE) key, and the switch will be achieved between MP4 changer and car original CDC changer.

3. After the working indicator light will be on or blink quickly for 3-5mins, it will play the first music from the device automatically. If the light is occasionally on or off, that means the device is not in real working state although it is electrical. If the power light is off completely, you would need to check that the power of the main unit is turned on or not and the wire harness is connected properly or not.

4. The operation of MP4 is similar to the controls on the main audio device. Usually most of the buttons on the audio equipment can direct to achieve the results as your desire, but some type of cars’ need adjusting correspondingly, for example, the button like FF or REW is changed to the control keys for next or previous files, for some cars, it even work under the condition of pressing the keys about 1 second. It is pointed out that the MP4 changer will play next files after the current files automatically.

5. Aux In is superior to SD or USB when they are working at the same time. When it is playing from SD or USB, it will switch to play the external auxiliary input automatically if AUX IN is required all in suddenly. In addition, the SD is as same as the USB on the priority order depending on its sequence order.

Important Note:
 The exterior surface is about 48℃ under the high temperature when it is still working.
