能从SD卡读取MP3文件，并且识别后通过LD3320播放MP3，具体使用只需新建一个.ini系统文件存在sd卡，在里面设置好关键词并且所需播放的MP3文件即可(Read MP3 files from the SD card through the LD3320 play MP3 and identify specific use simply create a new the ini system files sd card exists inside set keywords and required to play MP3 files can)

Foreword The use of reprogrammable memory technology in vehicle electronic control units (ECUs) has increased in recent years, and is expected to continue in the future. Use of this technology has increased the flexibility of being able to use a single ECU hardware part to be used in many different vehicle configurations, with the only difference being the software and calibrations programmed into the unit. Reprogramming of those ECUs in the service environment also allows for ease of field modification of system operation and calibrations. Variations in reprogramming capability and the multiple tools necessary to reprogram vehicles are a burden on aftermarket repair facilities that service different makes of vehicles.
