近年来,随着汽车娱乐系统的发展,越来越多的车型装备了带有硬盘的音频系统主机。带硬盘的主机可以将导航地图、音频、视频文件、通讯录信息、语音备忘录等数据存储在车内,以便驾驶人随时调用。由于主机一般都由非汽车厂家的其他生产商供应,且内部结构较为复杂,所以修理人员一般不对其进行拆解修理,如果主机出现了死机、黑屏、播放不顺畅、自动重启等故障,在排除了供电、搭铁、总线信息、视频和音频输入等问题之后,一般是更换主机总成。
In recent years, with the development of car entertainment systems, more and more models are equipped with audio system hosts with hard disks. Hosts with hard drives can store navigation maps, audio, video files, contacts, voice memos and other data in the car, so that drivers can call at any time. As hosts are generally supplied by other manufacturers than non-auto manufacturers, and the internal structure is more complicated, repair personnel generally do not disassemble and repair them. If the host has crashes, black screen, playback is not smooth, auto-restart and other failures, The power supply, ground, bus information, video and audio input and other issues, the general is to replace the host assembly.
