问：2009年大众Passat Aux不起作用？

你好。为了帮助您找到无法正常工作的辅助线的原因，我建议您进行一些消除过程。如果您有另一台设备尝试将该设备和AUX线插入您的汽车，因为可能是您的iPhone很难传输信号。如果更换设备无法解决您的问题，我将尝试测试AUX线本身。可能通过购买另一个廉价的辅助线或在其他音频设备中使用AUX线。您还可以简单地将iPhone插入耳机，以查看它是否会产生声音以帮助消除过程。您应该能够从视频中显示的屏幕上导航，该屏幕卡在辅助功能上。尝试在CD中弹出或更改广播电台，以确保您可以从该屏幕上脱颖而出。如果您无法摆脱该屏幕，则可能与广播单元本身有问题。如果这是无线电单元的问题，则可能是硬件问题以外的编程问题。 Volkswagen should be able to reprogram your radio for you if this is the case. What I suspect most is a faulty auxiliary port inside of your center console. I’ve seen the auxiliary ports go bad on vehicles less than a year old so it would not be surprising if yours has failed after about seven years of usage. The aux port can sometimes be subject to a lot of stress such as people removing it incorrectly or things leaning up against it while it’s plugged up inside of your center console. That stress could damage your AUX port or cause a shortage in it. To help test the aux port you can try to wiggle it a little bit while playing music to see if that will help.
