When I plugin my iPhone to the USB port, sometimes the speakers wouldn't output any sound.

1. iPhone shows the song as being played through dock connector.
2. Audio system in the car shows the song as being played.
3. Increasing or decreasing the audio level also doesn't help.

Changing to FM/AM, pausing the song on iPhone and then changing back to USB connection or some combination like this helps me get back to music on iPhone.

Is there any problem with my car or is it some standard procedure that I'm missing with the Acura RDX?

 

I've noticed that with my iPhone too. Usually unplugging and re-plugging the iPhone in solves it. Sometimes I need to do that twice to solve it.

I think when I encountered this was when I was getting in, I turned on the auxiliary power (engine not running but radio powered as well as windows). I then connected the iPhone, and while the stereo started to recognize the phone, I started up the engine. I think that may temporarily cut the power to the stereo, which left it in the middle of communicating to the iPhone.

 

I have the same problem with my 2010 TL w/ TECH.

I plug in my iPhone through the USB jack and the audio starts playing through it. Then moments later (seemingly randomly) it'll stop and won't restart. Nothing I do will get it to restart. I have to unplug it and re-plug it in though the USB cord to get it to start playing through the stereo again. I assume this is a conflict with the bluetooth audio. Anyone figure out how to fix it?
