So the other day I went and dropped $7 to get the adapter to play my iPhone through my car stereo. It sucks because I already have the cable in my car and have for some time, but with the iPhone, it has a recessed jack on it so you need an adapter. Anyways this was my first time really using the iPod features of the iPhone… And I guess there is a bug in the system, sometimes when you unplug the connection on the phone the audio sometimes stops working. As you guessed it, this happened with my phone today. Thankfully with the help of Google, I was able to find the fix, and here it is.
Plugging in and out the headphones several times until the audio starts working
Simple as that.
