iPhone and Etune

Question for you tech savy people. I plugged my phone in with a USB cable and tried to play some tunes. It would show the song playing and the album art on the Etune screen but no sound. Do I need a cable that plugs into my phone's headphone jack?

 

You shouldn't I plugged my ipod touch into it and bang music. Oh and nice ride just bought the same rig.

 

What are you playing the music from on your iPhone? Music stored on the phone, iTunes Radio, Pandora, etc.

Mine gets goofy sometimes if it starts playing an Internet-based music feed (iTunes Radio or Pandora) and then I pull away from the house as it switches from WI-FI to cellular data.

To resolve it (most of the time), I start playing a song stored on the phone, then switch back to whatever it was I was trying to play before. Also, sometimes changing the track once or twice from the headunit fixes it.

 

Yes, trying to play songs that are stored on my phone.

 

I dunno about that one, then. Which iPhone and iOS are you using? Will it play if you connect to the truck via Bluetooth?
