I have an iPhone 4S and drive a Chevy Volt with Bluetooth capability. I can make and receive phone calls, so I know the phone is "paired" properly with my vehicle. But I would LOVE to listen to Pandora while I drive, instead of the junk on commercial radio. But I get it to work. When I connect the USB cord, the dashboard reads "this media is not available." What am I doing wrong?
Others can correct me if wrong, but Pandora is not output through the USB connection. I recommend using your headphone port and an audio cable (I assume the Volt has a 3.5mm audio input) to listen to your Pandora through your stereo. That is what I use on my 2004 Dakota (works great).
You can look at the info on Pandora's website for info like this. If your stereo is not Pandora enabled then you won't be able to play it through your iPhone using the USB....but as mentioned, you can do so with audio input if your car radio has that port.
You can also check the following link based on the model Volt you have to see if the info provided shows detailed info to make it work the way you want if possible. You choose the specific Volt model that you have (with MyLink, with or w/o Navigation, etc) and then the device you are using.
