Ok - I finally tried this today ( I have an old ipod I have been using). I didn't have to switch any settings on the phone except what I wanted to play - you just have the select the correct option on the car. I was able to do front, back, start, stop, and volume. I found where it says you can index your bluetooth devise but never could get it to start. discouraging to not even get track name or info displayed, but it works fine. Just kills your battery so I don't see that being something I will do often. I am curious to try Pandora later today. Turns out the app wasn't on my phone.
