So the app didn't work for me without changing up some settings. I spent about 10 minutes messing around with it and finally got it to work. Now my phone connects to both car voice and bt media. I had to change the "Settings Screen Action" to "Enable Bluetooth." Also, I unchecked "Set Last Device" and made sure the bt media device was first on the list for priority.
Kind of pathetic I had to go through this when all I had to do with my iPhone 4S (2 years old now) was get in my car with bluetooth enabled.
