I have tried this but it didn't fix my problem. I will definitely try again!
One problem I was having is that the ringer volume in the truck was low and I would not hear it ring but just see it on the display. I found a way to help this but I don't know if it is a long term fix yet. What I did was have someone call my cell phone when connected to the truck with bluetooth. While the phone is ringing, before I answer it, I was able to turn the volume knob on the radio and turn the ringer volume up in the truck. Someone had said that there were different volume settings for the music and ringer volume. But I could not find a way to adjust the ringer volume other than this. Once I get out of the truck though, the ringer volume on the phone resets to the current volume setting on the truck audio. I am still checking the ringer volume on my iphone and seeing how it changes based on the audio volume level in the truck.
