Today, I made a call in my truck (2013 F-150) using bluetooth and the Sync system and it was super quiet. I had the volume on the phone all the way up, and the radio in the truck was turned up where it normally is. I later tried another call, to another person, and it was the same issue. Any ideas on what this could be? I deleted the connection, both on the phone and in the truck and set it up again like it was new. It seems like it may have worked, but hard to tell, since I am just sitting in my driveway and it's to late to really call people to test it.
