My iPhone 6 works fine via Bluetooth for music, but when making phone calls the volume on the speaker can go from normal to very faint and back to normal.

Has anyone else experienced this? Solutions?

I don't use my phone as a rule in the car so probably only made a handful but when I did I never had an issue with the volume adjusting.
I played around when I first got the car with default sound levels but that shouldn't impact variations in volume? Signal strength good?

Is route guidance on and cutting in with nav instructions (but volume way down on it)?

Signal strength is good and route guidance is not on. I don't make many calls from the car, but when I do, I'd like it to work!
