New iPhone Xs does not sync with Toyota Sienna via bluetooth
I recently purchased an iPhone Xs, and tried to sync it with my 2014 Toyota Sienna. It actually pairs, but then disconnects randomly or stays connected but simply never works. I can't make or receive calls via bluetooth in the car. I have upgraded to the latest version of IOS. Didn't help at all.
However, I can play music from my iPhone over bluetooth and that works fine.
Any ideas???? thanks
