My 2015 Mazda 6 doesn't import all my contacts from a Sprint S5. It gets almost all of them - maybe all but one. No contacts are on my SD card. The one that I really notice as missing is an Outlook/Microsoft exchange server contact, but plenty of others make it across. I have decoupled and recoupled the phone and the car.
What else should I look at?
