Real quick, I have been on the information round-about for almost a month. I have a Mazda3 GT with navigation. iPhone 5s would connect with bluetooth no problem ever. Upgraded to a 6s and suddenly have connectivity issues. Phone would sometimes just drop signal. Once signal was lost, there was no getting it back unless you either turn the Car completely off, or hard reset the phone. After getting the run around with Apple blaming the Car, the phone was fixed - no problem now. I had to use itunes "restore iPhone", once the software was downloaded, had to select Set Up As NEW. I think the last OS update 9.3.2 somehow got corrupted. Weird thing is that the phone (otherwise) seemed to be working fine. Just wanted to let all of you know - so you didn't have to spend hours on the phone with people who (sometimes) don't know what they're talking about.
