It's not just Nissan. I have bluetooth problems in my 06 Lexus RX400h as well. Mine is a little "weird". My phone will connect successfully, and all the onboard controls work but there's no audio AT ALL coming out of the cars speakers. Any outgoing or incoming calls go right to the phone instead. So, I can dial out or answer a call but I have to pick up the phone and talk from there. To make matters worse, I have to talk fast because the call will mysteriously hang up after about 1 or 2 minutes.
Tried, everything, factory reset, cleared all assigned phones in my car, safe mode....still doesn't work right. Oddly enough, every once in a blue moon, if I stop and turn off the car, and then turn the car back on and let it resync with my phone it suddenly works fine. Until, the next time I start the car and the whole process starts all over again.
I'm *seriously* thinking of getting an iPhone. My wife and daughters iPhones have absolutely no problem with bluetooth. Both Verizon and Motorola have been useless. I'm on my THIRD Turbo in a year and they've all been the same. Both in Kit Kat and Lollipop.
This will be the LAST Motorola I ever own.
