Q: iPhone 6 bluetooth not working correctly with Nissan

My iphone paired fine to my Prius bluetooth, but I was having two issue after: 

when I was listening to music, i got a text message and my phone when black and then white with the apple logo and wheel spinning.  And then the music came back on and I could view the text on my phone

when I was on a call using the bluetooth in the car, another call came in, I was going to ignore the call and keep talking on the original conversation and all of a sudden I could not hear the person talking and they could not hear me.  I grabbed my phone out of my purse and switched it said it said the source was still on the car stereo/bluetooth.  I switched it to speaker phone and the person was still on the line, but said they could not hear me either. 

I spoke to an Apple Support Senior Advisor today and they told me to go to Settings > General > Reset > Reset All Settings (first option).  I did not lose any data, but had to reset my wallpaper, alarms, notifications, etc.  I tested out the music/text issue and it seems to be gone.  Haven't had the opportunity to test the call waiting issue, but hope that it is gone now too. 

As frustrating as this new iphone  6 has been I will say that I have had a great experience with apple support over the phone!

I found that 'Reset All Settings' worked well to get it working but restarting the iPhone after that point and I ran into the same problems again.

I just tried something that may have worked.  I previously reported problems connecting to my Nissan and BMW.  I tried again by (1) doing a reset all settings in my 6+, (2) delete all previously connected phones on my Nissan, and (3) re-connect my 6+.  So far it is working for my Nissan.  I have not tried my BMW. Good luck!

Everyone including me are finding little workarounds.

The bummer is that the workarounds do not persist.

Typically there are ways to purge your settings (factory reset, reset all, logout of icloud then reset)

These all fix the problem for a short while, until you reboot your phone, resync with itunes, leave and re-enter your car, etc.

After many resets, I am just going to wait for a software update from Apple, because it is clearly needed.

If you are having issues and using iCloud on your iPhone, erase the paired device from your phone and from your car, then disconnect from iCloud on you phone (No need to erase data as iOS will ask)

Then reconnect to iCloud on your phone (simply put your username and pwd) and pair your phone again with your car system.

This worked for me.

Having the same problem with my GMC Acadia.  It will connect but after it dials it drops.  I have reset factory settings, deleted device from phone and car and finally got it to work.  Next morning, same problem. 

The new 8.0.2 update DID NOT FIX THIS ISSUE AT ALL. After you power off and on with the phone, same issue as the 8.0, all 3 of my cars lost Bluetooth connection and shows no signal at all.  Good job Apple, what a lousy update you guys did.

2011 Lexus ES350

2011 Subaru STI

2012 Mercedes E350.

I had same problem after reading this thread I reset networking settings and everything now works.

May be turning off iCloud and then updating to 8.0.2 would fix the problem?

I have the same issue with my 2009 Nissan Armada LE. I went through all of the aforementioned steps and nothing worked. Tried it again and I noticed that when my phone went to 4G I could make a call, but there was no audio from the vehicle.  As soon as it went back to LTE, I fell back into the "No Service" from my vehicle.  I even tried to update the "Name" of my phone under Settings>General>About>Name and nothing worked. This has got to be a SW issue that a patch should fix...at least I hope so!!!

I agree. I made them give me a new phone. I paired it for a few minutes and then turned BT off.  I think this issue took a back seat to the service outage issue that people starting getting after the last update.

If as you say you are the "biggest Apple cheerleader on the east coast," one has to assume you've been around a while.  And if you have, you know that Apple addresses issues, especially one like Bluetooth and especially since it's been widely reported in the press as soon as they have a solution.  The 8.0.2 update released was two-fold and Apple was pretty specific on what it addressed, which was to make the Health App work and to correct the mess from the release the day before.  There was no mention of Bluetooth in the release, likely because they don't have a release for that ready yet. 

It's still unclear to me why some people are having Bluetooth issues and other's like me are having none.  My two iPhone 6's paired instantly with both our cars and we also both have Bluetooth headsets which paired instantly.  But, I'm sure Apple will figure out where the pairing issues are, you just need to be patient.  Ranting won't help you in this situation.

I'm appalled to find out Apple has yet to address this. I returned to Apple store and they kept insisting it was my car, not the phone. Let me get a ticket for being on the phone while driving (if I couldn't pull over), Apple will be getting a bill.
