iPhone 6 not connecting to car Bluetooth

For everyone having this issue, this worked for me. My phone too was not showing the PIN for my Ford Sync. I got angry and just spoke 4 random numbers into my Sync and my PIN pad suddenly appeared on my phone. I typed in that number and it connected. The SYNC wanted me to tell it what number I wanted to use. Hope this helps someone out there as I see this issue on several vehicles. Try it and it might work for you.

Hello,

Thanks for your post.

I got my iPhone 6 last night. I had an iPhone 5S before running iOs8.

I have 2 cars: 2013 Ford CMAX Energi and a 2014 Porsche Cayenne.

After upgrading to iOS8 on the iPhone 5S, no problem to place and receive call on the CMAX. But on the Porsche it was a nightmare. The calls started then after two ringtones the call disconnected. I had to remove all the devices on my iPhone 5S bluetooth profile and the same on the Porsche. After the pairing was done I push the home button and on/off button. Then the connection was ok.

Now with the iPhone 6. The nightmare is back.

I was able to pair and connect the iPhone 6 on the CMAX. But as soon as I try to place a call, I hear the first ring, then the call is disconnected. Ford Sync even shows me that I just have one reception bar when in reality I have full reception on the phone.

Now for the Porsche, same issue. I was able to pair the phone. When I try to place a phone call after one ring the call is disconnected.

One the two cars I reseted to Factory setting both Synch system and PCM. Reseted the network settings on the iphone 6. Remove all the bluetooth devices, restored the phone. Then pair again the phone same issue.

I tried the wife' iPhone 6 same issue...

Based on this troubleshoot and taking under consideration the iPhone 5S with iOS was working it looks like there is an issue with the iPhone 6.

I was just on the phone with an Apple iPhone Tech support guy who just talked to one senior support guy. He just told me that there is a compatibility issue between the bluetooth used on the iPhone 6 and some car navigation/bluetooth. He told me that the issue is coming from Apple. And a solution maybe be provided at a later time in a patch.

This is where we are standing right now...

I just brought my iPhone 6 home today and I can't get it to pair with either of my Bluetooth devices.

My car (2014 Honda CRV) has a factory hands-free setup that worked fine with my iPhone 4s. When I follow the instructions in the owners' manual to pair the iPhone, the car can see the iPhone, but it keeps giving me an error message that pairing them failed. It suggests that, if that doesn't work, I should try doing it from the iPhone--but the iPhone doesn't even show that it sees my car system.

Then, I have a Bose Bluetooth headset (series 2) that also worked fine with the 4s. When I turn it on, the blue light blinks slowly, which means it's discoverable. But when I try to pair it with the 6, sometimes it will show "Headset" on the iPhone Bluetooth settings screen, and sometimes not--sometimes the wheel just spins and spins and nothing ever shows up. When it does show that it sees the headset, if I choose it, a few seconds later the iPhone tells me that pairing failed, and I should check to see if the headset is on (it is) and discoverable (it is).

So far I've tried cycling the power on everything; putting the iPhone on Airplane Mode for a few minutes, then turning that off; resetting the network settings on the iPhone; taking the iPhone out of the case; and a lot of swearing (didn't think that last would help, but I felt better). I'll be calling AppleCare in the morning.

Guys after playing around with it right now i was able to solve this problem! this is what i did...for my 2011 honda accord...give it a try on your car.

1. turned on BT on my iPhone 6 which had already paired to my car before as i mentioned in my last post

2. turned on my car

3. went to handsfree setup and deleted all the phones that were stored in there...i had 5/6 stored...one of them being mine...the other 4 being from previous owner i would guess. i deleted each and every one...so i was back to 0/6.

4. then went to my iPhone and tapped the 'i' next to handsfree under bt settings and did 'forget this device'.

4. then handsfree in my CAR automatically asked me 'do you want to pair a new phone'. i said YES.

5. i paired my phone using the 4 digit code that my car displayed.

6. then it said 'connected' next to 'handsfree link' on my iPhone like before...but this time it actually worked! i made a phone call as well as received one and both came out of the car speaker.

hope this helps you guys! give it a try!

Here's a post I made earlier today of what worked for me. I'm trying to let as many frustrated people know as possible. I'm sure I'll be accused of "flooding" or "spamming" the boards with this post but having navigated and wading through the communities I'd hate for another possible solution to get buried.

Iphone 6 iOs8 - Bluetooth Issue - Vehicle - Solved

On my VW (Sharan) I got it to work as follows.

1. Deleted all all the old profiles from the car (a bit if a hassle as for some reason you have to connect a phone before the option to delete profiles appears - used a previously paired older phone)
2. Reset the network settings on my iPhone
3. Switched the ignition off completely - remove the key!
4. Insert key and start car - you now have 3 minutes to complete the pairing.
5. In bluetooth settings the car is now visible. Touching it prompts for a password. '0000' is default.

Good to go.

OK I just made mine work.

IPhone 6S to Mazda

Key Steps:

1. Open up settings blue tooth on your phone and note that a little work in progress circle will be whirring
2. follow what car book says about pushing buttons to do pairing and start doing those steps
3. As another person in this site said I deleted the old phone from the car but the book says you can have 7 devices so may not be critical.
4. On the car radio (had to be on with ignition on) I clicked through to BT Setup then you had to turn the knob and choose insert Pin code; I used 1234 which was put in by pushing the first button once, the second twice and so on
5. THEN the step I tumbled to is this. On the phone the Work in Progress circle came up and eventually it said Mazda as it found the signal. For the first six tries we thought good here we go but NO we had to touch that word on the phone screen and another little Work in progress circle came up opposite the word Mazda on the phone.
6. Then the phone called for a PIN code so I inserted the same code I put into the car ie 1234.
7. I waited maybe 30 seconds and Bingo the Phone screen said paired and I could make a call

So the devil was in the detail

Update--I got the phone to pair with the Bose headset, at least! I went back to the Bose website and found a link to download a firmware update for it. After I installed it, the headset showed up by name on my iPhone--not just a generic "headset" label. It paired then on the first try. Apple doesn't seem to want to let me post the link to the Bose website, but if anybody else has this headset, it's not that hard to find.

So now I'm wondering if my car system has the same problem...and how to get the software update for it! I'm still calling AppleCare tomorrow to see if they have any ideas, but I expect I'll be calling Honda on Monday.

And now I've gotten my phone to sync with my car. I went out this morning to try it again, and to call AppleCare if necessary. I looked at the car's manual again and realized I was looking at the instructions for pairing a phone for the first time with the car--and on the next page there were slightly different directions for pairing a new phone. I went into it that way, deleted my old phone, and this time the car found my new phone with no trouble at all.

Now, to see if I can pair the new phone with my Bluetooth speakers at work...wish me luck!

Having same issue myself and its very frustrating. Just like many others here...i had a 5S until friday on iOS 7 (not 8) and it was working perfectly fine in my 2011 honda accord which has handsfree calling capability. with the iPhone 6, it even connects to the handsfree but it doesn't WORK! when i try to make a call or when a call comes, i can't hear anything from the car speakers and have to end up taking the call on the phone itself. I can't fig out if this is a hardware (6 vs 5s) issue or software (iOS 7 vs iOS 8)....because it was working on iOS 7 iPhone 5s...but not on the 6 with iOS 8....but i am HOPING its iOS 8 because from what i read online both 5s and 6 have same bluetooth version (4.0)..and not sure calling honda about my car bluetooth would be any good...so really hoping apple releases a fix for this..i heavily rely on this.

Add aftermarket to the list of incompatibilities as well. Kenwood DNX7100; working fine with iOS 8 and a iPhone 5; iPhone 6 not as well. Siri still comes through the speakers and the microphone works but phone calls do not route to the speakers and music keeps playing. You can call from the car stereo and the phone makes the call, but it does not transfer / hand off the voice / microphone. Very frustrating. And the Kenwood head unit and bluetooth interface are both fully updated as far as firmware updates.

Figured it out. Went to Settings -> General -> Reset All Settings (perform task) and then after reboot Settings -> General -> Reset Network Settings (perform task) and let it reboot. After the phone started back up, I again paired the bluetooth devices, and they auto connect properly and both Siri and phone calls are 100% working as before from my iPhone 5.
