iPhone 6 BlueTooth issues with iOS8

iOS 8.1 beta is fixing the issue.i am testing it for 2 days

I have had the same issues as everyone here. I felt compelled to share my findings after some very lengthy testing.

I have a 2014 Jeep Grand Cherokee running the latest Uconnect Firmware (14.25.5). I too upgraded to iPhone 6 and quickly realized there was a Bluetooth issue so I did some testing. I used an iPhone 4S, iPhone 5S and a new iPhone 6. iPhone 4S was not upgraded to IOS and was running IOS 7.1.2. Connected this phone up to my Jeep and everything works like a charm...Upgraded to IOS 8.02 on the iPhone 4S and same problem as iPhone 5S and iPhone 6 running IOS 8.02. Music seems to stream with no issue, but making or receiving calls seems to work for about 10 seconds then quits and transfers call to phone only (no audio in Jeep and shows disconnected on Uconnect screen). Some times upon connection it shows automatically redialing last call without connecting. Next step was to revert all three phones back to 7.1.2. Once completed all worked as they should...I then installed IOS 8.0.2 on the three again (iPhone 4S, iPhone 5S and iPhone 6) and the problem quickly returned. This is definitively an IOS 8 issue. Not a phone or hardware issue. I then tried some of the different things that people have tried including "Reset All" which does work. That is until you power cycle or sync with iTunes and then the problem returns. After playing with multiple different scenarios I have found the only thing that seems to hold even after a power cycle, reboot or iTunes sync...Sign out of iCloud and power cycle the phone then re-pair your device.

This issue seems to be tied to iCloud and IOS 8 platform.

Steps:

Delete Bluetooth profile on both the iPhone and the vehicle in question.

Sign Out of iCloud on the device you want to pair.

Power Cycle the phone

Pair phone with vehicle...Problem solved. No issues with power cycles, iTunes sync etc...

These steps above have been tried on 4S, 5S and iPhone 6 with the same success running IOS 8.0.2

Note the problem will return if you sign back into iCloud and then power cycle, reboot or sync the phone to iTunes.

I realize some may not be able to live without iCloud services. iCloud can be used, but only after you have paired your device. Then, as long as you do not turn the phone off or sync with iTunes it will continue to work. For my Jeep this seems to work. Much easier then a "Reset All" every time. Not sure if other vehicles will have the same success? In any event, looks as though Apple has a little issue here that needs to be addressed.

Thank you....I can't believe it but it worked. I logged out of iCloud, deleted all my Bluetooth connections. Cycled a reboot. Went to my benz and deleted my iPhone profile. Reestablished a Bluetooth connection and boom. Like new.

really ***** that iCloud does not connect, but it does the trick as I am in the road about 3 hours a day.

Thank you @tflemin2 ✌️

OLTURBO,

When you mention the thing you were sure did it for you was to delete your 'car phone' to its factory settings,

are you referring to your iPhone 6 back to factory settings?

Great to here. You can sign back into iCloud without issue here on out as long as you do not power cycle the phone or sync with iTunes. If you do, you'll have to go through the steps again. The trick here is to establish the paired profiles without being signed into iCloud. Rebooting or syncing negates or corrupts the profile somehow?

hi, i'm happy to report that after 4 days of testing, my bluetooth connection is still going strong, not a single drop call.

the 2 important things are:

1. any unused devices should be deleted from icloud "find my phone" page.

2. all devices logged in using the same apple id have to appear in your iphone 6's bluetooth setting. this has something to do with that hand off function where you can answer your call from ipad when your iphone is nearby.

Thats great 🙂

another fix is reset your car stereo to factory settings as per my post above, this works without having to do anything with iCloud.

at last 2 fixes 🙂

I tried resetting my nav system twice: once through "Reset to factory defaults" and then with a paperclip in the reset hole (lost all my SiriusXM pre-sets). Nada. Still don't get a cellular signal on the iphone 6 once it's on Bluetooth.

resetting your car system alone probably will not solve the problem. i did that too many times and nothing worked along with other suggestions from other threads.

until i saw that apple support article i posted above, gave it a try, and holy cow! it has been working for 4 days now.....

I'm having trouble understanding the directions in the article. When I check under Bluetooth/My Devices on my iPhone 6, I see my car and my Bose speaker listed, that's it. My 2 iPads and my Macbook are NOT listed. When I go to icloud.com under Find my iPhone, I see all my devices listed (including two that are off line). What am I supposed to do now?

Did you delete the old pairing from your phone first then do a hard re-set on your phone, then pair up to your car again from scratch?

Yep, tried that yesterday . . .

Its worked for me on 2 separate cars with 2 separate phones. I'm on day 2 and everything is working 100%. I've switched the phones off to see if that stops it from working again like a previous fix did and it hasn't affected it at all, both cars and phones are working exactly how they used too do.

are your ipads running ios 8?

if they're running ios 8 and you're using the same apple id as your iphone 6, then they need to be shown in your iphone 6's bluetooth set up menu. to make them appear, you need to have all devices on, with their bluetooth on, place them nearby each other. if they don't show up, you can try power cycle your iphone. it worked for me. (of course all of your ipads need to be logged in with the same apple id).

if both of your ipads are active (you're using regularly), then you don't need to do anything there. if you no longer use them, then they need to be deleted from your "find my device" page in icloud.com, and you need to log your apple id out of those devices.

before proceeding to next steps, you need to delete your car from iphone 6, as well as deleting your iphone 6 from your car's hands free system.

power cycle your iphone, then you can try pairing with your car again.

hopefully i explained myself well.

Very strange........it's worked for my 2 cars and phones and friends have tried it too and theirs is working fine.

we need Apple to sort this for everyone's sake.......roll on 20th October for this update 🙂
