Bluetooth issues with iPhone X?

First part - mostly yes, doing a full reset using iTunes to restore the OS and setting up as new has it working almost as well as my 'old' 7Plus. I generally have it plugged into the PCM using USB so the audio quality there is fine. I do, however, notice some noise on Bluetooth with Calls and when Waze breaks in to do an announcement. I haven't tried playing audio using BT only - will try that on my next drive and let you know.

Thanks Garry. I setup the iPhone X as a new device. Like you I use "both" connections in the car -- Bluetooth to PCM for phone and USB port in glove box for power and direct iPod connection. The static occurs when talking on phone, getting Waze prompts, etc. Given the phone was already setup as new, and I setup the phone as new device when connecting to the PCM, any other thoughts based on your recent experience?

BTW 1 -- I haven't even tried running Harry's LapTimer yet or connecting to my OBD-II dongle and track GPS. Is the issue you are experiencing independent of your OBD-II?

BTW 2 -- I wish Waze could show up on the display to the right the tach, but that's another thread!

Thx again, Garry.

Hi Alan,

Ok, so we are essentially at the same point. Just took me a while to get here :-) I first tried by restoring from backup and that ended up being a multi-week nightmare.

I have my Automatic OBD-II dongle attached now - that seems to work fine now that I used iTunes to reset and then setup as new.

Completely agreed on 'BTW 2' - would love to have Car Play... and better integration with the center-right display. I found a way to add car play - but it requires opening up the PCM - not to mention just taking out the PCM requires disassembly the center console and air vents. I may decide to do that at some point - definitely not till after the CPO Warranty expires... Its also sad that one can't just replace the PCM with an aftermarket device..

BTW 3 - the only items i wish I had is Car Play and Adaptive Cruise... and that Waze supported Car Play... but that is another thread... :-)

So deleting my old phone name & giving the iPX a new paired name seems to stop the BT drops in my car. Yay!

However, Waze nav app's sound does not go out the car's speaker in both Media or Radio setting.

This did NOT occurred on my prior iP6S+.

So far have not been able to isolate this anyone else on the web.

The latest 11.2 iOS update may have fixed my phone audio Bluetooth issues. That is the only thing I changed on my end and so far so good.

The audio selection on the phone now showed my iPad and Bluetooth device as options and that is a good sign. I did not have to select the Bluetooth device as it automatically used it for audio. Hopefully, it is fully resolved as a result of the update. We’ll see.

Update after iOS 11.2: BT dropping still remains. I have deleted the pairing and done a new one, but the problem remains. As I was gathering Sys Diagnotics to the Senior Support, I’ve giving then for both iOS 11.1.2 and iOS 11.2

Let’s hope that they find the root cause and solves it for the next update.

I had a devil of a time getting bluetooth to sync with my SkullCandy wireless headphones, but finally succeeded. I have had no luck, however, getting the X to _consistently_ sync with my Subaru Forester. It will pair, but when I turn the car off and back on again, my X can't be found and I have to pair it with the Forester to get it to work again. I have a pal who has paid a bundle for a set of hearing aids that work with the X and the X will simply not recognize them. Clearly Apple dropped the ball on bluetooth implementation in the iPhone X.

Not to but into your thread, but on my Forester, it required that I delete the old pairing (iPHone 6, worked perfectly) and set up a new pairing with the iPhone X. Did so, but between restarts of the vehicle, the iPhone X and Forester do not recognize one another: radio displays something like <No BT device present>.

GOOD NEWS FROM MY END AFTER HAVING INSTALLED IOS 11.2

1. Porsche PCM 3.1 with Software 4,76 is now working!!!! Aha radio service, real time traffic etc. are back!!!!!

2. BMW 7series 2016 seem to work as well!!!!

3. Bluetooth: I disconnected the device, changed the Iphone name and connected as new device. Perceived quality is better than before but will check more carefully tomorrow:

I recommend you to try agin after 11.2 is installed

If you have updated to iOS 11.2 and tried all the other suggestions listed by Apple and in this thread and it still is not working then you need to contact AppleCare and give them all of the details of the device you are not able to connect with. Besides the new iOS the iPhone X (and iPhone 8/8 Plus) has a new Bluetooth chipset with Bluetooth 5.2. There is no way Broadcom or Apple can test with every BT device that exists so you need to contact them so they can get information from your iPhone and about your device.

If you continue to dface issues even after the 11.2 installation I recommend to

1. back up your machine

2. reset iphone entirely back to factory settings and set up as new iphone

3. delete all BT connections / devices in your car or where you are using it

4. try with the "factory reset" phone.

Not working:

5. if possible, try with someone elses Iphone

If that is not working you have a solid startiung point for a device change @ the Apple store.

11.2 helped me with Porsche PCM 3.1 in a 911 4,76 SW release and partly in BMW 2016 7 series, whereb APPs like audible are still disconnecting every now and thn. BMW knew about this and will install a sw update. Wireless charging works well in the BMW

Indeed much effort for such an expensive device.

Hey, what OBD II you’re using? I can’t connect to my BT1a in my Lotus, never had problems with the 6s. The car stereo/ hands free no problems. Pandora is a battle (even without connecting to anything).

I am having an issue where my headphones say they’re connected, but I hear nothing and I cannot press play on Pandora. If headphones are disconnected, or I use non-wireless headphones everything works fine.... it’s clearly an iPhone X Bluetooth issue. Everything worked great on my 6s two days ago...

Try going into control center and turning off Bluetooth, wait a minute then turn Bluetooth back on. Confirm in settings that your still connected if not then reconnec. This worked with a TomTom Go problem I was having.

My iPhone X will continue to drop connection to my mercedes Bluetooth and even sometime not re-connect until I select the phone in the device list again.

I previously had no issue with my iPhone 6 holding the connection continuously and have deleted this device from the list of connectable devices as advised on this thread, however this issue is still present and occurs daily.

Becoming really annoying now.....
