My brand new Iphone7 seems to have bluetooth problems in my car. Everything works but the sound drops sometimes (often) when I listen to music. I didnt have this issue wiyh my 6s and IOS10. I tried to reset everything but the problem persists. The iPhone is recognized by the radio inmy Toyota, but the sound drops just as it was a radio in a tunnel.
iPhone 7, iOS 10
I provided this to the techs weeks ago, but it seems like there was no headway. So here are the results of my trials for everyone to read:
I work in an environment where I have access to soundproof rooms. The walls are steel with padding and are about 6" thick (solid). These are "dead spots" for wireless in my building, which I surveyed and had to plan around because of the walls. I also work with deploying a lot of iOS devices, so most of my colleagues have an iPhone.
Testing environment:
I tested the area with an OptiView XG using AirMagnet Spectrum XT software. This device and software is used to measure the amount of Radio Frequency (RF) radiation in a given area to troubleshoot issues with wireless, and to help design wireless networks for large corporations. This helped me to ensure that there were no stray 2.4GHz interferers while testing, meaning that the only devices emitting 2.4GHz band RF were the "Devices" listed below (Beats Pill, Plantronics Backbeats, Braven BRV-1) and the phones.
Additionally, I tested the cars listed below in several environments with and without interferers nearby. These were less controlled, however mirrored the exact same results.
Stuttering/Skipping:
To show an example of the skipping sound that I am referring to, please take a look at this video: https://www.youtube.com/watch?v=kGHFDRVA958
Bluetooth devices tested:
iPhones tested:
As you can see, the issues are localized to the GSM models using the new Intel modems. This further solidifies the belief that there is an existing hardware issue and not a problem with software, interference, or other manufacturer's devices. I'm not sure what else I can do to troubleshoot with the Apple reps, but after spending upwards of $5000 with Apple in 2016, I can't help but to feel neglected.
I placed a call to the Lexus Technology Specialist for my local dealership and discussed the issue with him and how I troubleshooted it down to being specifically a Iphone 7/7+ issue when connected VIA bluetooth to the vehicle.
He acknowledged that although I was the first one to report the issue that he is aware of, they have been expecting this issue because Lexus vehicles, even up to 2016 are using the old bluetooth protocol and the iphone 7 is only using the new protocol. He stated he will start researching the issue, but updating the bluetooth protocol in the vehicle can not be done with a software update. It will require a hardware update which he suspects that Lexus will not do under warranty.
I will update this post when I get more info from him.
Same problems with my 3 cars in diff brands and models :
1. Sound volume is signi lower
2. Can't stream music
3. Keep dropping connecation
Same problem here 2015 BMW with Connected Drive system. Latest firmware.
Whatever new features are in the BT protocol that Apple is using in iPhone 7, it should be backwards compatible with previous BT, if working correctly.
Same here, 2011 Acura MDX, Pandora and Downcast both drop out regularly (have not tried others). Sometimes it reconnects as a speaker (no wireless signal displayed and can't accept/place calls) and other times it connects regularly. I have tried turning off Handoff and change the bluetooth setting from "automatic" to "headset" in the accessibility settings but nothing has helped. I had a iPhone 6s Plus on iOS10 with no issues but the iPhone 7 Plus is having this issue.
Issue is a bug caused by interference with GSM cellular signals. It goes away if airplane mode is enabled (plus turn back on bluetooth + wifi).
Submit a bug report to Apple: http://www.apple.com/feedback/iphone.html
Been having the same issue with the bluetooth audio dropping out in the car with the iPhone 7 plus. I just submitted a bug report to apple. Keeping my fingers crossed they fix it soon.
I have this problem too, 2012 Acura MDX. I made a call to the apple rep today and she actually told me this was the first time she had heard of this issue, after seeing this thread... obviously a huge lie. This issue needs to be resolved by apple ASAP before it festers into a iphone6 bending gate issue. I am very shocked at the fact that apple development engineers failed to realize the BT protocol is different from their advanced technology and most of their product users have cars fitted with the older technology and that they did not make it compatible. Shame on you apple!
Similar issue here in my 2013 Ford F-150. Says it connected then wont play, then drops the connection. Sometimes it will connect and play for the rest of that drive. But the next time I'm in the vehicle it will refuse to connect after several attempts.
Husband is also having issues in 2013 Lexus. Connection keeps dropping. I've noticed that it happens more when you're receiving notifications (text msgs, calendar notifications etc.).
As referenced below and here, airplane mode is a temporary solution if you must have Bluetooth music streaming.
Same issue here. I hope Apple sees this. How can we get it more visible?
Having issues with my Ford Sync along with my various blu-tooth headphones.
It's very frustrating. Listening and the audio drops out for a few moments.
I concur that the connection drops when your getting notifications, emails, etc or anything using cellular data... This morning when I started up my car I was still in the garage connected to WIFI from my house and music started streaming through bluetooth from itunes. As soon as pulled away from the house and the phone switched from WIFI to cellular data the audio started cutting out...
I don't think it is limited to cellular data though. Any GSM cellular signal (AT&T, T-Mobile) will interfere with the bluetooth connection. Cellular needs to be turned off completely for the BT connection to work properly.
