iPhone 7 with iOS 11 cannot connect for USB playback Hyundai Elantra

Thanks so much for posting this. I was running into dead ends with both Hyundai and Apple (each wanting to point to the other as the source of the problem) and this did the trick. I simply closed the Music app on my iPhone 8 before making the connection to my 2013 Sonata and the on-screen controls worked fine as a result. By the way, I'm using the "old" 30 pin Hyundai wire with a white Apple "Lightning to 30 pin" adapter.

Thanks again!

I face the same with my Accent (here in India its by name verna). This issue persists since first developer beta of iOS11. I reported it a couple of times but no gain.

Anyhow, I have a trick to make it work till the time apples fixes it.

When your car radio says: "Loading Error" or something similar, open any other music app on your iPhone (I open wync music here) and just play any music from it. Then, load the ipod by moving to AUX option from the radio. It will load and play that music. Now, on phone move to Apple music app and play. It will work. And all the other controls will also work.

This trick is useful as you don't need to restart the phone and also the music will start from the point you paused it last time. Otherwise after restart, it mostly starts from default first track.

Hope this trick helps some of you.

Actually, Hyundai's information sheets for the older cars, like 2012-2015, will say they do not support the USB-lightning cables, and if you order Hyundai's iPod cable, it is a 30-pin. Getting them to work with the lightning cable has always been a hit or miss, so your having it work was lucky. I have a 2012 Sonata that still has the remote cable that plugs into the USB and a remote plug for controls. That one is a 30-pin, and I used an Apple adapter with it, and it will work when it wants to. My daughter's 2013 Elantra does the same thing, and she has plugged hers in with just the USB and it seems to work more times than not with her iPhone. My wife's 2017 just has a USB connector, but it also has Apple's CarPlay and that one has not experienced any problems. You might also want to check with Hyundai dealer to see if your vehicle has a software update. I've done that to my 2012, and it seems to work much better now, although most of the time if I don't wish to listen to the car's radio, I will stream my music from my iPhone via Bluetooth.

No navigation. I use the phone itself for that (Apple Maps), though when connected via USB it reduces music volume and gives its audio directions via the car stereo.

Did a little more fiddling with it this morning. It looks like the trick to make it work is to force-kill the Music app (double-home then swipe it away). The next time I try to connect after doing that it works, if not, Loading Error. So at least that's more convenient than a full power cycle, which I had thought was the necessary prerequisite.

I wouldn't count on Hyundai fixing this. For one, they probably didn't even know there was an issue until iOS11 came out so even if they jumped on it right away, how long before they have a fix included in a software revision? As you noted, they don't even officially support lightning cable, so if I accept an update I run the risk of losing existing functionality! A risk I'm not willing to take.

And to me, if this worked in iOSes 7-8-9-10 and broke at 11 with the connected device unchanged, that tells me that Apple mucked with the USB interface to legacy devices, which leads me to believe they made a change they didn't expect to be negatively impactful for anyone, and if enough people report issues with formerly working docks they'll correct whatever USB-interface change is breaking things for people (that's why I'm here - adding another voice to 'the new iOS broke a formerly working car dock connection' tally). I have far more faith in Apple fixing this than Hyundai.

Bluetooth play on this radio ( https://i.ytimg.com/vi/sZDsV3A4Lb8/hqdefault.jpg ) was *never* interactive for me on any device - music devices connected via USB showed track-artist-album-time information on that little monochrome screen and one could choose tracks/albums/artists/playlists via the dials and buttons, and could skip tracks with the in-wheel controls... but if a music device was connected via bluetooth the screen only showed "MP3 playback" and just played whatever audio the phone was feeding it with no car interface for track control (of course, since handsfree siri went to "Wake up on 'Hey Siri'" track skipping/restarting became, at least, doable in a moving car without touching the phone).

I am having the same issue with my Hyundai Accent GL (2013). Most of the time if I connect, it shows Loading iPod then Loading Error. I’ve only ever been able to get it to work, temporarily, by restarting my phone. Which is awfully inconvenient. If I don’t restart my phone immediately before driving it won’t connect to my stereo via USB like it did just fine in iOS 10.

I also have a 2013 Accent GL with the stock stereo (no nav) and an iPhone 6. Thanks so much for the suggestion to force-quit the music app. So far that seems to be working. Here's hoping an iOS update resolves the issue.

My phone seems to work fine more (but not all) of the time in my wife's 2012 Tucson with the nav package, and she says she has zero problems with her iPhone 7 Plus, so it does not appear to be a Hyundai-wide issue...

Yeah, I use the official apple 30 pin to lightning adapter too. Worked flawlessly on my iPhones 5 and 7 up to iOS 10, just broke with 11. I can use Bluetooth too, but I lose in- dash track skip capability, which I use a lot, and is less stressful than yelling at Siri when I want to skip a track. :)

Strange you say that, as I've never lost any control of the device while in Bluetooth. Again, lucky you got it to work flawlessly, but that is on Hyundai. Good luck seeing if there is an update for your vehicle.

Another question, do you have Navigation? If so, those updates can be purchased and installed yourself if you wish, and don't have to go through the dealer. It updates your navigation maps, etc., and will also update any other radio software as well.

I'm having this exact issue, i have a 2011 hyundai sonata SE with the NAV. im using a gen 6 ipod connecting with the 30 pin hyundai connector, before the iOS 11 it worked fine (sometimes a little glitchy but never a big deal). now i cant even change songs without it saying it doesnt recognize the device and disconnecting it, and its moving very slow on top of that. i tried to revert back to an older iOS but apple wont allow that. they definitely need to fix this asap.

Thank you!! This has been driving me crazy! Annoying to have to start Pandora to get Apple music to play, but this works on my '13 Elantra. I figured this was an iOS 11 issue, as I've never had a problem in 4 years prior using USB - I even use 3rd party lightning cables w/out problems. I was having to resort to BT which gives no on dash info. Restarting my phone worked, but I had to do it every time. Well, that's a whole new level of annoying when playing a 13 hour playlist on shuffle. I'll admit to being disappointed in Apple. I love to goad my Android friends that my device just works. I guess the exception proves the rule? Anyway, thankful to be up and running again, so thank you!

i have this, and a related issue -- plugging in my iphone 7 (ios 11.2) to my elantra, and attempting to play via aux, the music/podcast will come out of the iphone speaker itself. i have to manually switch the audio output on my phone to the dock connector or bluetooth.

never had this issue pre ios11

my car synch doesnt work either
