ios 11 will not connect to car stereo with usb or bluetooth.

Yeah, but I figured I’d give it a shot anyway. Looks like it’s Bluetooth or a new radio. Supports Bluetooth for phone so hope it does for audio as well. Have to test it later. If not, it’s time to replace the radio - which is annoying not as much because of the cost of the radio as much as they can’t reuse the old hardware. So I need new interface units and they need to run a new mic. don’t understand why they just cant replace the iPhone interface unit.

Sorry, wrong. In 2011 the iPhone 4s was released. The interfaces in cars in 2011 were designed to connect and communicate via the IAP protocol (what you call the media interface) which was used by both the iPod and iPhone. The iPhone had a 30-pin connector up through the iPhone 4s. Starting with the iPhone 5 it came with a Lightning connector. So a car from 2011 was plenty capable of connecting to an iPhone via the IAP protocol.

You cannot make your determination of compatibility with his car based on the connector or the fact it was manufactured in 2011. If you have some valid technical information to support your absolutist statement of incompatibility and Apple's "evolution" please provide it. Otherwise do some more research. Starting with iOS11 the IAP/IAP2 and External Accessory Framework has been seriously broken, especially the EAF. This is affecting multiple manufacturers of external accessories (including my car's head unit, which is brand new).

The interface in your car was intended to connect to an old style (non iOS) iPod, not an iPhone. In the past, the media interface in iOS was 'close enough' that it worked in many vehicles.

iOS has continued to evolve, however and it no longer works in many vehicles.

There's nothing Apple can do about it.

Disagree - There is an interface standard in existence supported by Apple for some time now. It was broken in iOS10 for a while, then fixed. Seems Apple has broken it again in iOS11. I suspect Apple will fix eventually, but it perhaps not a priority. Either that, or Apple should officially report they have dropped support (seems unlikely at this point).

My interface still works intermittently on my 2012 MINI JCW - probably 50% success rate with a MINI 30-pin cable and an Apple 30-pin to lightning connector.

Still suggest everyone that has issues to open a ticket/case with Apple, or use the bug/feature request form on their website.

I would disagree, it worked, Apple made the alteration, it no longer works. The stereo is a static piece of equipment, the iOS is constantly changing. Many customers will buy a different brand of phone if the one they own is no longer doing what they require it to do.

No one cares if you switch to a different phone. Just know that Android users experience the exact same thing with updates. Just read their support communities. The only way to make sure it doesn’t happen is to not update.

Apple will care if they lose clients. The underlying problem is based on an Apple software update. This isn't the place for an argument, or product partisanship. We're looking for solutions, not smug answers

I have a similar issue. I have an iPhone 7 and it has worked great with my ‘16 Subaru WRX up until the 11.3.1 iOS update. Now when I try to connect to the stereo via Bluetooth or cable, it will only play the music/playlist I already had playing before I got in the car. Pressing the playlist button on the car usually returns a ‘No Audio File’ message, so I can’t change what’s playing. Every once in a while the playlist will show up, but they are completely scrambled and sometimes empty, so that *****. I’ve tried plugging it in, re-pairing, power cycling, etc. Sometimes it works, but every time I get in the car is a crapshoot. I took it to the dealer and they couldn't figure it out, either, but they also said I wasn’t the only one having issues -- the most recent iOS update was causing other customers issues to. So now I just have to be 100% sure my phone is already playing what I want to listen to in the car before I go anywhere. Very frustratin.

It unfortunately is apples prob because I do it drive a Kia I drive a Buick and the pairing was always working until it wasn’t. I have paired 7 different phones to my car via Bluetooth and they all worked just fine. But my iPhone 7 Plus still does not!!

I have a 2010 Hyundai Elantra Touring that requires me to use a special Hyundai adapter that plugs into the AUX and USB port at the same time in order to connect my phone to the cars radio and charge at the same time otherwise it acts as if I keep connecting and disconnecting the phone even while being connected at all times. My music played perfectly fine through my car once I plugged it in using a 30 pin to lighting adapter connected to the special Hyundai connector that’s made with a 30 pin connection. The music would automatically start playing once plugged in. Ever since iOS 11, I constantly get a “Loading Error” message which is super frustrating. Sometimes if I just keep clicking the AUX/iPod button on my radio, I can get the music to start playing perfectly fine. Sometimes I can never get it to work one day and then get it to work on the first try the next day. Completely frustrating.

The interface in your car was designed to be used with an iPod, not an iPhone. Earlier versions of iOS were close enough that they were able to be used. Later versions, not so much. Use bluetooth instead.

My vehicle is not equipped with Bluetooth. And the fact that I can get it to work sometimes and others I can’t tells me it’s not my radio. It worked perfectly fine with iOS 10. They should’ve kept the interface the same. An iPhone should also be considered an iPod but not vice versa. Also, the brand new Hyundai’s still say “iPod” next to the USB port and those are much newer and fancier radios than mine and came out after the iPhone X.

In all seriousness, if you haven’t done so already, try the latest iOS upgrade and replacing the stupid 30 pin adapter. I have the exact same situation on my 2010 Nissan Cube (down to the customized adapter port and the iPod on the radio). I haven’t seen those warnings in a while. I’m in the same boat.. IMHO it’s stupid to throw money at an old car to replace the factory radio and fix this one problem that shouldn’t happen in the first place... plus the installers where I live want to pull all of the existing components like the built in car mic and steering wheel controls and replace them. It’s a $700 job for a $150 radio. Insane.

If it’s new, then I’d suggest that’s probably not related. I’m at 11.4 as well. I’m just retracing what I did with my radio in the past few months where the problems seemed to have vanished, although I do get the occasional high pitched hum and problems with turning on the phone if it’s already plugged in and I have to stop the car and restart it to get it to sync. These interfaces are really touchy. Best of luck.

I have an I phone x. I have tried multiple usb cords including the cord that came with the device. I know they are connected bc it does work with an android. I’ve tried both usb outlets. I have power cycled, and hard reset the iPhone. Also thought maybe it would be my case and removed that as well and the iPhone X still argues that it is unsupporte

Lately I’ve gotten slightly better success if I have the phone connected via lightning port, shutting the phone off and then turning it back on and the vehicle sometimes picks it up. And yes, I know it’s not the radio because Android works perfectly fine on it. Including new androids. I purchased the iPhone X thinking that maybe my iPhone 7 wasn’t powerful enough with the newest iOS version and thought that since the iPhone X is so much more powerful, that it shouldn’t have a problem. Boy was I wrong.
