Iphone 11 Pro Max and Carplay not working

Found a solution here. Please buy a USB male to type c female converter. Use that to connect with the type c lightening cable comes with the iPhone 11. It works immediately when I plug in.

It is the software and hardware compatibility issue. This could be a fix before the official solution comes out.

EUREKA! HOW TO FIX IT. This full-charge strategy doesn’t work for me, but I think I can explain why it works for you.

It works for the same reason that using the original-type-C-to-lightning cable that comes in the box with iPhone 11 Pro Max works for me, and has been working without fail for 15 starts and 3 days now.

Ladies and Gentlemen, it’s all about BANDWIDTH. I submit that the new “intelligent” charging algorithm that Apple has developed for the iPhone 11 Pro Max consumes more bandwidth than previous phones. And of course, CarPlay consumes a lot of bandwidth between our cars and our iPhones.

I’ve been doing some experimenting with different cables. I have found that the new ANKER Type-C-to-Lightning cables ALSO make CarPlay work, when connected to my Mercedes with a generic Type-C-to-Type-A adapter. EVERY TIME, without fail..

WHY? Well, perhaps the Lightning-to-Type-C-cables have a different chip that provides more bandwidth than their Lightning-to-type-A predecessors. This enables them to transmit CarPlay data PLUS additional power that may be needed to charge the larger iPhone 11 Pro Max batteries using the new battery optimization algorithm

I don’t know if this is true, but it seems reasonable, and the proof is in the pudding. Just get yourself an Apple OR Anker Lightning-to-Type-C cable, and attach a type-C-to-type-A adapter, and I’m betting your CarPlay woes will be over.

Similarly, if you give your phone a 100% charge prior to connecting for CarPlay, then your cable won’t need to charge your phone, and you MAY have enough bandwidth to boot CarPlay with your old Cable.

Finally, whenever Apple gets around to fixing this flaw in its new charging algorithm, CarPlay will probably work,with our old cables.

P.S. This bandwidth theory would also explain why cars that provide WIRELESS CarPlay have no trouble with the iPhone 11 Pro Max —because they don’t need to rely on Lightning cables of any type to transmit their data,

I have been experimenting with cables, and it looks like the iPhone 11 Pro Max needs MORE BANDWIDTH in order to support CarPlay PLUS Apple’s new battery optimization algorithm. The old USB-Type-A-to-Lightning cables don’t have enough bandwidth to transmit all the data you need for CarPlay while also transmitting the power needed by your iPhone 11 Pro Max.

SOLUTION. Use an Apple-Authorized, USB-Type-C-to-Lightning cable, and attach a generic Type-C-to-Type-A adapter. I’ve been using both Apple’s own cable that comes in the box with my 11 Pro Max — and today I also tried the Anker Type-C-to-Lightning Cable. Both successfully boot CarPlay for my 11 Pro Max, 100% of the time,

HYPOTHESIS. I figure these newer, Type-C-to-Lightning cables have a newer chip that transmits more bandwidth. They were originally used to fast-charge and transmit data to the new iPads Pro (the ones with Type C connections), and they must have a wider gate for this task. Thus enables them to transmit all the data needed for CarPlay while also charging the iPhone 11 Type C.

Eventually, Apple can solve this with a software, and I understand iOS 13.2 does just that.

I FOUND THE SOLUTION ! CarPlay doesn’t show up in settings -> general if Siri isn’t on.

to unable Siri go to : Settings -> Siri and search -> Press side button for siri

and then it should work!

problem solved: go buy a new lightning cable from Apple directly the chip inside to Cable might be updated

I have the same issue here I recently purchased iPhone promax and it’s very lacking or not working on my aftermarket Apple CarPlay device. I have tried a lot of ways for example reset the iPhone or reset the Apple CarPlay in the car. None of them worked

but last night when I purchase a new pair of AirPods 2, I noticed there is a new lightning cable inside the box so I think about it why not try this new cable to the Apple CarPlay the cable might be the issue, and it worked curse out the lagging and no wood issue is due to the lightning cable. I have a been using the original Apple lightning cable in the CarPlay format iPhone XS Max and that it has no issue but it won’t work with Apple 11 Pro Max I do not know the reason, The result is just a go buy a new lightning cable from Apple directly the chip inside the cable might be updated in the works with iPhone 11 Pro Max and Apple CarPlay perfectly

first of all, my problem solved, with a new lighting cable from AirPods 2 box, 11 pro max works flawlessly with CarPlay now.

Please see below are my answer:

1) 11 pro max running 13.2 and 13.2.2 and 13.3, all of them are not working with CarPlay with old lighting cable

2) I just have my 11 pro max for 1 week, before this, I have my XS MAX, and works flawless with CarPlay

3) my Apple CarPlay is after market, never been upgraded. and to my best knowledge, Apple CarPlay device is just mirroring the iOS system, like a TV receive signal through HDMI cable from a XBOX. Therefore, there’s no need to upgrade your CarPlay device

just go buy a new lighting cable, try it, then let me know how this works for you.

Thanks!

CAR PLAY FIXED!

I have been so frustrated with car play since I upgraded to the iPhone 11 Pro Max. Kept thinking with every update that the problem would be fixed. My iPhone 10 worked great.

NOTE: I worked with a guy at my Apple Store & he gave me a new lightning cable right off the wall & since I plugged it in to my car I have had no trouble with car play. I had tried several old cords & they did not work. There must be something different with the newer cords. I was lucky to have been given a new cord but would have been so worth the $19 plus tax to have this issue fixed. Try it! You have 14 days to return the cable if it doesn’t work. Hope this helps!

I found a fix that might work for some people go to settings, screen time, content and privacy restrictions, allowed apps and then enable car play. I don’t use screen time but it was turned off for me so hopefully it will work for you too

Hey all, so in my case, I finally swapped my 6 foot long MFI certified cable for a 6 inch long one instead, and the problem has disappeared.

I noticed a genuine Apple cable that came with the phone worked vs. my 6 foot MFI one, so decided to just buy a different shorter one.

This was with a Nissan Leaf. Hope this data point helps some others in here.

OK GOOD CHRISTMAS NEWS TO ALL - Here's the solution to most peoples iPhone 11 Pro CarPlay Issues:

Use the Lightning to USB-C cable that came with your iphone. This phone does not work with the older Apple cables from previous models of iPhones with CarPlay.

You will also need to purchase a USB-A (male) to USB-C (female) adaptor, which will plug into your cars USB socket.

I purchased 'Joyshare USB 3.0 Male (USB-A) to USB 3.1 Type C (USB-C) Female Connector Converter Adapter for USB Type-C Devices - Black - Pack of 2' for £6.99. Note: I already has these adaptors to use with a MacBook Pro - so Im sure there's nothing special about this brand.

Note: I have a 2018 Nissan Leaf and had all sorts of problems before using the cable that came with the iPhone. Finally I can relax and enjoy using CarPlay!

I am in iOS 13.3.1 beta, issue still exist.

but I found the solution: USB C female to USB male converter, then use the original USB C to lifting cable coming with the iPhone 11 Pro Max, it works

USB C Female to USB Male Adapter (2-Pack), QianLink Type C to USB A Adapter, Compatible with Laptops, Power Banks, Chargers, and More Devices with Standard USB A Ports (Gray) https://www.amazon.com/dp/B07S617LN1/ref=cm_sw_r_cp_api_i_eDrcEbB81AMP4

I fixed mine today! I had Siri deactivated on the side switch turned off because I became annoyed with it coming up on my lock screen often when I grabbed my phone. Siri must be enabled for CarPlay to work on my 2017. Went to settings: general: Siri and turned it back in and CarPlay started working perfectly!

I had been hesitant to buy the short cable (6") cause it just didn't make sense to me that this would be the solution (at least for now) when I have a perfectly new apple 3 foot usb cord that "should" work. However, I bit the bullet and while I was perusing around BestBuy I bumped into the "Insignia 6" USB to Lightning" cable. I am on IOs 13.3.1 and it has been two weeks now and it Apple CarPlay works! no issues what so ever. Biggest downside is that you can't bring your phone close to you if you wanted to look at something (which you shouldn't while driving I know I know); but other than that, this has solve my apple car play issue. I've tried using the "regular" apple cord after making it work with this one and nothing, plug the short cable and voila! it works, it is the dumbest thing, but hey this one works out. I've attached a picture of the box from bestbuy and the link to it.

I grabbed a female USB-C to USB-A adapter and used the usb-c lightning cable that came with iPhone 11 Pro per an earlier suggestion. So far 100% success. Here’s to hoping it lasts.

From Engineers:

Hello Jeremiah

I just got a alert on my end, stating that the update to 13.1.2 SHOULD fix the issue that you’re having with your iPhone 11 Pro Max

As such, when you have the time, do a iTunes backup of your iPhone (just in case), and use iTunes to do the 13.1.2 update, and respond back to me if it fixes the CarPlay issue, please.
