I'm facing a problem that I'm no longer able to use Carplay and Android Auto. I'm using iPhone 15 Pro Max 17.0.2 since I first got it. I connected the phone to the car with the same USB C to A cable I have been using for 2-3 years. Initially it worked and able to get Carplay working for like 3 different days. But now it constantly says
"A charging error has occurred with the connect USB device. When safe please check the compatibility of the device and USB cable and try again"
whenever I connect the cable. It shows charging status for 5 seconds and than disconnects with the above message pop up and constantly on loop cycle while connected.
I can't recall those exact numbers but I'm confident that the phone has always been above 50% charge. Morning around 85%-95% and after work hours 50%-70%.Just speculation on what may have caused it to do this after several days of working fine, by chance was your phone fully (or nearly so) charged those first several days, but then at a lower percentage when it stopped working? Perhaps those first several days the phone was not trying to draw much power, but then, with a lower battery prompting a higher charge rate, tried to pull more power than the port allows. Not sure if that's how that process works.
If that's not the case, have you tried rebooting the head unit? I think if you hold the power button down for 5-10 seconds, it will ask you if you want to do so.
I read somewhere that the iPhone can fast-charge up to about 80% (so tries to draw more power?), then slows down beyond that. But it sounds like at least some of the times you've tried, it's been well above that.I can't recall those exact numbers but I'm confident that the phone has always been above 50% charge.

I have indeed restarted the head unit and even pulled out the fuse that powers the head unit (have done this in the past when screen was stuck at the welcome screen). However restarting the head unit does not solve the problem.
Other major concerning issue is that now Android Auto no longer works. Bare in mind that it has always been working using the one cable for 2-3 years only until using Carplay which cease to function.
So there is a new update 17.0.3 which seems to be addressing the heating issues that I don't have. But I just updated the iPhone and re-tried and same result.I read somewhere that the iPhone can fast-charge up to about 80% (so tries to draw more power?), then slows down beyond that.

I've tried several cables that I had on hand, with some of them working, and others doing the thing where it connects for a few seconds, disconnects, reconnects, disconnects, etc.
One possible explanation is that your cable that you've been using coincidentally stopped working (and the USB-A to C adapter you are trying with the other cables isn't cooperating with the iPhone's USB-C implementation, as a post on the previous page explained... "This is fundamentally a USB power delivery configuration issue that puts the phone into a Power delivery mode that the USB Host will not support. Cable's impact this because the USB-A to USB-C converters are not consistent.").
But a far more alarming possibility is, as you note, that the iPhone somehow damaged your head unit. I found a cable that works for my Honda, but now I'm hesitant to use it.
lol, blame the EU.🤣 So many iPhone 15 bugs and blunders.
I'm still holding out hope that there's another explanation, that the USB-A to USB-C cable you had been using with Android for 2-3 years and used fine with the iPhone for several days just happened to fail, AND that the configuration of the USB-A to USB-C adapter you are using when testing the USB-C cables is causing an issue.So to sum up all the info so far. The cable and adapter is definitely not faulty and is able to handshake together. The only thing I can think that is the potential problem for Carplay to not work is either:
-iPhone 15 Pro Max + software(17.0.3)
-Car's Faulty USB A port
2021 Jeep Wrangler with 15 Pro Max. The Jeep has both USB A and USB C ports to connect to on the dash. Since I got the Jeep, I have been using an Amazon Basics Lighting to USB-C red braided cable for CarPlay and it's worked great. I have a variety of USB-C to USB-C that I carry for my MacBook Pro and iPad mini in my backpack, so when I got the 15PM, I grabbed one of those and that's when the issues popped up.
After much testing, even with Apple's included cable, at least with my Jeep, I can conclusively say that orientation matters. Between the cables I own and a few I've bought for testing, it always matters which way you plug the cable into the phone and the Jeep. In some cases, it even matters which end of the cable is in the phone vs. the Jeep.
I also tested my Amazon Basics Lighting to USB-A cable. That also works, as long as you have the USB-C end to the phone in the correct orientation.
I ordered a few cable, including some Thunderbolt ones from various reputable and rated manufacturers off Amazon - brand names I've used in the past. Some worked, some didn't. Some cables seem to be charge only. When I think about it, I have a mini usb dock for my MacBook Pro, so I would have never noticed this in the past when hooking up to a TV or moving data.
With USB-C on both ends, there are only 8 combinations of ways to plug it in, so it's pretty easy to test. The included Apple cable is the easiest to use for now as I placed a little sharpie dot on the side that needs to be up on both ends. With the Apple cable, it doesn't matter which end is in the phone vs. the Jeep.
I have a couple more cables coming so we'll see how those test out. I need to get in a friend's car that is not a newer Jeep/Dodge/RAM (MOPAR) product and see how it works. I also need to get in a 2024 Jeep that has the latest Connect (it changed in 2024) I have two theories:
1. This is a MOPAR software/port issue on UConnect, maybe up to 2024 and maybe across the line. I won't know until I test. (I am leaning this way as the ports on the dash work fine, but ever since I got the Jeep, if I try to use the USB-A connection inside the arm rest, it is unreliable for CarPlay. It's been tested and replaced and still behaves the same).
2. This is an issue that Apple will fix in software (just a guess - haven't taken the time to read and understand why/how this could be a thing).
It is absolutely charging. I did remove the car from the phone's knowledge, but have yet to try the other. I will. I did try to get a USB-A (male) to USB-C (female) adapter and use it with the Apple provided USB-C cable, but no joy yet.In the head unit you can go in and tell it to forget the phone, likewise in the phone you can go in and tell it to forget the head unit.
Once you do that it will require you to repair and reactivate the next time it is connected.
Try that and see if it helps.
Also does it say it is charging? or does the power get disabled to the phone?
For those of you who have bought those wireless CarPlay adapters, how is the battery life? I want to get one, but they're not going to be very useful if they kill my battery life quickly.

Really? I’m going to have to look into that - where did you find out that info.So it seems Apple's USB-C to USB-C cable is the most reliable, which is good for newer cars with USB-C, but would require a dongle for USB-A.
Whatever you do, I strongly recommend against getting an adapter-style female USB-C to male USB-A solution, as they violate the USB standard and can be a fire hazard.
Update. Roommate came from home interstate. I tested carplay with iPhone 12 Pro Max using official Lightning to A cable and confirm the car's port is still functional and carplay works.I'm still holding out hope that there's another explanation, that the USB-A to USB-C cable you had been using with Android for 2-3 years and used fine with the iPhone for several days just happened to fail, AND that the configuration of the USB-A to USB-C adapter you are using when testing the USB-C cables is causing an issue.
See this post:
My layman's interpretation of that post is that some USB-A to USB-C cables and adapters are wired in such a way that the USB-C device erroneously believes more power is available than the USB-A port is able to supply, which causes the port to shut down when the device tries to draw that power.
You note that the cable/adapter combo works when plugged into a computer or USB hub, but could the reason for that be that those ports ARE able to supply the amount of power the device is requesting?
Maybe I'm grasping at straws, and admittedly I don't have enough knowledge about the technical details of the USB spec to know if that's a possible explanation. But other somewhat supporting bits of information are that the car's port is still working at least somewhat for data (since CarPlay does appear for a few seconds before the disconnect/reconnect cycle begins), and it is consistently supplying power (to the Android device with the original cable).
One other idea is to try that USB-A to USB-C cable (the one that's been working for several years) on the computer, to see if perhaps a data wire is broken (and just the charging wires are intact). If it's able to communicate (of course, making sure that you're not just seeing the iPhone via WiFi rather than the wired connection), that would indicate that it's actually not broken, and would largely disprove my hopeful theory. If it doesn't communicate, then that explains why even the Android is not able to connect to the car.
Glad to hear the port isn't fried. If you don't want to wait until December for the new cable to arrive but also don't want to play cable roulette, this one worked for me:Update.

All USB-A to USB-C adapters, regardless of the arrangement, are potentially a fire hazard.Really? I’m going to have to look into that - where did you find out that info.
Does it apply to female USB-A to male USB-C adapters too? An example.
I have a Logitech one for my mouse, and some Anker ones. Any idea as to where I can see what was recalled?All USB-A to USB-C adapters, regardless of the arrangement, are potentially a fire hazard.
The reason for this is that USB-C can carry very high current and/or voltage. The risk is true even for cable-based dongle and USB-C power adapters. Even brand names like Anker were recalled in the past for fire hazard. Hyper is another infamous example.
But the adapter form factor is particularly risky due to more compact form factor -- closer proximity to two devices transmitting electricity.
Both my Bugatti Cheron and McLaren 750s work fine.
