Pixelated Apple CarPlay screen on iPhone 17 Pro Max with Mercedes BClass W246

Have spoken at length to apple and they don’t care, are aware, won’t be doing anything ..I was advised to wait for iOS 26.4.. no change… they know but as they have my money they don’t care. Don’t fall for “ buy a new cable” or “ try ottocast” waste of money but I won’t be buying an apple product again

Thanks for that info, Flymo40….. well…. If they did not take you seriously maybe more of us should call so they can see how prevalent this problem is. While this discussion is focused on the Mercedes brand, it is happening in both of the 2021 Hondas I own. And I’ve experienced this in rental cars. You say you “have spoken” to Apple - can you share the phone number and extension you used so that other’s may call?

iOS 26.4.2 does not solve the problem.

I downloaded the latest OS this morning and tested Apple CarPlay this afternoon on my Mercedes A250 (W176) without success. My old iPhone 8+ worked flawlessly on iOS15.8.

Maybe If I could have both phones registered under oner account with my mobile account provider I could use the old one for Waze and the new one for all else :) I know - not possible without a new number and $$$$.

I tried using Apple Maps. It has exactly the same problem

Very frustrating

Looks like it’s been fixed for me in iOS 26.5.2 on iPhone 17 Pro and Mercedes GLC. So on the one hand it took ages but on the other hand if Apple support ever read these forums thanks for fixing it 👍

I even bought a wireless adapter to see if it was wired related but the same issue is there.

Had no problems with a 16 Pro Max and a 15 Pro Max, both on iOS26.

My new iPhone 17 pro ios26.0.1 has same issue with A200 W176, the CarPlay was working very well with the old iPhone 13 upgraded to iOS26.0.1, so sad. Hope Apple takes action on the issue soon.

Mercedes GLE 500e 2016 - NTG5.1 - usb A - iPhone 17 pro 26.1 - issues

Mercedes CLS 450 2019 - NTG5.5 - usb A - same phone iPhone 17 pro 26.1 - no issues

Got this on eBay as suggested by another user on this thread. Item 365307304835

Still waiting for an iOS update… beyond a joke

I have the same car as you and upgraded my phone from 13 to 17 Pro and am experiencing the same pixelation problem. So are we waiting for another software fix from Apple?

So what changed between your successful and unsuccessful trips? Connection method, car OTA update, apps used, starting car before/after connection, etc.

If both Apple and Mercedes are blaming each other for this issue then what are the options?

CarPlay gets used extensively by my wife during commutes and it's unusable at the moment.

Surely it's worth Apple engineers looking into and if it's unfixable as it's an inherent side effect of the iPhone 17 series hardware then make a statement to say so.

How many people are trying multiple things or buying items in the hopes of finding the remedy. I myself have bought new leads and a wireless adapter to try to sort the problem to no avail.

I'm a long time happy Apple customer with many, many Apple devices over the years and when something like this happens I usually have faith in Apple fixing the bug in a timely manner. Not optimistic if they are saying it's down to Mercedes to sort, which let's face it.......will be unlikely. Even if by some miracle they did, you know they'd charge a massive fee to update the car's software.

Feels hopeless. 😞

It’s incredibly frustrating that this is happening with my iPhone 17 Pro Max in my Mercedes A180d. I can barely use navigation without frequently exiting CarPlay. Apple needs to fix this issue with the next iOS update.

Same issue with Mercedes Benz GLA 2017 - Wired and with wireless adapter. I called Apple they restored my phone and no luck. Issue still happening they advised me to speak with Mercedes which I haven’t as out of warranty. Please advise me if there is solution

Same issue here. Recently purchased the iPhone 17 and now having this fuzzy connection issues when using a USB to connect to my CarPlay on my A Class.

Wasn’t an issue on my iPhone 12. Used over 5 different cables and the issues persistent.

Have to resort to using the small display. Apple need to fix ASAP.
