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

Exactamente igual; es una pena y muy molesto.

Mi Coche: Mercedes-Benz GLA 200 2019, he probado con cables y un adaptador inalámbrico.

Adaptadores: CPlay2Air

Teléfono 1: iPhone 17 Pro Max (iOS 26.1) → Fallos de CarPlay (con cable e inalámbrico). Ya cambie 2 cables y no mejora, por favor no compren cables para solucionarlo, es completamente ineficaz y no hay solución.

Teléfono 2: iPhone 15 Pro Max (iOS 26.1) → Funciona perfectamente, creo que debería volver a mi telefono antiguo.

Lo hubiera sabido no habría comprado el IPhone 17 Pro; sin embargo, varios familiares y amigos han conocido esta situación y han evitado comprar los nuevos Iphones porque prefieren tener su CarPlay funcionando correctamente, por lo menos hasta que haya sido solucionado este molesto bug.

No it’s not Merc fault it’s Apple !

we will have to wait for a new update to fix it like iPhone 15 did .

only issue with my 17 pro max

Final update from me on this. I gave in and handed back my beautiful 17promax and swapped for a 16. The 16 works perfectly on a 2017 an A class Mercedes - the 17 pixelated badly and was unusable for CarPlay. The 16 is a great phone and I just didn’t want to wait for a fix that may never arrive.

Same exact issue on a 2018 GLC300 with Iphone 17 Pro. Was previously using iPhone 13 Pro with IOS 26.0.1 and there was no issue. I am outside my return window so cannot even return this phone and go to a iPhone 16 like so many others have. Nothing has changed in the Mercedes - the only change is going from a 13 Pro to a 17 Pro so it looks like this is an issue with how the 17 Pro is sending video to the the car. A fix needs to come soon otherwise Carplay becomes useless.

It is an Apple issue. I was at the dealership for something different and they told me they have been fielding calls and walk-ins concerning this. They told me the same thing seems to always happen for the first month or two after the new iPhone comes out. Apple needs to come up with an update.

I have the same problem, iPhone 17 with iOS 26.0.1.

Mercedes A180d (2018).

With the iPhone 16 and iOS 26 I didn’t have any problems.

This issue started with the iPhone 17.

In my opinion, there are compatibility problems between Mercedes and the iPhone 17, because CarPlay works fine with my iPhone 17 in another car.

Same Issue with Iphone 17 Pro with my B class from 2018 W246 connected via wire but also wireless using a dongle. However using the same phone in my wife's Hyundai Kona no problems at all so it must be the combination Iphone 17 with Mercedes media centre.

I've been fighting Apple since iPhone 17 launch day. I have a Mercedes GLA 2018.

I opened a case with Apple, which asked me to toubleshoot by changing VPN, Wifi but nothing worked, and they then told me I was on my own. Therefore I opened a case with Fair Trade Australia, which forced Apple to try doing something.

On my own, I tried updating iOS, different cables, a bluetooth adapter, etc, but nothing helped. As a few people described, I tried to disable Wifi, but that also didn't help.

This morning (Nov-11 2025) I dropped my car off to Mercedes for a diagnostic as directed by Apple. Before accepting the service they contacted a technician who informed they are aware of the issue, and that plenty of people are having the same issue. They said the best they can do is to update the infotainment software, although I don't think that's covered by the diagnose service.

By the end of the day I'll have an update for you all.

Update: I tested my iPhone 17 Pro Max (iOS 26.1) with 2018 Audi Q5 (wired connection). No rendering issues. CarPlay works perfectly. Using the same phone and the wire with 2020 Mercedes-Benz SLC 43 AMG, the rendering issues have NOT been resolved.

What is happening to us owners of the new iPhone already happened with the iPhone 15 and with Mercedes. They fixed it with an iOS update. I hope they do the same again this year and fix it for the iPhone 17.

For now, the best way to go is to use Android AI boxes like Ottocast or GetPairr. Just a heads-up: the device needs to have an Android interface, not just a wireless carplay adapter—that’s the main thing. Basically, you’ll need to act like you’re using Android. For me the GetPairr Go 2.0 fixed the problem.

Problem occurs also with the iPhone 17 Air. First noticed this on my 2019 GLC 300 with my iPhone 17 Pro Max. So I tried my wife’s 17 air. Same problem. Switched multiple cables and adapters to no avail. Finally today went out with my older iPhone 16 Pro Max, and everything was fine. Apple has some work to do.

Same here on my Gla 2019 , even bought new apple lightening cable .

apple support blame the IOS update for iPhone 17 pro max

My Honda Goldwing has exact same problem. I found a workaround, if you use the split screen with GPS on left half then it seems fine so far. Otherwise on less than a minute it starts pixelating.

Ottocast play2video or Getpairr Go 2.0 will solve your problems, it’s sorted my Merc 2017 out!
