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

Here we go again….Upgraded to iPhone 17Pro Max and apple carplay seems to have an issue. This seems to be a recurring issue when the new iPhone and new IOS comes out. When i connect directly with the cable in my Mercedes BClass W246 the screen blurs and pixelates like the picture below. I have tried removing the device from the car and car play and yet the issue persists. This makes apple car play unusable with without constantly exiting the app and going back in, to which the screen refreshes and works for less that a minute. The apple side bar continues to be blurred. This happened when the apple 16 came out and 13. My previous iPhone 16pro did the same until and update from apple. Same as the iphone 13pro previously. Any assistance would be greatly received…

Following advice from others I purchased this new - Ottocast TV Mate- from eBay UK, for £37. Plug the ottocast unit into the CarPlay USB A port in the car and connect once using WiFi. IPhone connects to CarPlay seamlessly and is wireless. Amazing and very easy. All functions work. HMDI

port not needed. This is only

required if you want to mirror an app from

your iPhone but does not provide CarPlay functionality. Thanks all.

Yet all iPhones before the 17 series with iOS26 work fine. If the problem arose with the 17 series, then that is where the problem lies.

Apple knows the hardware differences these new iPhones have and can therefore fix this with an update.


If it's physically impossible then they need to announce it to prevent customers from buying new cables/adapters or paying for car diagnostics which would be futile.


I know many people would have maybe not purchased a 17 series iPhone knowing of this issue and it will definitely put off prospective buyers with the effected Mercedes vehicles if they knew.

Hi,


So I’ve had a bit more of a play with the device today and got it working far slicker to the point that it’s a very happy compromise.


Once you have done the initial set up, which is difficult with the controller (you can’t use the remote) but it can be done then it boots to an android screen, easy then to ask it to go to CarPlay (it’s all prettty fast!)


You can use the Mercedes controller in the android screens, I can get iptv/prime video working etc but the issue comes when a keyboard is needed, hence why you can’t set WiFi without a remote or add passwords to the apps, no WiFi no updates either.


the UI in my opinion in the android screen, which will also Bluetooth music looks better than the Mercedes one in my opinion.


I paid £40 for the getpairr variant from AliExpress and I’m really pleased with the solution! Probably a better outcome than apple fixing it.


ive also reported to the manufacturer the issues regarding set up without a touchscreen and the fact that you can only have one BT device operational once (so you can’t connect the phone and a remote at the same time) along with a request for it to boot straight to CarPlay rather than the android screens….they ar every helpful and have requested the amendments for future updates.

Just think about that for a minute you are thinking of selling your car because Apple new device has a problem. It would surely be cheaper to change the phone. The iPhone 16 works perfectly with all version of the Mercedes.

I still have my iPhone 15 and have gone back to using that temporarily. You can get the iPhone 17 to work but only in split screen mode as soon as you change to full screen maps it will Pixelate .

Apple has been trying to convince Car manufacturers to let them take over more of the Car display functionality. Fortunately most if not car manufacturers have turned them down.

New update from Apple after they’ve already loaded my phone with the car play diagnostic profile and being advised this works fine with other models of iPhone:


“From our engineering team: 


Thanks for your patience here. AppleCare Engineering have advised the issue here is coming from the vehicle. They suggest utilizing reseting the Head Unit as the short term work around.


For further assistance on this they recommend the customer work with Mercedes. Assistance may come in the from of additional troubleshooting, configuration, stereo firmware updates, factory resets, service, or documentation about this.


Hope this helps”


it does not help…Has anyone got any firm evidence from Mercedes that can be sent across to the engineering team at Apple?
