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

Thank you for sharing the information. Unfortunately, the workaround provided by Apple doesn't solve the problem for other car brands and even high-end motorcycles. I don't know what major change was made to the iPhone 17 Pro, but if I had known about this limitation beforehand, I would NEVER have bought the smartphone.

I have the same issue of a pixelated maps screen. Gla 250 2018 when using a IPhone 17 air. It doesn’t matter if the connection is wire or wireless the problem is the same.

IPhone 14, 12 and X all work fine, the problem only relates to the air.

Apple do I really need to use my old X to navigate…Please confirm when you will do the update to fix the issue.

Hi,

Did you buy the remote? That really helps as it’s the only way you can use the keyboard or anything that pops up on the screen (without it you can’t do updates either or connect to WiFi) if you don’t have a remote the Alcontrol app can do the same thing.

Bear in mind you cannot have your phone and remote connected at the same time so set everything up with the remote first, (including g app passwords) on startup it’s really hard to see but you can just about make out to set the time/location/language etc (you must complete this process 3 screens I think or it comes on everytime) 

Once it’s all setup and updated, unpair the remote and connect the phone. To use the remote again you have to unpair the phone (very annoying but I have brought it to their attention).

Once you finally get it set up, took me ages and like you very frustrating and had to show a lot of patience, it just starts up and CarPlay works (you have to click on the CarPlay app icon with the joystick).

It’s worth the effort!! Trust me…..the distortion drove me insane, daily!!! 

I had no idea about a remote. I will look into that app you mentioned instead.

EDIT: Looking and I'm not seeing that in the App Store. Could it be another name? Also I have looked for the remote and it's not available on Amazon.

Same thing here. Many CarPlay issues. Screen breaking up. I disconnect and reconnect - sometimes it’s fine and sometimes it’s distorted. Other issues - music sometimes resumes, Siri decides when to work and when not to work, Bluetooth devices don’t swap between phone and other Mac products like my iPhone 13 Pro Max and buds pro… text messages are read sometimes and others not. Basically my old phone was 10 times more reliable than the new one.

when you own an expensive car and an expensive phone… you kinda expect them to work - I love some aspects of the new phone, but mostly it seems full of issues. Hopefully an update comes soon. Otherwise I may have to just return this and go back a generation. Seems like those of you on 16 have had none of these issues.

We re having a similar issue with an A Class W176. Both 17 Pro Max and Air not working correctly with the pixelation.

Same as me, Mercedes A Class.

I have the same problem with my GLC. Was using the iPhone 14 Pro Max and I had no issue at all. The pixelation appears after I've upgraded to 17 Pro Max. **** disappointed and frustrated.

I have the same problem. I had no problems with my iphone 13 pro and ios26 and upgraded to 17 pro and now it is happening, I don't know how to fix it

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.

Same here with my CLA250. Worked fine with my Iphone 14 pro, the moment I upgraded it stopped.

@Apple plz fix

did you ever remedy this issue as I am currently facing this problem and unable to find a fix
