Pixelated screen using Apple CarPlay

So, I partially solved the problem. I have VW Passat 2021 with infotainment soft version 0809. iphone 13 with iOS 16.2

I did update of infotainment system, but the problem is still existing.

The problem occurs when you use carplay and at the same time your phone is charged from car's usb slot.

I checked both usb slots and sveral lighting/usb-C cables.

Carplay is working properly (without blurring screen and delays) when You use Bluetooth connection only.

issue is due to the fact Waze and Google Maps in their last version are sending 60 Frame Per Seconds (60 FPS) via Carplay to the multimedia units. VW MIB3 is answering to the iPhone that it is able to support 60 FPS, but in reality it can only support 30 FPS... so after a few minutes the memory buffer is overloaded and can't follow... the solution is that VW should say to Carplay that it can only support 30 FPS

I have 100% working workaround for my 2021 Tiguan

When I start Google Maps navigation, I immediately zoom out once. Then the problem does not occur for me

HW:56

SW:0809

If i dont zoom out once, it happens in 4-5 mins right away

If you use USB cable the screen will not be affected. However need to make sure that it is not still using WiFi while connected via USB.

If you are connected via WiFi while plug in via USB, you will see a battery charging icon at the phone status at the top right/left (depending on where you are).

If it is connected via USB, you won't see a battery icon.

Tried the usb solution as I noticed it was on Wi-Fi before finding this thread..for me it worked for less than a minute..the 5g bar was on 3 bars also so it’s not a streaming issue,this is so frustrating,I was a golf mk8 which Vw are having back soon as they can’t fix the very dangerous problem it has of thinking I’m driving on the wrong side of road..ie lane assist pulls me to the wrong side only to perform an emergency stop and it thinks I’m undertaking on motorways etc..again applying the brakes…CarPlay was the only thing working right and now this🙄

I do noticed that using USB cable also will have this glitch while on Waze.

I had the experience twice in a single drive while connect via USB (with WiFi turned off).

So it is not related to WiFi direct display.

I had also run into this issue as everyone else.

Well I was digging around a bit. The issue only comes forward if the CarPlay screen is not using the old standard (800x480px (5:3) aspect ratio - see the image attached.)

The only thing I was not able to find out, if the issue is related to the amount of pixels or the aspect ratio.

The german car manufacturers are suffering from this because they started using the Wider ( 16:9 and or 8:3 ) configurations.

You might know that the carplay or android auto hardware in the headunits are tehcinally just like a screen. They display the image sent by the devices and returning the input from the car. The audio is Bluetooth.

It's still mind bending that it takes that long for the companies to figure out how to fix this.

When I switch Back to the car default app and return to carplay I get instantly the correct location on google maps only to start lagging again, so I keep switching in and out of carplay to update my location and keep it responsive

Try asking your dealer for a software update (you need to take your car to your dealer, no over-the-air update, at least for now). Users with a VW and Skoda (included me for Skoda) have solved this issue by updating the software, VW-related car companies and dealers are aware of the problem and have already released a fix.

My whole apple play becomes very slow when this pixilation starts. Yes you can rectify it for about 3-4 minutes , but if you’re in a town it can take ages for the system to become responsive and so you miss turnings. Im just not bothering to use Google Maps now , which is bad. I’m just using Waze or TomTom via apple Play and they both seem fine. Apple Maps often takes me to the wrong location so I’ve stopped using this too.

From what other users suggested in previous posts, it looks like VW released a software update that fixes the issue. Don't know, however, if it also depends on specific car models, other than the provided infotainment system

It appears no one. My car has been into Vw three times and they can’t fix it. So obviously it’s an Apple issue , but they don’t / won’t do anything.

I don’t have any issues in my Honda using it by USB. Just my VW on wireless

If it’s something on the headunit makers side then we can hope that they will be able to figure it out before the cars warranty expire. Last time my car was in the dealership’s repairshop for a 6 hour update cycle - they enabled wireless android auto since the unit was created without the function - they pushed a 30GB update to it, so we can forget OTA. The manufacturers gods help us, they will get there in time otherwise it will be broken forever…

Waze app flakes out on 2019 Honda Accord with iPhone14 Pro as well with latest updates, on both head unit and iPhone, never makes a difference. Did it with my old iPhone XR also with the latest updates.

There was a comment no that much ago ( 3 posts before by otters ) saying maybe headunit os version 1896 solves this issue.

The only issue with that is that last time I was the dealership they didn’t find any updates for headunit. so I don’t know what to tell them to find it :(
