Pixelated screen using Apple CarPlay

SOLVED

I got my Golf to my dealer to get an update to version 1896 - took them a whole day! But now I can use google maps again without any issues!

Hi,

the issue is resolved in SW update 1896. It is for VW concern vehicles (Skoda, Seat, VW, ... ). You have to go to dealer as it is not over the air update.

Go and ask your dealer to update the SW.

VW software update is projected to be available in May 2023. Need version 840, is what I’ve been told. Will need to go to dealership to do.

Today I had a visit to SEAT authorised service, and they told me that pixelation is the common issue across VW group, and that is there when dark background theme is selected, there is a break in data transfer.

He told me that the solution is to remove screen timeout, to be never, meaning screen should be all the time on, then problem will not occur.

I did not tried that but if true, can help others. In the meantime my infotainment was updated, and lets see if it will work with the update....

Hi family,

I just wanted to update you all about this, because I did went through the customer support escalation, high enough to involve the developers into this.

By phone call (sorry I didn't record it), I got the verbal confirmation that the devs know about the problem very well. The customer support informed me that a software update that fixes it is on the way. I asked about when this would happen: the answer was a bit too much approximate, with a date around Jan 23, but that was it. I hope it happens earlier than that and not later. But ultimately, I just wanted to tell you to keep an eye on the updates and install them because one of those will fix this eventually.

In the meantime, I think I will use my old android to navigate.

I hope I helped a bit.

Finally had a reply from VW We Connect. Confirms future VW upgrade:

Thank you for your patience.

Kindly be informed that there will be a new software for your system which will fix the issue but is not available yet.

The actual plan is that it would be available in CW04/23 but this is not guaranteed.

Feel free to contact your workshop by that time and ask for software-version 840.

We sincerely apologize for any inconvenience this may be causing you and we thank you for your patience.

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.

1 jun 2023: pixelated screen-problem solved. My car : Octavia Combi iV (2021) / iPhone 13pro ios16.5 . Software update (nr 1896) by Skoda-dealer Tilburg- Bastiaansen (NL) solved the problem!! Waze en Google Maps working perfect with Apple CarPlay.

After a lot of trial and error and cardealer check on my VW Tiguan it seems finally resolved. Ive clean up space on my IPhone. Think Some free space is needed for data caching.

Same issue with iphone xs.

experienced on ios 15 and 16.

Seat Leon 2020 with MIB3 infotainment. Initially it was only Waze. Now it started with Google Maps. Apple Maps working fine. It seems that using those apps slow down the phone and the carplay screen start to slow down more and more. Only solution is to kill the appa from phone.

problem experienced both cabled or wireless. It seems that a google library mixed with infotainment video codec is causing the issue. Really don’t know where to bang my head.

I made some tests and I got the following results:

• Tiguan 2022 (MIB3) and Iphone 14 Pro (IOS 16.2 + Waze 4.90.0.1) --> screen pixelated
• Citroen C3 and Iphone 14 Pro (IOS 16.2 + Waze 4.90.0.1) --> no problem
• Tiguan 2022 (MIB3) and Iphone 6 (IOS 12.5.6 + Waze 4.78.3.0) --> no problem

So I think either Apple or VW can solve this problem...

Hi,

This workaround on Waze seems to be working for me since a couple of days:

• put your maps on 2D (no 3D, no automatic)
• Do not check "automatic zoom"
• Maps type: default

I got not pixelation since then, I'm feeling Waze a bit slower but still usable.

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

Yeah!! Finally got mine resolved. It was an update in the head unit firmware. I guess the squeaky wheel gets the most attention.

Thanks for the information. Otherwise; I might end up barking up the wrong tree.

"If you need help with CarPlay 

If CarPlay doesn't work like you expect, learn what to do.

First, make sure that your country or region supports CarPlay and that your car supports CarPlay. If you're unsure if your car supports CarPlay, contact the vehicle manufacturer.

Make sure that your iPhone has the latest version of iOS. If your iPhone is updated to the latest version of iOS, follow these steps — checking CarPlay after each step:

1. Check your connection to your CarPlay stereo:

• If you have a wired connection, try connecting again with a different USB cable to a different USB port if you have one.
• If you have a wireless connection, make sure that Wi-Fi and Bluetooth are enabled under Settings > Wi-Fi and Settings > Bluetooth.

1. If CarPlay doesn't activate automatically, look for the CarPlay logo on your car's display.
2. Restart your iPhone and your car. 
3. Make sure that Siri is on.
4. If your iPhone isn't detected by CarPlay, make sure that CarPlay isn't restricted. Go to Settings > Screen Time > Content & Privacy Restrictions, tap Allowed Apps and make sure that CarPlay is enabled.
5. Go to Settings > General > CarPlay, tap your car, then tap Forget This Car. Then set up CarPlay again.
6. Make sure that your CarPlay stereo is using the latest firmware from the car manufacturer. Check your car's manual for more information.

If you still have issues connecting to CarPlay, contact Apple Support."

We hope this helps.
