This conversation is becoming a little bit "hot". I know this issue is annoying.
I will add my bit of information to the thread.
I'm a owner of a Seat Leon, 2020. MIB3 installed on Head Unit.
I started getting the "pixelation" only using Waze.
But not immediately, at the end of 2012, after a Waze update, while I was on iOS 15.
After 6 months, it started to pixelate even Google Maps, after an update (still iOS 15).
You can find other users in the same situation, here
I disabled the carplay intergration of both Apps, so at least I can use them on the phone, with driving directions on the speakers and having other (working) apps on Carplay Display.
Never experienced any issue with Apple Maps.
I upgraded to iOS 16, with no change.
But it seems that iOS 16 exacerbated the issues to a wider "audience".
Cabled or wireless, doesn't change the problem.
I'm a software engineer, with more than 20 years of experience on my shoulder. I think that @Desmoben1
partially got the point.
The problem is a combination of unlucky occurences.
Navigation Apps stream video from the phone to the carplay device.
On the Car Head Unit, there is probably a system-on-chip hardware, decoding video, that is not working very well with the new library introduced by Google in their Navigation Apps.
Do you noticed any other app having similar issues ? nope. Only Google Apps.
So, the point is that Google is probably not going to "rollback" the library, the user affected are less than users without issues (probably). It will be a risk to change the streaming library, for other car-makers.
Is Google interested solving an issue with an Apple Device ? So and so, probably they will tell you that Google Maps works best on Android.
Is Apple interested in solving the issue ? Yes, probably they can mitigate, but the issue begin with the Apps and end on the hardware video codec mounted on cars.
Is VW( or other car makers impacted units) interested solving the issue ?
Yes, but probably, they depends on the 3rd party system-on-chip maker and firmware of each MIB3 unit. Probably firmwares are differents from car to car.
This problem is quite hard to fix, probably only putting on the same table Google,Apple and Volkswagen could lead to a solution.
Meanwhile I almost stopped using Waze from Jan 2022.
I prefer to swap car brand, rather than switch to an Android Device, sorry Google.
