Apple CarPlay issue with Toyota ProAce City (same as Peugeot Expert)

[Gnom]

Hi, first of all sorry for posting about a Toyota here but the Toyota ProAce City is actually a rebranded Peugeot Expert/Citroen Berlingo (even has the PSA logo on most parts)!

For the last few days, Apple CarPlay is not working correctly, sometimes it connects for a while when turning on the car, but most times nothing at all. This persists with several iPhones and several cables, which all work fine on another car, so I suspect this is an issue with the infotainment unit. I tried to reset to factory settings but that didn't help so I'm looking at options to try and get this working again.

I think maybe a more deep reset could exit, or possibly a software update or something, but it is very difficult to get help from Toyota due to the car being a Stellantis design that they don't seem to really know well.

I found this forum by searching for the versions I found on the unit, with mentions of Wave2, 3, 4 etc. but at this point I'm totally confused about what this all means ^^
Here are the different version numbers per the unit's System Information screen:
HMI version: rcc2021.82.21.14.01.00
iMX version: x0601042_211122_20.0H023
V850 version: RCC19_19.1S18.14

Hope something can be done to get this back, I rely quite heavily on it due to the lacking overall design of the dashboard/infotainment !

Have you tried an android phone and used the equivalent of car play whatever that is?

You have an Bosch RCC Wave 3 infotainment system.
That particular firmware version (0931, which you can see in the previous screen of that HMI/iMX/V850 versions information) was installed from the factory in some cars, but it was never released to the public. In that site, if you double-click in the "Version" of the table, you can see it was released on 23 Nov 2021 and that there are some recent versions.

Toyota has a site - https://www.toyota-tech.eu/ - that helps you updating those systems, but that seems a problem with the USB socket.

Thanks for your help!

I also thought about a usb socket issue but I tested a usb drive with music on it and it worked. It doesn't entirely rule out some weird/intermittent issue of course but it at least suggests the issue might be software. I'll see if I'm able to do something with those resources.

Also, I was able to open engineering mode using instructions in other topics (hold media button for 6 seconds), but was stuck at the PIN stage. Is the PIN common to all vehicles of a specific model? Is there anything that could help me in this maintenance mode?

For the RCC, the code is 7503900

What you call the media button (could you post the picture)?
