Alles anzeigenmissrolan: "Touch and go" means with navigation. So you will get not only the DCU device but additionally the MEU module. I think you don´t need that, as it´s got only european maps.
For the european Corolla there are two different head-units (both Panasonic). The 2019 model was delivered with MM17, which does NOT support carplay or android auto. Since 2020 model it´s got the MM19 WITH carplay and android auto.
If your ebay device does not have CP/AA, it´s the MM17. Its model-ID is something like 17TDT1EU-DA01 (01 or 02 at the end, not 31 or 30).
This device can be upgraded to MM19 with the files on USB 3 (drives 1 and 2 are only for the versions with navigation / MEU). But in some cases as in yours the upgrade fails. In this case only the dealership could help be resetting the device to delivery status.
So maybe it could be an option to send it to Toyota Motors Europe or a dealer here. I don´t know if that is a useful hint for an ebay-customer in asia.
But if you like buying new head-units this could be interesting for you:

Some users of this board already have it in use as you can see here: Alternative Head Units
Or an android extension of the existing head-unit could do it: https://carperformance.se/prod…9-up-android-extension-2/
The easiest way should be to buy a MM19. But also the most expensive I think.
My unit was MM17.And I update it fails with USB 3.So I'm thinking if I got a Touch and go, maybe I can updated it successsfully.
