I'm afraid that update is not available in Europe... and I doubt it will be in a near or far future.
Despite the European version of the Camry is equivalent to the one sold in other markets, these guys decided that no updates will be released. If you check the radio&navigation software, you'll be amazed to find that our systems are running "Touch2Go" and not "Entune". Yep, a completely different system despite the interface looks the same.
Options you (and me) have are:
1) Install an aftermarket box that connects to the car screen. This will result into having 2 systems, and you have to switch between them using the screen buttons to use the carplay unit.
2) Install a aftermarket radio unit. Expensive, and probably we'll loose some features.
3) Best one, but absolutely not desirable for obvious reasons you'll find further, is a company that offers flashing the unit to bring Carplay available.
Bad new is that you have to dissasemble the radio and ship it to... Moscow. They have a 2nd location were to ship the units... Kiev.
Before Russia decided to invade Ukraine, I had been in conversations with these guys as interlocutor of a Camry Spanish owners club. Price is around 300€ plus shipping costs but, honestly, despite my contact seemed to be a fair and honest person, after all this mess began, we decided not to proceed.
