    Seems like the first update for the European on-board navigation is available.

    You might be able to find it via the "e-store" in your country's Toyota site, but you can also get it from the Toyota-Tech site at https://www.toyota-tech.eu/Navigation/base if you make a free login there.

    My July production car came with "2023-2024 Ver. 1" - the one currently on the site is 6 months newer (Ver. 2). And I think the next one should be due quite soon.

    You install via USB - need a 32GB FAT32 memory stick, as it's over 20GB of data.

    Updates are free for 7 years, as required by the EU speed limit regulations. To get the free update you need to enter some numbers from your navigation unit, the site generates a license code, and you type that into the car as you start the update.

    I haven't tried it yet - will be having a go tomorrow. Got my USB stick ready.

    And the update process worked. Not driven anywhere with it yet, but it's reporting the new version at least.

    Took maybe 40 minutes.

    Only troublesome part contrary to the documentation is that the update didn't actually start immediately - instead it said it was ready for update and going to start the update on the next power on. A few attempts to turn the car off and back on that looked like they were shutting down the multimedia system didn't make it proceed, but after a long press of the volume/power knob to reset the head unit, it started.

    I think your problem was that the head unit goes into standby mode after shutdown and stays that way for some number of minutes before shutting down completely. So what you were doing was switching the head unit in and out of standby, not actually restarting it.


    I suspect the reason for the standby period is to prevent errors from occurring if the car is restarted while the head unit is shutting down at the same time. It's basically a computer, after all. We all know modern computers take a few moments to close out all the software before powering down. And we also know that forcing a computer to restart in the middle of that process would be a bad idea. People don't think that way about cars yet(even though they're really a set of computers), so a car owner has no problem shutting a car off then immediately turning it back on again. By having the head unit go into standby at shutoff, it protects the system from a quick restart. But if the car stays turned off for maybe five minutes, the car knows that it's probably safe to start the full software shutdown without being interrupted during the process.
