I've had my car over a year now but have never received any updates at all. I have checked on the media but it says 'up to date'. I'm beginning to think the OTA update isn't working. It's 16 months now without anything, seems unlikely? Cheers.
The Gen 5 Prius is not a software-defined vehicle (SDV). Any OTA update is only for its multimedia system, and don’t expect many, if any at all. The new Gen 6 RAV4 is partly an SDV.
As long as OTA stands for Only Talked About I think it's working. After all, it's not like they named the company TOYOTA after such a feature.
