My Corsair is supposed to do the same thing but I haven't been able to get close enough to wifi to try it.
Hi Steve. Just to avoid confusion here: Your 2021 Corsair does not have SYNC 4 with OTA (Over The Air) update capability. It has SYNC 3.4, which does not have OTA capability.
In fact, even the 2022 Corsair is not yet equipped with SYNC 4.
SYNC 3.4 does not have OTA (Over The Air) update capability. It does have SYNC updates via WiFi update capability, if connected to a strong WiFi network signal. However, OTA and WiFi update capabilities are two very different things.
Good luck.
EDIT- Several of us were responding at the same time and providing the same information.
