All the models are on a different schedule for Sync 4. The 22 Corsair still has Sync 3.4 but I use a cheap dongle inside the console that allows me to have wireless Apple CarPlay easily. Purchase off Amazon as there are many 3rd party vendors of these Airplay dongles. I have zero complaint about Sync 3.4. It works fine. The only advantage of Sync 4 is online updating and that has little value to me.
