I just set up my wifi. It says I am up to date. where do you find what version you are on for Synch 4. I did not see it .I have a 2022 Platinum Max and so far getting updates and no problems. Sync updated to 4.2.2 yesterday. I park in the garage and get updates at night over WI-Fi.
never mind. Just found it. It says version 22277, revision 588.
