OK, I know this is probably stupid but have you double checked all of you VIN letters and numbers? For example o’s and 0’s I did this once years ago and it drove me nuts until I finally figured it out.I'd love to go thru the steps for my 2021 Mach 1 but the Ford map site says "invalid VIN" so I can't get the update. (Sync 3 is updated.) Multiple calls to Ford CRC have not resolved the issue. I welcome any suggestions from someone with experience or connections to Ford.
