This past week I traded my 16 Edge for 18 Explorer with Sync 3. It has 3.0, v17276 installed. According to Ford Owner site, it was uploaded with this file JR3T-14G381-AJ Date Confirmed:Dec 19, 2017. Now the site is telling me there is an update JR3T-14G381-AL SYNC3 v3.0, which by the way, is trying to update via wifi on a daily basis, but errors out saying it can't download the file. I downloaded to PC and transferred to my trusty thumb drive. Take to SUV and it goes through the routine, but I get the "You already have the latest update" message. I'm perplexed. I suppose I should leave well enough alone? Thanks.
