A lot of pages and my head is spinning! Have a 2019 F150 and 2018 Expedition and the F150 has 3.4 in it - we love the look/feel. We would like to put it in the Expedition which is equipped with NAV. The Expedition currently has Sync 3.0 build 17276. My reading of a good chunk of this thread seems to indicate our Expedition will never update to 3.4 on its own (as it's not officially supported?) so I'm looking for some input/guidance on how to proceed. Just want to make sure I'm not missing any gotcha moments such as having to do the update in multiple version steps. TIA!
