Hello guys, i want to upgrade my Sync 3 to 3.4 for my Ford Fiesta mk7 2019 plus (no navs, just rear park assist, no camera).
Will my rear park assist continue to work after the upgrade? I cannot find anything related inside the forum. Is there any feature that will stop working?
Thanks!
That should continue to work as normal.
Make sure you do a master reset after the upgrade.
Personally when I do these I also pull the battery cable for 35 minutes as a second step after the master reset completes.
