Sync 3.4 Upgrade 2017 F-150 Lariat Questions

If I update to 3.4 do all voice commands still work or is that another file to be installed?

When you reformat to 3.4, all files are replaced with the 3.4 versions.

Ok cool, so just to confirm that the only things that may not work is ford pass and grace notes? But can be reprogrammed to do so? Thanks for all the help, your very knowledgeable on this

Just FordPass, GN will work.

Ok and then last question is my heated steering wheel, will I need to re ad that through forscan?

It should stay, but if not it’s an easy add with FORScan. Take a look at the Asbuilt Database on the site in the Ford Hub section.
