Hi,
I have a 2017 MKZ Hybrid. Fully loaded. I have been interested in upgrading the sync 3.0 to 3.4.
(Yes, I know it will have to be "unofficial") I've heard a lot of people saying it "couldn't be done" but I ran across this guy who did exactly that with his 2017 MKC. [ https://www.mkcforum.com/threads/unofficial-update-to-sync3-v3-4-for-those-interested.30334/ ]
Do you think this would work with the MKZ?
I'd really like to make this happen for the esthetic differences and the couple extra features.
Thanks in advance for your insight.
