Unless it's priced reasonably I can't see doing this. IMO SYNC3 is fairly good. It's not bad at least. Certainly better than SYNC2, and possibly better than the Mylink in my old 1SS 1LE. If a SYNC4 upgrade costs 4 figures then I personally would pass.

 

Before going to sync 4 I'd aftermarket head unit with imaesrro kit. Cheaper better sound and newer hardware

 

This guys pretty knowledgeable on sync system he’s working on it

2019-2020 Ford F-150 Sync 3 to Sync 4 with Wireless Apple CarPlay™ and - Infotainment.com

It's available!

 

Over priced and you cannot get any updates.
You also have to ship them your old APIM as a core or you get charged even more.

 

Yes, I'd wait for someone else to pioneer it. I noticed that about the core as well. Having to mail them the old APIM is just a cash grab so they can sell those as part of over-priced Sync 3 conversion kits. No reason they need a Sync 3 core for this Sync 4 conversion that I can think of since they are not using Sync 3 APIM for the conversion.

BUT they are the first to offer it, so there is that...

 

Has anyone used infotainment to upgrade from MyFord touch sync 2 to sync 3? Is it reputable and was the upgrade worth it? Been thinking about upgrading my 2013 eco boost lariat but wasn’t sure if it was worth it.

 

I've upgraded Sync 2 to Sync 3 on a few 2015 F150s. I didn't think 2013 had Sync 2, I thought it was only an option on select Limited 2014 12 Gens.
If I were you, I would (and have) DYI. You could pay $1500 for a kit online or grab everything you need for a couple hundred bucks at a junk yard instead. It's up to you. The least expensive one I ever converted for someone cost $60 CAD

Saskatchewan is the only place in North America I know of where auto salvage yards are owned and operated by the government resulting in dirt cheap parts and auto insurance. It's a formula I wish the rest f the country would adopt, but that's another topic.

You'd also win off the exchange rate if you're in the USA so shop around on sites like SGI.
Come to think of it, I'm working in Regina in two weeks if you need eyes on the ground.
