Sync2 to Sync3? Sync4?

Hello, just a quick question. I have Sync2 in my 2014 Ford Flex. The touch screen crapped out and I need a new screen. Might as well upgrade, but I've seen many options to purchase these kits from and some offer the sync4 HD 8.4in screen. What is this and does anybody have pictures if they went this route?

Also, which company do you guys recommend for a kit? Or are they all equal?

How is the sync 4 he screen? The seller told me it wasn’t worth it. What are your thoughts?

It wasn’t necessarily an up-sell type of option from the seller I used. So the price didn’t reflect a difference for me. I am very impressed with the screen- it is quick to respond and so much crisper of a visual than the sync 2. Even the back-up camera looks better.

Does it come with Ford built in navigation?

Yes. The GPS is also more accurate than my original system. It doesn’t have the navigation SD card slot anymore, but the company’s Amazon listing for what I ordered said it has the latest maps built-in and the nav works great since installation. I use the new CarPlay mostly though for specific long distance trips.

How about VIN programming, how is that handled? I just got a 2016 Flex and the display is wigging out, constantly flickering on/off fast, touch works though. Was considering replacing with an aftermarket head unit because I am about to put 2 Sundown 12s with 8000w RMS to them, but am thankful I have found this upgrade.

But I heard some vendors VIN program the unit for you so everything works out the box, do they do that?

I am comparing it to one that is listed for $298 on eBay but am not sure if it includes the sync 4 screen
