Hello so I am trying upgrade my 4” screen to an 8” screen. Could an 8” screen from a 2017 mustang work with a 2019 mustang? And if so what would I need or is it plug and play?

Check out this thread:

Upgrade Factory 4” sync to 8”

Yes, the screens are the same. It's not exactly plug and play. You will need a special harness to 'translate' the wiring from the 4 inch connector to the 8 inch connector. There are a few vendors that sell them, like Hextall Harnesses. You're going to also need to do some programming in Forscan to change up some feature settings. Give the thread a peruse, and feel free to come back with more specific questions.

19's at least didn't require a special harness for the conversion - it was plug and play for me, going from the base radio to a sync3 kit from HHP. Same for the digital dash, which was a nice surprise.

What is HHP? Is that aftermarket? My assumption from the OP's post was that they were wanting to go to the OEM 8 inch. It's quite possible that aftermarket vendors sell full conversion kits with Android infotainment systems, that don't require the harness. But from what I understood, the APIM for Sync3 has a different connector on the back than the APIM for Sync1, so that's why you need the conversion harness. Basically, its going to bridge your car's Sync1 wiring into the Sync3 connector on the back of the APIM. Again, I'm sure aftermarket vendor's built this into their solutions, but for OEM to OEM upgrade, its a necessity.

HellHorse Performance, Gator.. Full kit, no harness included as the entire install used the factory wiring - unplugged the old components and plugged in the refurb'd ones, with again.. NO harness.

What you might be forgetting about is that the 2018's and above already come with the USB hub that the sync3 apims need.

I did not know that. But again, I'm not sure that that's the entire story. Again, most certainly, the Sync1 APIM connector on the back is different on the Sync3 APIM connector. So if you're car was a 2015-17 and 'non-premium' it came with an OEM wiring plug that would plug into the Sync1 BUT NOT the Sync3 APIM. Hence, the harness. So that leaves us only with 2 possibilities:

1) Ford started manufacturing Sync1 APIM's after 2018 that had the thicker Sync3 connection. That would lead to a plug and play solution, as you state.
2) Or the Sync3 APIM provided by HHP had some sort of adapter on the back. If the USB connection is already accounted for, it would simply be an adapter that would take it from (guessing) 24 pins, to 16.

Did you do it yourself? Are you saying that your car's Sync1 OEM wiring plug, plugged right into the back of the Sync3APIM? There was no superficial adapter on it? If so, this kinda throws me for a loop, but that wouldn't be the first time. That could only lead me to believe that they Ford changed the Sync1 APIM, slightly, after 2018....which is a possibility that I never investigated.

Lastly, as I stated in my post on the thread I linked, all these 'full encompassing' kits are quite the pretty penny. I piece-mealed everything myself, and it came out to about half of the price of the HHP kit.

Here's my sync1 from the back, still attached to the old 4" screen. Looks the same as the sync 3's 2019 and up on ebay, in any case. I believe either 2018 or 2019 and up, and a new sync3 apim will go right in. What I see as interesting is if you put one of these side by side, then aside from the extra USB connector (which I believe WAS depecated in the latest sync3 apims) you have to wonder what the physical difference is inside.. I heard more memory / flash on the sync3's but I don't yet have the guts to go find a few to tear them apart, let alone the $$$'s..

As far as the rest of your replies (if I did it myself, more to the story?, etc ).. look carefully at the background with the hp analyzer, soldering station, and associated "tron geek" hardware and ask me again if you need to, LOL. Been doing this stuff for hell.. 30+ years. Let me know if you want an old vintage amp rebuilt, a TV repaired, or whatever's cost effective nowadays... (wink)

Would I do it all over again? Maybe not...

I didn't mean to offend by asking if you did it yourself. Just trying to hash out the nuances in my mind.

That being said...that is not the Sync1 APIM. I BELIEVE that's either the Sync2 APIM or the MyFordTouch APIM. The OG Sync1 APIM looks like this:

38338


I just checked a part number spreadhsheet that I used when I did my change to see if I can verify which module it is...however, it was a manually compiled spreadsheet, by @blade007 , that really only accounts for Sync3 APIM part numbers, but he does have a small list of Sync2 APIMs on it. I could not find your part number on it. He kept the tally of the Sync2 APIMs because they look exactly like the Sync3 APIMs so you're not fooled when you try and buy one off of eBay and it turns out not to be Sync3.

Maybe @blade007 will chime in, since what I learned, I learned from him.

All that being said, my thoughts are that the 2018's and up 4 inch screens were outfitted with the Sync2 APIM. My guess is, since there was no software version release of "Sync2" that the change in "Sync2" was the USB hub support being built in. So in the end, you are right. If you have a 2018+ 4 inch OEM radio, you DON'T NEED the harness....since the OEM wiring will plug right in to the Sync3 APIM also...since the sockets are the same.

Thoroughly enjoyed hashing this out. Thank you.

Hey Gator, no sweat and no offense taken LOL. I'm with you.. trying to figure all this out ever since I bought the 2019 in May of that year, new. I swapped and switched to sync3 just a few months later, since as far as what Ford offers stock it left a heck of a lot to be desired. On BOTH the radio and dash, I did a lot of research that ended up me scratching my head, looking at what I had versus the many pics and videos I reviewed to get an idea of how to do it.

LOL I also didn't mind rooting in the closet for all the old stock hardware in any case, as I also have a "sales query" out on a manual GT base Kona Blue "up the road". Been contemplating "the dark side" a little, and wondering if one angle is to keep the dash and sync kits to reinstall. Sync would likely be a no brainer. Dash not so much as it's already been set and overall the Eco's pushing 40K on the odometer. I'd have to get the dash corrected.. hmmmm... I think I'll stay away from "The Dark Side", for now.. (y):cool:

If anyone is looking to upgrade to sync 3 on their cars check out midway mustang and wade motor sport on ebay
I have purchased from them in the past and they have complete kits for about $550 or so. This is comparable to searching on car-parts.com
The 18+ cars should be a direct swap and the 15-17 cars will need a harness to complete the install
Hope it helps someone
