So my Edge is at the dealer for a buggy Sync. The 2020 Edge loaner I am driving has a buttery smooth transmission (1471 miles). It feels like a CVT for real. I mentioned this to the service advisor and he informed me that they flashed a TSB for mine. Let's see how it is when I pick it up.

I have a 2019 Edge SE with the basic 4" sync and no subwoofer (6 speaker system). As I'm deaf, I'd like to add some more bass to the driver's seat area. So I was looking at an under seat subwoofer. How would I go about adding one of these (perhaps a MTX TN8MS) to the stock Sync system? I haven't done any head unit/subwoofers/amps since my 1995 Jeep Cherokee, which was a heck of a lot simpler.

Yeah. I only tried the Cyanlab version because the official update from Ford "broke" my Sync. Even after a new APIM, it still does the same thing. And I've tried to look everywhere online for the 3.3 file, but can't seem to locate it at all as it was included OEM for the 2019 Edge. I can find files for the older version of the 4" sync, but I don't want to risk running that on mine. I have a feeling the hardware is different, which is why there are different file versions (EG: Older 4.6 vs Newer 3.4.20136). The only place I know that has 3.3 is Cyanlabs, but as you saw in my picture, that doesn't work as it's made for the 8" screen. As of right now, I'm just gonna have to deal with it and wait until an opportune time to have the dealer run their "diagnostics" on it.

The thing is that they work specifically with the 8" Sync3. I'm using the 4" Sync with MyFord (non touch). I did send them a message to see if they can provide the download link for the 3.3 (4"). It's dumb that both the 8" and 4" Sync get the exact same file version named Sync3 Version 3.4.20136. I tried using Cyan's version and that produced interesting results.

Update 2: picked up my Edge and all was well until I got home. Sync is doing the exact same thing, even with a new APIM. I'm about ready to just get a new head unit but don't want to lose my Sync functions.

Update : Even though the update for my Sync was an official one from Ford, the dealer said that I need a new APIM. I've heard of this happening over the years. You'd think that Ford would be able to fix this without having to replace the APIM. I sure miss my Edge, and will be without it for a few days. At least I get to play with the Sync3 3.4 in the 2020 Escape loaner I have. I'm surprised at how peppy that 1.5L Inline 3 is.

I updated to Sync 3.4 on my 4.2" Sync with My Ford. It seems to be a little buggy. Whenever I start the car, it defaults to the radio screen (but the radio is not on), when engine is powered off and before the door is opened it will switch between day and night mode randomly, when turning off the radio it will flash the screen with the previous one several times before settling in the clock screen. Wonder if anyone has the old update file for 3.3 that I can try to downgrade to? Remember, this is not for the 8" Sync 3. I've done the reset, etc etc and was wondering if someone had the file so I can try downgrading before having to take off work to go to the dealership.

OK. Another update here: Using the Cyanlabs sync update does not work with the 4.2" screen at all!! It did install the 8" touch screen version and the results were... interesting. I couldn't do anything on the Sync. Fortunately I had the Ford website version saved, so I installed that again. Screen now went blank, radio volume worked, and reverse camera worked. That's it. The only way I could get it working again was to pull Fuse 33 for the Radio under the footwell. And now it's back to the same initial glitchy mess. I just flashed it again with a new USB drive and let's see what happens. I may have the dealer check it out regardless, just in case that blank screen wasn't just a fluke.

Update : Updated Sync twice and still the same thing. Trying the Cyanlabs version now, as it does say that it works with the small screen. If that doesn't work, I'm going to try to downgrade using the Cyanlabs.

Did another master reset and same thing. Gonna try updating again after a master reset. Sorry for the short video but it's the only way I could attach it. 20201012_071037.mp4

Does anyone know what fuse to pull on a 2019 to reset the Sync? I upgraded to the 3.4 version on my 4.2" and it has a weird glitch where sometimes I start the car and it is stuck on the radio screen. The volume controls don't work. I can press anything else (as if the radio was on). I have to turn the radio on and then off to get to the clock screen. Also after turning off the radio, the screen will go to the clock and glitch the radio screen briefly. As in glitch, I mean it will flash the radio screen a split second after the clock screen comes on. I've tried a master reset, pulling fuse 32, and a hard reboot (power and seek up) with no change. I think I pulled the wrong fuse. The radio presets stay there, which indicates that it hasn't been truly reset. After a hard reboot, the radio works fine until the car is turned off and it goes right back to being "glitchy".

Perfect answer. That clarifies so much!!! Never knew there was a Sync 3 lite.

That's what I'm using and that's why I'm asking here. Here's a screenshot. That's why Im asking if it is designed to work with the 4.2" screen? My 4.2" screen says it has SYNC3 3.3.### right now.

So it still would use the Sync3 3.4 update? right now it says I have the SYNC3 3.3.#### firmware.

I have the base 4" version. When I put in my VIN on Ford's site, it says sync 3.4 update is available. Not sure if there's a separate update or if the 3.4 file works with mine too? Mine says it currently has the sync 3.3 on it. Odd...
