Hi Trevor! I ended up postponing my upgrade since the car's AC is still under warranty and I don't wanna void it. I'll wait it out and perform the upgrade next year. From what I've researched, however, is that you will need an automatic temperature HVAC control module so that you can have...

Okay, 4dTech people said this: "Because of the required bezel changes the HVAC module also needs to be replaced to work properly.". I think you can reprogram the FCIM for it to work with the manual climate control module. I've asked some wire harness guys called Bestycar if they know anything...

Alright, I'll follow your advice and post any updates here.

Okay, that means that so far, the auto temperature control might be a must... Guess we gotta wait and see if someone says otherwise.

Was the car equipped with automatic temperature control before you switched it over to the sync 3 system?

I think you misunderstood me there. The FCIM (or radio bezel as I mentioned above) is what is used to house the screen and the AC controls. The HVAC control module is a black plastic box with 2 or so ports, placed under the ACM.

Agreed, it's very expensive. I've managed to find all the parts individually on eBay and Amazon for about 1000 bucks including shipping. I just want to confirm whether the HVAC control module is necessary or not, because it's very limited in terms of stock and is the most expensive part on my...

Yes, please. It would be great if you can link it here so that everyone can see it. Thanks a lot.

Hello, I'm looking to swap my Sync1 4.2in system with a Sync3 8in touchscreen system in my dad's 2017 Base Explorer. So far, I understand that I need those parts: - Sync3 APIM - 8in touchscreen - 8in radio bezel - 4 to 8 wiring harness - New USB hub and its wires However, some people that...

Just edited my response to show that, my bad. I just thought mguy13sport would appreciate a faster answer.

I know you asked Green94 but I've had a look at this throughout my research recently. The Sync 2 APIM isn't the same as the Sync 3's. You'll have to get a Sync 3 one if you're planning on upgrading. No idea about the reprogramming, as the parts and configuration needed for the 4" to 8" swap is...

Old brackets as in the 4in Sync1 ones, or replacement Sync3 ones? I'm guessing you're talking about the Sync2 ones.

Thanks, Peter. I've been seeing you all around the forum and was wondering when you'd show up :)

Hey guys, Apologies if this was posted before, the forum search showed nothing that helps. I have a 2017 Explorer, base trim with the 4-inch sync 1 system. I'm intending on upgrading it to sync 3 very soon. I've tracked all the parts down and all's going well. However, the local scrapyards...
