Upgrade Ford Sync 3 to 3.4! 

WOW!! That worked great! I put the drive in and it told me that I needed to reload the thumb drive and try again. I pulled the drive out and it said "Put the thumb drive back to proceed" so I put it back in and 30 minutes later it rebooted and worked perfectly. Nothing in life is ever this easy but it appears that the planets were aligned and I can't be more happy. I'm so glad I got this used car! Thank you so much!!!

It took 49 minutes on my focus mk3, so if anyone is reading, do not worry :D

Thank you so much for making this video. You couldn't have made a better video it went exactly as you described.

downloading as we speak for my 17 F-150 on 3.0

I normally do this without the vehicle running by turning the key to the on position and back to aux every once in a while so it doesn't completely turn off, and doesn't use much battery or any fuel.

spot on

I upgraded my sync 3.4.20237 to 3.4.23188 (canada) and have lastest version in truck. When going online and logging into account it still shows previous version and multiple calls with Ford customer suppport to no avail. They seem to refuse to updates, even though I sent screenshots and log file, they say its a dev issue. Sync 3 says real time traffic updates, thats a lie it does not do that and Ford apparently has no plans to change it.

Will this work on a Mac computer???, Wanted to give you guys an update!! I was able to install the 3.4 updates, and it definitely works better! No lag time, better options and all! I’m loving the new look along with the options

Why would you want to upgrade to this sync version? What so much better about it? I just updated my 2017 truck to version 3.0

Hi, your video helped my upgrade. Thank you. How ever I don’t have a volume indicator in my screen. Volume works but indicator is gone both knob and steering button. I did some research and found someone who fixed it but I don’t know how to do what they did. He daube did the following: consp wrote: ↑ You enabled Smart DSP which you apparently do not have. Set it to off. This option is the same for all versions (and Sync 2 as well I thought). In your case: set the first block of 7D0-01-01 to 086A, you enabled it by making the first byte 88 instead of 08. The DTC will also stop if you disable it as it no longer tries to detect the DSP and get the volume signals from it. The non working buttons: The configuration for both the buttons and steering wheel look correct. I do not know how the buttons on a mondeo are connected but if one of them works they should all work (depending of course on correctly configured software e.g. the dsp setting).

After my update to 3.4 in my 2017 MKZ, I lost all the SiriusXm logos. Did you notice that as well? Do you know if there is a Fix for it?

My install mode might be the issue but it doesn’t work, it’s stuck in reformat install mode as I’m watching yours and everyone else is in auto install mode

Good video. I have a question, please. do you have any idea how to add the camera icon (to activate or desactivate the camera) in the sync home screen ? (at the top right next to home icon ). what is the line or lines of code to modify (with Forscan). THANKS

Followed all of the instructions and boom no more sync 3. Gets stuck on a file that errors out. I tried several different version and always there are files that won’t load. 😢😢 Now I have to go to Ford… wonder what that’s going to cost😳

Hello, I am needing some help. I have an 18 mustang with nav version 3.0. I followed all your steps but when I hit "start" and it's supposed to download to the USB drive (it's a USB 2.0 32GB) it does it in less than 5 seconds unlike your video and every other videos I've watched. My internet is NOT that fast. I plug in my car and all it does is reboots...i checked the memory on the USB and I still have 29GB or so which makes me think it is not being downloaded to my USB.

Hi You don't say that you cant do this to a my20 apim which you would find on a year 2020 ford and later. If you do this on a my20 apim you will brick your unit.

Great video, very easy to follow along! Looking to do this upgrade soon!! Quick question, do you know how to add the "Climate" button to the main screen? Since I see some Navigators have the climate button on the main screen and some do not, thank you!

I have a sync 3 that has no touch input everything shows on the screen as it should. I was told to reinstall the or upgrade software first before buying a new screen. Its a 17 Focus St. I have no way to get to current version number etc. Can I still try this by using any current version number and going to 3.4 ? I was going to choice the lowest to make sure nothing is missed

Good job

I just downloaded this on my computer but now when I open the application it tells me there’s an error not found. Any way you could help me?

Thanks for the video. I want to try this, but I don't have the cable to link from my computer to sync. Can the updates for forscan be used on a jump drive to change the screen size?

I switched from Sunc2 to sync3 and the build is 19200. It's currently 23188, so should I just go with what you told me? My car is 2016 explorer

Is this still working. There’s a newer build it says to use. Is that ok?

Just curios why the vehicle needs to be running? Battery life? My truck has 2 batteries and I am going to run my Snap-on Charger on Flash Mode which is made for doing this exact sort of thing So I was wondering if there was any other special reason to have it running

Does it make it where it are not so slow?

Hey I know this video is a little old but I have a question, in your video after the update I saw you did a master reset of the system, when you do this reset the system still keeps the update you just installed? It doesn’t revert back to the previous sync version before the upload via usb? Thanks for your time.

Hi bro I have ford and Mazda i need cheng language Arabic gps map I have forscan ids fdrs but not have idia how to chenge map language

In my 19 Navigator it just says updating system software, rebooting then it just reboots back to the Navigator logo

Will this work 2016 F150 with Version 1.0 It is Sync 3 Don’t want to ruin Thanks

Hi, i have sync3, ver 2.3, will this upgrade work on my vehicle?

What if your vehicle does not have navigation? Will this add it?

Can I downgrade from 3.4 to 3.3? After updating I have some issues with radio and bluetooth. How can I do it? Is there any tutorial?

does doing this change the loading screen when you turn the car on? i want to keep the mustang one on my car

Will this work on a 2015 ford explorer?

When I plug in USB, my truck immediately says “USB storage device has been changed or removed. Will resume when reinserted.” …. But it’s still plugged in. Everything else works when plugged in like Apple car play etc? Soooo??

Can I drive around while the update is downloading from the flash drive?

Bonjour, J'ai un Ford Ranger T7 de 2018 avec Sync 3 version 3.0 Révision 20204 Gracenote: 1.1.1.1127 (EU-0010) Version de carte F6.1 J'ai sur le site Ford une mise à jour des cartes à faire, j'ai donc préparé ma clé USB correctement. J'obtient une erreur LST_err05 lorsque j'essais d'installer la mise à jour. Ford en garage n'y arrive pas non plus. Je suis tenté de passé par votre programme, mais étant en anglais j'hésite à me lancer. Pouvez vous m'aider svp

Ive not done this yet but have the usb drive ready did you have the usb hib not supported issue?

I’m looking into getting 2016 navigator. It’s year model with interior update including sync 3. Does that mean I can update this system , and use Android Auto?

Hello there, do you think this would work on my mkz 2017 ?

What program did you use to change the screen size?

Hello, thank you for the video! I’ve updated to 3.4 perfectly and was just attempting to resize the screen using Forscan w the OBDlinkEX and ran into an error saying “I need an extended license to run this function”. Any help/guidance would be greatly appreciated! Thanks!

Can you drive around while updating to prevent the car/truck from shutting down?

Robot?

do you have the spreadsheet link for the Lincoln Navigator as built data?

Talk too FAST!!!

Can you change screen size without forscan?
