Just updated to Sync 3.4 on my Ranger 2019

So firmware doesn't need to be touched, just the map updates?

Correct. Map update only needs re-install.

When you put the Map USB back in the 'Updating System Software' message will appear so just leave that run to completion.

OK, this time it took an hour or so, 3 reboots later, all ok except had to do a master reset. The voice command flashed and ignored me. Had that happen in the Ranger too and also had to do a master reset. Now for sure, all is well. Thanks guys. What sucked was the fact that the system was not smart enough to just install the files needed. Wouldn't taken an hour if it could do that. No worry. Hopefully good for awhile...

You're not the only one who got fooled by the on screen messages during the map update. You basically have to leave the USB stick in until a message appears that says changes take effect after an ignition cycle (or some such verbiage). That message will not go away until it's dismissed and the sync system does not automatically reboot itself. Only then is it safe to remove the USB drive.

My OBD Link for FORscan shows up today. So do I actually need to change the three items in climate, or just climate domain?

Just climate domain.

Just climate domain.

Thanks!

After using the 3.4 for a couple of weeks now, the only real issue I'm encountering is that CarPlay is kind of like buying a lottery ticket. You never know what you're going to get.

I would guess about 20% of the time it doesn't launch.

A user on here (can't remember who but Thank You!) told me how to do a complete power off of the Sync system and that usually kick starts it to working.

If anyone else is experiencing this, to do a full restart hold down the Audio Power button and Media FF button at the same time for a few seconds.

Sync will reboot.

UofMEngineer... assuming that the fix for climate control and anything else that ails the current 3.4 update, in your opinion, how difficult would it be for Ford to correct the issues via WiFi?

Here is another confirmation that enabling the "Climate Domain" in the APIM Module brings the climate screen back to the display.
Also, I do not notice any difference in the quality of the on screen image from my back up camera. Everything else seems to work as before the update.
Thank you to UofMEngineer and the other members with some great input.

Just Climate Domain in the APIM Module and not the APIM (As Built)?

Are all the problems happening with 3.4 dealing with systems with nav or is it also for those without nav? I don't have the nav system and I'm really hesitant to download and install the updated version.
TIA

It's definitely affecting non-nav vehicles as well.

Assuming some fix is put into the core software, it'd just follow the normal process. OTA is usually released after USB as it needs to hit X number of test cars before it's switched on. As far as when any fix would make it into the software totally depends on the usual items, like schedule, program sign offs, etc. Short term, if they've supplied dealers with a fix that may be the fastest route.

Check earlier in the thread for the link to the motorcraft as built site. You can check there if you're impacted.
