2012 Explorer NAV updates?

Can you get updates for the NAV system flash card? Can you get them free?
Thanks.

Officially no, you'd buy a new card with the newer version which IIRC is around $150. There are cheaper avenues out there to get a new version on a card, which may be legit or may be something someone copied and hacked.

Hacked means there is a key file on the card that has a generated code based on the serial # of the SD card, which the Myford app uses to validate the license. Someone could put the files on, generate a new key valid for new card, and make their own.

People have posted links to some of the newer Nav files but I don't know where they are right now. I mean posted on the internet, I have not seen any links in this forum.

Thank you again for the great information. I don't need to spend the money for an update. Ford gave one free about 3 years ago and I was hoping I could get another update. But it is what it is i guess.

Some other random info I've read is that if you go newer than an A6 card (US, you did not mention your location) then you may have map lag unless you update to the Sync2 3.10 firmware, as the last before it (v3.8 aka 3.08) is reported to have trouble with the A7 and later nav updates).

I've also read that the A7, maybe even older than that, may need an SD card using exFAT filesystem instead of FAT32 because there's a file on it that's over 4GB in size.

I haven't done this myself, might think about it if I could find the A7 or newer US Nav update but since mine didn't come with Nav from the factory, it's a more drawn out process for me to write new build data to it to make it think it has NAV... or something about switching a wallpaper PNG file and telling it you have NAV when you do that....

Seems fairly complex for what people describe as only a so-so NAV system, now I'm more inclined to just use a phone with Google Maps or whatever the next great app to come along is.

Darn shame that Ford went with Windows OS on the Sync2 instead of just Android in the first place. It's nowhere near worth it to me to upgrade to Sync3 since it involves hardware too.

Thank you a lot if info there. Probable to complicated for me. I don't even know the firmware # or know how to find it.

thanks again

There's probably some menu on the display that shows the Sync2 version, or if you create an account on Ford's site it will ask for your VIN # and then it will show the last update they "know" about.

If you DIY update it after that it may not show up on their site, and their site is not current, for example mine showed Sync2 version 3.6 while 3.8 and 3.10 had already came out and had some improvements that were not just vehicle specific to other vehicles but apply to most, like handling the A7 or newer nav maps.

Finding the firmware is easy, just Google search for Sync2 3.10 which is the latest. It's roughly a 580MB zip file you download then extract to a USB flash drive formatted to FAT32, then you plug it into the vehicle, turn vehicle engine on and let it sit for up to a half hour while it updates itself.

There are more elaborate instructions on the web but the main thing to watch out for is when you extract the zip file, you don't create a new folder doing so that holds everything, and move that folder to the USB flash drive too. At the root of the flash drive should be at least one file named autoinstall.lst and one folder named SnycMyRide.
