Sync 3.4.20351 Update Failing With MEM ERR 03

I tried updating my 2017 escape non nav from 3.4.20282 to 3.4.20351. I keep getting the mem error. I remove grace notes and tried to install. I received the error again. I downgraded and tried again. I am getting the mem error code again. I also did the master reset on the downgrade version. Any ideas on what to do?

My log currently is:

If you are already on 3.3, I would recommend just reformatting to the new version. This will ensure all unnecessary files/packages are removed and you will be left with a clean system.

I tried reformatting and am getting the mem error code when I try to install.

Exactly which mem error are you getting? MEM_ERR03?

Yes, that is the code I keep getting. I tried installing 20282 again. It is giving me that error for that one too. Not sure what’s going on here…

See this tutorial:

Tutorial: Sync 3.4 NON-NAV APIM: Failure to Update to Newer Version Sync 3.4 - Ford / Guides & Info - CyanLabs Official Community

Run the APIM Interrogator and post the storage results from the xml file. It should be similar to this:

NON-NAV 8GB APIM with NAV version 391 Application Voice file installed.
<d2p1:PartitionHealth type="/fs/Nuance/" total=“465M” available=“3.1M”/>

Interesting, seems i broke a localization string, will add to my todo list

I was going to message you about that but forgot…good you caught it. Thanks.

There does not seem to be anything wrong with the APIM or storage that would prevent you from updating. There is plenty of storage and no maps, or other things.

Can you post the log for the updater app?

Go back and review this… Change 3.4 build to newer version - Ford / Sync 3 - CyanLabs Official Community

fixed in upcoming release which adds ROW cut down map packages

This might be a widespread issue. There have been other users who have failed updates due to the certain Gracenotes package selected. Please try and use the 4U5T-14G423-CB package instead. It is specific to NA and half the size of the BB package. You can find it in the software database on this site under F Hub.

Place the downloaded package inside the SyncMyRide folder and use this AutoInstall file.

autoinstall.lst (425 Bytes)

If this install works for you after changing the Gracenotes package, let me know.


I tried that and received the same mem error 3 code.

The files you are using will not work for your application due to storage limitations. the Voice and GN files you selected are EU Global files which will not fit on a NON-NAV North America APIM with 8GB of storage.

Please use:
5U5T-14G381-EM 849Mb Sync3 v3.4.20351
5U5T-14G391-CM 385Mb Sync3 v3.2.20142 (NA ENU,FRC,SPM)

That is interesting as I using the Sync3 updater. I did not pick any files manually… With that being said, how do I do this? I have always used the sync3 updater. I figured out how to download those files from the f hub. I put these files in the syncmyride folder. How do i create/get the autoinstall lst file? Also what about the msa file labeled dontindx.msa?


I haven’t updated the package to use these files BUT this is not what FORD intended! another reason to show why Ford won’t ever update your sync 3.0 units to 3.2+

Sorry for the delay, saw this was not replied to.

CyanLabs has updated the app to source the files you need for your application. Just go back to the app and make sure it shows these files for your update and repeat the process.
