No more GPS after update

Hello, my English is not the best. That’s why using google translator.
I want to do a map update to F.12. I got it from Ford. In part two I always get the error MEM_ERR03. But under settings it says that F12 is on it.
I’ve already done a soft reset and a master reset. But I haven’t had GPS since then. Can the problem be solved somehow?


SYNC Region: EU

Navigation Variant: Nav

Manufacturer Year: MY20

Install Type: OEM

Old SYNC Version: 3.4.21194

New SYNC Version: 3.4.23188

Do you have a error message, if so what is it?

Update Method: Official Ford


This is what I would like you to provide.

  • the autoinstall.lst file Ford pushed your way
  • the . XML file generated by an interrogator log. You can create the tool with Syn3Updater, redact the VIN from the file’s name and content if you care about that (you can open it as a text file).

With that, I will be able to review what’s on the unit and if anything is missing.

I’m a bit loss as to why the nav does not work, since an incomplete upgrade should not do that…

Is the car imported?.

Hi Sandman and thank you. the car ist not importet.

I’m on mobile right now, but based on what I’m seeing, all relevant packages are currently installed on the unit.
That is 14G422-BxK and 14G421-BxK. Other packages are tools.

What is the issue you are currently having?.
Have you performed a master reset?.

I thank you for your time. I did a master reset. I’ve already disconnected the battery. maybe the antenna is defective. I don’t have GPS anymore. can no longer navigate.

Is the unit under warranty?.
Is the car stock?.
Try going into bezel diagnostics to see if the car see the satellites.

I will double check something else, but from the package perspective there’s no reason for your current issue.

EDIT: I’ve double checked that your configuration seems ok, at least at first glance.
Check bezel diagnostics to see if the car can see satellites.

That’s always a possibility. Is it stock?.

hi. the diagnosis says 1-7 satellites. but no glonass GPS satellite. Most of the time only 2 satellites are displayed. could be the antenna. Car still has warranty.

Hi Sandman. Yesterday I removed the Gracenote with cyanlabs. Suddenly GPS works again. But now the woman only speaks English to me. how do I get the language back to German? thank you for your time.

I’m not sure what’s going on, further more, I’m clueless as to why you decided to remove gracenotes.

The issues you are describing has nothing to do with each other. Did you wait some time after the initial upgrade for the car to get GPS lock?.

Reinstall gracenotes since it has nothing to do with the GPS thing.

About the voice, I would not know either, since packages pushed by Ford are correctly installed and are for EU as far as I saw. Check the configuration to see if there’s any specific setting. The UI is in German?.

hi. I’ll run the Ford update again or should I do the USB stick via cyanlabs? had removed Gracenote because I always had the mem err 03. Was that wrong. I haven’t had the GPS signal since December.

Hi Sandman. I reinstalled Gracenote and the navigation language is again in German. And GPS is back too. I have no idea how this all of a sudden works, but it works. Thank you for your patience.

That makes 2 of us: I have no idea what’s the relationship among those issues…
But hey, if it works, it works… :wink:

/fs/rwdata/ = 904M / 1.2G

Close, but maybe created enough room for the temp map files to start? Run the RWData cleaner.

may be. I’m happy because it finally works again. Thanks again.
