Thank you your answers!

Technically yes, but the autoinstall generation doesn’t work correctly currently, it’s being actively worked on.

So i need downgrade, and after again upgrade with NAV, right?

i achieve to update my21 focus to 3.4.21020 + F10 maps with this step.
1- update base app + gracenote + dab logo’s
2- download maps and install (force autoinstall method)
3- download voice and install (force autoinstall method)

as now if you try to update all together will get memory error caused by low free space
as i understood old ford lower than 2020 can install with reformat mode all in one step

If you do not own a MY20/+ model, it’s easier to downgrade and then reformat.
The app will do everything for you, just configure it correctly.


Yes, this is the best way for you to upgrade with your vintage of APIM.
