Hi. Had an issue with upgrading from 3.2 to 3.4 latest. Managed to upgrade, but didn’t installed the navigation files (maps) so now, the Navi doesn’t work, of course. The question is, what do I need to choose to install the maps? Tried with reformat, auto install, and doesn’t work. I get PGK err04. Do I need to choose downgrade and install sync and maps?
SYNC Region: Europe
Navigation Variant: Yes
Old SYNC Version: 3.2
New SYNC Version: Latest
Do you have a error message, if so what is it?
Do not force anything unless you know what you are doing.
The method is up to you.
If you want to reformat the unit and start over, do not force anything and configure syn3updater with your current and desired version, both with maps (does not matter if it’s the same). In the advanced settings tab disable MY20 protection, and set the install mode to “autodetect”. That should create a downgrade USB that will leave you in 3.3 and then reformat the unit with all the packages.
If you do not want to reformat, leave MY20 protection enabled and configure syn3updater with the proper values, and select only upgrade maps.
This should create an autoinstall maps-only upgrade. This should work, but it will be slower as per any other autoinstall process.
