I've bought used Pioneer AVIC F9880DAB headunit (european model). And I would like to update maps in it. I has igo installed:

but the maps are very old like from 2014.

And now my questions:
How can I update maps? I have 2022.Q4s map on my PC and I would like to transfer those onto the unit. The unit only has 2xUSB on the back, it doesn't have any slot for microsd card. It tells me to install AVICSYNC app but I can't see on google play. I've found an apk on google but after installing it tells me "the application is not licensed" and turns off

Does anyone have any idea what should I do, if it's even possible to update the maps in this case? Thanks in advance

EDIT: I installed Naviextras Toolbox and synced usb pendrive in navigation setting in the unit but it shows that I can buy new maps


In the updates tab I can only reinstall my old maps



File explorer shows what's on the usb memory



i wonder if I copy my maps there and a license file it'll work
