Citroen C4 Picasso II 2014 Maps Update Portugal / Spain

Hello,

I just bought a Citroen C4 Grand Picasso II 2014 model with default factory navigation.
I need help with updating the maps and possibly the system/firmware if necessary.
The current system version is: Software: SMEG5.1.F.R4, CD: 25583, Dated: 21-02-14.
Bluetooth version is: Software: 1.2.0, CD: 25583, Dated: 21-02-14.
Map version: Software: DbDw_281/Gr_406, CD: 25583.
Display version: Software: 30.10, CD: 25583, Dated: 21-02-14.

Please I would require assistance with the correct maps version to download for Portugal and Spain with instructions on how to install.
If the system/firmware also needs to be updated please also help with software version/link and instructions. Does the Bluetooth and Display version get updated together with the system firmware update? Are there any known issues/bugs when updating the system firmware?

Thank you very much!

However, it seems that the map you kindly provided was not detected by the system. Thank you again for your generosity, and I am open to any other suggestions or solutions you may have.
