Renault R-Link : anyway to add POI or update maps ?

Hello all,

I did search everywhere on the forum but didn't find anything about the Renault R-Link (successor of Carminat) :
Is there anything to do with it ? Like add POI or update maps ?
I saw the SD card seems to be proteted : can't be read on windows... :(

Thank you very much in advance !
And thank you for all your work, I got an old Tomtom 750 which is brand you thanks to you ;)
