How recover maps from corrupted SD?

[GimmickTadpade]

Allow me to present a perplexing situation that has befallen my esteemed Renault Megane III. Recently, I encountered a peculiar issue with the clock application, impeding my ability to adjust the time. In my fervent quest for a solution, I diligently scoured the vast expanse of the internet and stumbled upon the recommendation to update my system. Armed with this knowledge, I embarked upon the noble task of downloading the R Link Toolbox and initiating the update process. However, amidst the fervor of the update, fate intervened in the form of an unforeseen interruption to my internet connection. To my dismay, the R Link Toolbox lamented the corruption of my SD card and promptly initiated a restoration process. Alas, upon the completion of this restoration, my SD card now stands bereft of any semblance of maps, and my once-reliable vehicle refuses to acknowledge its presence altogether.

While the functionality of my vehicle remains intact, it has become apparent that the SD card serves as the vessel solely for the cartographic data. Therefore, I beseech the wisdom of this esteemed community: how might I embark upon the noble quest of recovering my cherished maps and restoring the sanctity of my SD card?
