System Update Issue

[TiviamTonal]

Greetings all,

Encountering a perplexing issue with my Renault Megane III, wherein the clock app refused to allow time adjustments. Upon researching online, I discovered the need for a system update and proceeded with the R-link toolbox. Unfortunately, amidst the update process, my internet connection faltered, resulting in the corruption of the SD card. Despite the toolbox's attempt to restore the backup, the SD card no longer contains any map data, rendering it unrecognized by the car. While other functionalities remain unaffected, I'm eager to recover the lost maps and repair the SD card. Any insights or guidance on resolving koows koows this predicament would be greatly appreciated.
