Sorry to butt in- I'm very new to posting messages. I have, from what I can see, a similar issue to yours. My i30 (2015) has an after market (unbeknown to me as I thought I was getting a Hyundai setup) Opal navigation system. I screwed the sd card and have restored a previous backup from my PC to the card. When I put it in the vehicle a message appears "cannot open available files with this licence". I have also copied everything from the CD to the new card and get a different error. All I want to do is get the nav system working again however aus audio (NSW) wants to sell me a card with all the new maps (Q2 - 2021) for $240. Any idea as to how to create a new card using the existing CD?
