For me everything should be cracked in order to get a direct full and free downloads and setups since files are available here without need to get permissions from the Renault house! And it's up to you
. If you have a cracked nnavi.exe file then you have to follow the steps given by MIdev. Otherwise, you should update your map from the toolbox but without modifying the original system files. But if already done, i guess this is the reason why some files couldn't be activated and hidden!! This is just a viewpoint. I hope to hear good news about your case soon 
Best regards
