hy,
i`ve bought a renault megane 2011 with tomtom build in navigation with SD card however i haven`t got any SD card with the maps.
I`ve read from your forums how to make a SD card from scratch i`ve sucessufully completed all the steps and when i put the SD card into the navi it`s says that the maps can`t be used on this device.

GetMy-CFG v2.53

Maps i`ve tried:
Central_and_Eastern_Europe_885_4009
TomTom.Maps.of.Central.and.Eastern.Europe.v8.35.2419

i patched the PNDnavigator,and activated the maps, after that deleted the file from the loopdir.

The 8.841 can still be patched, so if that step is done correctly it is down to the activation of the map.
Do you have fresh .dct file inside the map folder?

Central_and_Eastern_Europe-512.meta.dct this one?
