Tom tom Carminat Renault Scenic

hello I have a problem, In my Renault scenic there is a tom tom carminat navigation. The car is 2010 renault scenic. Now I would like to have european card on it. I allready bought new sd card 4Gb. I did the backup of the original SD card in make copy of it. But now when I insert it to the car it says this map cannot be used in this device. I also tried to install the new europe map for tomtom Central_Europe_895_4438 but this doesen't work either. Europe maps were installed by atuomativ installer and patched with lastest patcher, so please can anyone give me information what do I'm doing wrong.

Thanks
