There is a change of system around about that point. Do you have the USB port version or the memory card version? In essence it’s a case of buying the mapping software on whichever media you need and installing it and that should change the radio too. However, with some Japanese versions of cars the tuner is actually different so you may find for radio stations a hardware change is needed
