The problem is that I want this map Western_and_Central_Europe_2GB_900.4600, but the navi doesn't support SD cards bigger than 2GB
I downloaded Europe_East_900_4602 less than 2GB, but the core doesn't support it
There are 2 options:
- to change the navcore to read 4602, however I might screw up the device
- to change the bootloader to read SD cards bigger than 2 GB

What should I do? I need exactly this parts of the map to make it work
