step by step:
1. MMC 1GB fat32 copy two file testmode and NAVI.EXE
2. MMC 4GB fat32 copy MAPS2017
We run the device in mode and look for the file in the directory USER\PRG1\APL\Navi.exe and delete it later copied from the memory card Navii.exe then remove the card and insert with maps. Do I understand correctly?
