Changing maps on Mercedes Benz comand system

Question by posted 1 month ago in Mercedes-Benz

I have a 2010 Mercedes Benz ML350 that I have moved from South Africa to Ireland. I need to change the comand navigation maps from Africa to Europe. I have purchased the latest disk of maps for Europe but the system says it cant read the disk. I took the vehicle to a MB dealer who updated the firmware/software and try to change the maps using their software disk which which is apparently needed along with my map disk. This also did not work - can anyone help.
