Mercedes W204 C220 Comand upgrade
I have recently upgraded the sound and GPS system with a genuine NTG4 COMAND unit from Germany. All works well except the GPS which displays European maps. Is anyone able to provide information on how to replace the existing European maps with Australian maps on the unit's hard drive? I have a Mercedes disc with Australian Maps which I attempted to install, but the Comand unit is unable to read the disc. Any suggestions would be greatly appreciated because MB in Adelaide refuse to assist.
