Good day everyone.

Battling on one question for a very long, but still can't figure out how get Australian/New Zealand maps on Japanese CCC unit.
The problem is, I have an imported BMW e90 form Japan with HDD navigation system and HDD unit in the boot (photo attahced) and I really want to get rid of Japanese maps, but don't know how yet.
Please don't tell me that I have to get another CCC unit as local guys claim to do a map update without replacing anything, so my guess is the solution should not be very hard
I have necessary hardware but probably not enough knowledge, please help!!!
