Thanks Mark, about the maps, is yours a Japan or UK version car? - just read your other post - UK version may be easier
The BMWi dealer told me its difficult for Japan cars and I have to get them to disconnect the telematics and put the car onto the NZ services first.
Then they get AutoGravity to come in and do the changes. The dealer cannot do it. Seems odd that they would travel to Wellington if they were able to just do it with USB. I may give them a call, the website doesnt cover i3. I suspect some firmware may need changing, might be easier for me to buy a UK NAV system which will also get me the DAB tuner.
I sent the disconnect waiver forms in, all 2 pages, and nothing happened. Other than giving me the ability to buy maps for NZ @ $85, I'm not sure there is anything useful for me.
