I have the HU_H proffessional head unit NBT with NEXT mapping system, car imported used from Japan.
The BMW dealer says it is necessary to have BMW allocate the car VIN to the local country. This has been done by BMW.
The BMW dealer says it is necessary to get a 3rd party to spend a day and $650 with the car to be able to load local maps.
Others with similar Japan market imports have just purchased the map files and put them in via USB stick - lots of examples on Youtube. Done this with files purchased for my VIN.
Somewhere between these two extremes there must be some files or settings I need to complete in order to get the new maps working.
Or the files I have are incorrect. How to identify?
Much discussion with vendor about software version and country zones etc. but no answer why it wont work in my car but works in others.
Does anybody know the exact requirements for HU_H Prof. like:
is the country conversion different on prof. HU vs. the entry HU?
can I get manufacturers info for the HU? I'd like to consider fitting the DAB tuner or buying one from Europe
step by step, has anyone done this can it be acomplished with (a) files on USB like the vendors say "thats all is needed"
(b) E-sys parameter change i.e. "coding" - which items to code?
(c) PSdZ data swap required?
The problem with posting on regular BMW sites is the answers are for F30 etc. the i3 doesnt have DVD drive and the like in the Navi system so these generic posts are not accurate.
Happy to share the changes I've done so far
