HU_NBT2 retrofit

[Celesabc]

Hi

I have a HU_NBT2 retrofitted, everything works now except TCB and I am unable to get a GPS signal.

From posts I read, my factory nbt comes with a usb3 cable for TCB however nbt2 comes with a new adapter for use with TCB2

I can leave without the telematic communications function as only SOS call is supported at where I am located; problem I would like to solve is the GPS signal as I read nbt2 relies on getting it through ATM - TCB2.

Is there a way to code nbt2 to get its GPS signal from the blue input plug located at the back of it which is dedicated for a GPS attena, I have connected my factory blue cable to it but is not working looks like it is still waiting signal from ATM.

I have tried setting SYSTEM_GPS_RECEIVER to aktiv.

Thanks
Cel

I managed to get it solved through following:

HU_NBT2:
SYSTEM_GPS_RECEIVER to aktiv
GPS_FROM_NAVI to aktiv
ADAS_GPS to not_aktiv
TELEMATIC UNIT change from ATM to off (So it fails over to GPS attena)

Hi Cel,

I'm planning to make also retrofit of NBT2 to my 2015 M3, now I have NBT only.

What all is necessary?
Do you have any tutorial for coding?
Any problems with VIN protection?

Thank you in advance for any reply.
