Golf MK7 Head unit firmware

[WazzaMk7]

Actually I found this was fairly easy to overcome with ODB Eleven.
Go to Control Unit 5F (Multimedia)
> Long Coding

For FM Band
>Byte_9_Band_Settings_FM_Tuner
> Select EU_RdW

For AM Band
> Byte_9_Band_Settings_AM_Tuner
> Select EU_RdW


Apply

I can now scan for all the NZ radio stations from 87.5 t0 108 MHz

Change radio frequency region in MIB1 MIB2 Audi Volkswagen - YouTube

navigation is the one I'm trying to solve which I believe requires the head unit to be updated with NZ / AU region firmware.
