Australia & New Zealand Next 2020

[Davop]

Hi Bob,
I want to say thank you for the Australia New Zealand Premium Maps. but I'm still stuck.
I unpacked the NAVD file and pasted all files to the root of the USB.
I stated my BMW, inserted the USB in the glove box and nothing happens.
Can anyone give me advise on what I'm doing incorrectly.
When that didn't work, I placed the USB in the console near the AV plug in the USB plug still nothing.
I'm spending hours and hours getting nowhere. Maybe the BMW isn't right?
