How to update idrive, maps, etc?
I bought a used 2011 135i N55 and I realized the maps may be dated.
I don't see "update" option in settings that exists on my newer 3er.
How do I:
- update to latest available CIC firmware/software
- get latest maps/navigation
- get traffic info (it never shows traffic info)
- latest DCT/ECU stock tune
