Reading last night about how to update the command unit and it seems that it not that easy you need code from Mercedes dealer to activate new unit? Do we have some here that can give me input?
Datacard say
- 509 NAVIBOX
- 523 Radio audio 20
Not understand its this the old unit? Can not fiend any options for backup camera in engineering mode. Why are they still putting this Radio 20 units and not the real NTG?
