W164 ML 320 Command Navigation 5 vs 7 Digit Postcode Entry

[dnamlot]

Does anyone know of a firmware or other software update that could allow 7 rather than the German 5 Digit Postcode entry on the Command Navigation system for an ML320 W164?

I am asking as someone who loves the system and can work around it but it frustrates me every time my wife steals my portable satnav from my A170 in order to enter a postcode.

The only way to do this is to change the Comand system to the NTG 2.5 which supports seven digit postcode input.
