Possible to update Nav from 5 to 7 digit?

[Alex L]

Hi we have a 2011 C63 with 5 digit postcode entry, is there an update to change this to 7 digit as per the facelift model?

Try comand.co.uk.

Did you find anything on this? I'd be keen to do the same if it's cheap.

Dont think its possible without replacing the unit unfortunately. The full postcode search was part of the comand online option.

Both Mercedes and Command say it isn't possible
