Howdie simbar. Welcome.
It depends on which console you have ordered. I have the MediaNav rather than the R-Link and the postcode entry on that was only 4 figures, i.e. SG4 1 rather than SG4 1DA so a software upgrade was needed for that (via the renault site / download tool) the rest has been good to go since the off for me. I have not had the 29.9mpg issue other have had here so good luck with that.
I am still enjoying driving this car, i hope you do too.
Which colour combo / spec have you ordered?
