Range Rover Software Update

[Paladin]

I have a 2011 Range Rover. I was wondering how I would go about updating the software that runs both the navigation system and the other automated systems that display on screen.

I have a 2011 Full size Supercharged. I went to My local dealer last year and requested an Update. Land Rover basically Punted me as this nav version was only around for 2 years so is not really Supported.
The dealer did an update but to Be Honest It did not change the look and feel so did not think it was worth it.

Sorry not to have better News.
