Hi There. I currently have a Freelander 2 and am a member on the freel2.com site. I am now looking to swap it out for a Late model RR2 probably 2010 and 2011 - I've noticed from looking at a few that there seems to be a totally different sat nav/media interface between these model years - does anyone have anymore information about the change? Is it worth going for the later one?

the display used changed in 2012.
2010 and 2011 models used the same software . so you'd have to stretch to a 2012 model to get the latest. Bodsys Brake Bible

Is it worth the stretch? Are they chalk and cheese?

I just swapped across from a 2009 FL2 into a 2012 RRS and yes the SatNav is very different and much better (mind you it is in the last Freelanders as well). Finer, more highly defined graphics if that makes sense and it dims at night (the screen was always too bright at night in the Freelander).
The motorway junctions are shown as you see them on the road which is good but it still does not speak each road name.
The whole interface is just less "clunky" and more up to date.
I think that the hard disk has more countries on it too but I have not really tested that yet.

Thanks for the tip. If you took the sat nav out the equation is the other one OK? I tend to avoid using inbuilt sat nav and use my garmin instead as its so much better.

If you mean "Is the RRS OK compared to the FL2?" then the answer is a resounding "Yes". Its a vast improvement, more refined and powerful and the boot space is much much better. If you get the last of the line you get the 8 speed auto, power tailgate etc which are excellent. My first tank even returned 29mpg which is about the same as would have got out of my Freelander.
Do bear in mind though that the last of the Freelanders were a vast improvement internally on the 2009 example I had.
I bought an RRS HSE Luxury from a main dealer and got two years full on warranty in the deal plus their service has been excellent (its actually gone back for a couple of days for one or two electrical issues to be attended to under warranty but since they delivered a 64 Reg Disco for me to run around in I am not upset).
