Oops sorry - I just realised that you really do want a newer set of discs!
The latest (last) available that are compatible are 2011 /2012 - on eBay for under £50 - so instead of having 5 year old info, you can have 2 year old.
Land Rover Freelander 2 UK & *Western Europe Sat Nav Map DVD 3 disc set - 2012 | eBay
I have the same problem with the Becker system as used in the FL1
Out of date discs are not much good really. That's why I now have a Garmin, which I can also use on foot in any unknown city that I might visit.
LandRover as usual have moved on to the latest 'state of the art' technology in their current models and anyone with anything less is left high and dry.
