Freelander 2 Sat Nav 1 dvd or 3 - PLEASE help!

Hi,

I have just bought a 2006 58 plate Freelander 2 and from what I can discover there is only one DVD in the sat nav yet I managed to get a new 2009/2010 set of DVD's fro the Freelander2 and that is a set of three DVD's!

My question is will the set of three work (ie.are they just interchangeable for different parts of Europe) or is there something wrong?

I don't want to break the seal on the DVD's and try in case I need to return them.

Can anyone help?

There are two discs to cover all of Europe and one disc for the UK, so just use the UK one and save the others for your holidays abroad
