Hi everyone, my 68 reg Arona could do with a map update. I've seen that you can buy a new V16 card from Amazon for £35 (Navigation AS). Does anyone have experience of these - is it just a case of swapping the cards over? Or is there a foolproof DIY way of doing this without paying £35? I know there have been many posts talking about the procedures but I'm getting lost in the multiple threads about this.
