Where can i buy a cheap sat nav for France, Spain and Portugal?

Question

I want to drive from St Malo to Portugal and would like to buy i sat nav does anyone know where i can buy a cheap one as its only for this one time?

Answer 1

E-bay is probably the best place. I live near portugal and the roads are so good here I doubt you'll need a sat nav. If you drive through Madrid it may be good to have one, but I wouldn't go that way if I was driving to Portugal.
