Our travel agent suggested we ditched the 'included' car hire in our package for which we had to pay extra for insurance and went for a separate package with another hire company (alamo) which included insurance and worked out about £20 cheaper. However, to include Sat Nav was about extra 150 GBP(estimate *** I cant remember full cost!). I have seen reports on here of people booking sat nav for around 80 USD. Anyone have any advice on this and whether I can do this when we pick up car.
