Thanks for a quick delivery, Installation was easy once I had access to the unit under the seat and took only a few minutes to load the programme. Although this item was a recommended by a friend, I was a little bit worried about the possibility of it damaging my system after enquiring at a Land Rover specialist about online updates. I had no need to worry, as your disc works perfectly. You have saved me a small fortune. It might not be quite as up to date as my TomTom is, but its a lot better than my original Land Rover edition. Thanks for a sensibly priced update for older vehicles. I recommend your services to anyone who has an older SatNav fitted to their car.
