Just called into the Toyota Garage locally (El Ejido, Spain) to order a new DVD for the latest maps for the Sat Nav in the Prius.
170€ ouch!!! Will be here Friday, but seems a lot to me considering the cost of a new portable Sat Nav. Not really sure why buying the upgrade actually as a) we never go anywhere new these days and b) we both have Tom Ton application on the iPhones and a Tom Tom cradle in the Prius!
