The update IS free for the first 3 years, but even then the dealer will charge for doing it for you. It’s a pain to do, I tried to do it using my MacBook, but it was having none of it. The only way I could get the car to recognise the info on the memory stick, was to use my ancient Windows laptop. I contacted Toyota and was given their Multimedia phone number, it was helpful. 0344 701 6202. Even after the ‘update’, it wasn’t that accurate, you are better off with a TomTom which has FREE updates. I can’t see why Toyota can’t do this.
