Think Sat Nav updates are free at any Hyundai dealership despite the car not being serviced by a Hyundai dealership. Coukd be wrong though. You have to have it booked in and specifically ask for the Sat Nav Update as it's not routinely carried out, even if you are having the car serviced. For information, there is a separate thread within this forum on Sat Nav issues and youy may find your answer there.
