How do I update the factory-fitted Amundsen sat-nav in my 2014 Skoda Rapid? We bought the car directly from the original owner in July 2015 (with just 4000 miles on the clock). There should have been an SD card in the document folder, but it wasn't there (we only found out much later). Since we rarely use this car for major journeys, the out of date system has not been a huge issue, hence we've done nothing about it until now. Thanks and regards.
