Have a Nissan Qashqai 2013 plate, 16 days after the 3 year warranty expired the Sat Nav stopped recognising the SD data card stating "no SD card recognised please only use genuine Nissan sd card". The card is still the same as the one that came with the car. I contacted Nissan to be advised that they would be able to offer no contribution towards a replacement card and that cards expire after a period of time " every few years", so effectively telling me that every 3 years or so you have to buy a new card to keep your map system working! Pretty sure I have been royally mugged off as now have little choice but to buy an updated card for £125 + vat if I want to use the built in sat nav!
