So our 2013 Altima has a nav system that uses an SD card for the map info. Now it has started displaying a message that "No SD card inserted, Please use Nissan Card Only". That card has never been removed from the holder for over 5 years, and now it's failing? I think we can rule out worn contacts, but I did clean the gold fingers, first with a eraser, then isapropal alcohol. Lot's googling show me a few times where they replaced the card and the system started working again. But I'm not about to drop $150 on a new map card unless I know for sure it's going to work.
Apparently cloning the card is not possible, due to a secret electronic serial number on the card. Anyone ever dive into copying one of these cards successfully?
Or is there a way I can verify the existing card still works? I assume if I try to read it via PC/Mac it will want me to format the card.
