Ford Mustang Rosen Aftermarket System

Hey all, I'm new to the site and have an issue. I lost my original SD Card for my GPS (Long Story, but the short of it is that the original card/software kept freezing/malfunctioning). I've attempted to use downloads to use on my Rosen OE Style Navigation but it would not read the card. I've purchased a card from an alternate source and the update tool recognizes it (NAVIExtras.com) but my unit says "NO SD CARD." Any recommendations? Is the SD Card Slot possibly defective?
