The first one worked great for about 3 weeks and then started a reboot loop when inserted. Gets an error message “Unexpected error — Restarting. And reboots. Bought another card from Nav Kings on eBay and it does the same thing. The cards work on my computer. Let’s me backup, update maps, etc. but when I insert them in the car they don’t work. Just go into the reboot loop. Took the car in to the dealer. They checked it out but could find nothing wrong. They said if I purchase the $399 sd card from them they would guarantee that it will work but not for one purchased from another vendor. Said they don’t know what chip is in the card. Since I use Android Auto it isn’t worth $399 for the Mazda Nav system. I was willing to pay $50-60 for one in case I might be somewhere without cell phone coverage but $399 is pretty steep. I think it is reprehensible of Mazda to sell you a $30,000 automobile that is navigation capable and then hit you up for a $400 sd card to make it functional.

I am still waiting to see if my card will update correctly next time as somebody said there was a recent crackdown on pirated cards (they supposedly won't update). We will see. My card works great right now.
