I can answer my own question...it works. I least a Premium AWD in Polymetal Gray with white interior today, put the SD card in and the Navigation came right up. I asked the parts manager about the A suffix and he said that was normal for Mazda with Navigation SD cards. He’s said they change the suffix for slight changes (I’m guessing maybe if they have new maps).
i got it from eBay about a month ago from a seller that quite a few members of a Mazda 3 forum had purchased from. It definitely was worth the $43 gamble for sure!
