Alright just did some research and watched a couple youtube videos on this.
With that being said I just bought a genuine OEM SD card for the GPS navigation for $60 off a ebay seller and it's easy to update using the Mazda Toolbox program which is available for both windows & MAC OSX can be downloaded for free here:

The ebay seller I bought it from is: dbrandshop and they offer free 3 day USPS shipping here in the US. So i should I get the SD card by Friday or Sat at the latest.
