2021 GTR. Purchased new card # TD2K 66 EZ1 for USA CAN Mex. Unlocked card and installed after message said to install a card. No screen change after 5 minutes, remove and check that card is in the unlocked position and reinsert but, no change. Went to mail screen and highlighted NAVIGATION BUT, STILL NO CHANGE. Frustrated. What am I doing incorrectly? Ed

I discovered the problem. The slide was not able to move into the full unlock position due to a burr. I used a pen knife to remove the burr and all is well now. It has been a tough year and don't need any more stress. Ed
My CX came with Nav when I bought it but my MX did not. I purchased a Nav card from Amazon for the MX and the first one that was shipped did nothing. I inserted it in the car's card reader with the car off and then started it. It would not recognize the card no matter what I did. I contacted the seller and informed him of what was going on. He wanted me to disconnect the car's battery and try again. I knew that this was pointless, so I told him that I already tried this. He sent me a new card that worked perfectly.

Don't forget to update the maps on your new card after you've driven at least 63 miles. You'll need to install the Mazda Toolbox on your computer first.
