Yesterday I did the map updates on both my 2016.5 CX-5 and my 2016 MX-5. The CX came with factory nav (warranty is almost up and this is my 3rd update), the MX has nav from the SD card purchased from Amazon and this is the 1st update.
Seems that the Mazda Toolbox needed updating, so that was first on the list and easy.
I inserted the factory card in my PC from my CX first, keeping in mind that this card worked perfectly before this. The first thing that happed is that my PC (Win 10) gave me a warning that the card had issues and would I like the PC to scan and repair those issues? No, don't scan it.
The Toolbox told me that there was a update available and would I like to back up my card and install it? Yes, I would and did. It tool a lil while but the update seemed to be successful, it told me so anyways. But when I checked on the version after the update it told me that I still had an old version and would I like to install the 'new' June 2019 version? Huh? I just did that. I used the Toolbox's diagnostic to check on the card and it told me that my card was invalid. WTF? Now I'm worried. I took that card back out to the CX to see if it would still work in the car, it did but I can't check on the version from the car. I brought the card back in and went through the entire procedure again, same result.
Now I try the same thing on the Amazon nav card for the MX. It works perfectly and as intended. It updates the card and then the Toolbox tells me that the card has the June 2019 updates installed and I'm good to go. It also tells me that I have updates available through 10/2022. I take the card out to the MX and insert it, perfect. But again, there's no way to tell what version it has from the car.
Looks like I'll be spending some quality time on the phone with Mazda Connect today.
