I have no first Mazda, if you want you can try this;
I put him in the download content, 10.852.1472547_ECR9.6-CAB-Fuji.cab, ttn patched and ttn_ORI
I've patched the ttn that is within the ttsystem, being an upgrade if you already have installed navcore 10.852.1472547,
it will be difficult to install because your car does not vera as an update, since when installed appears to be
Some files are installed in internal memory,
you can test, put a new SD in the car to see if the firm with TTHome put this new SD and signed by your car if you do the upgrade
would then copy the contents of my Mazda_10.852.1472547_ECR9.6 download and overwrite the SD.
this system to Carminat seems like, you can try if this, remove the loopdir folder to see if the load recreate the new ttsytem ttn.
hope quote, as I said earlier I have not Mazda.
download;
Greetings.
