Hello
The principle remains the same, maybe ..., but the file extensions are different and I know where to find for free the updated list of IGO speed cameras for the MZD-Connect until 2017 .... Since 2018 Mazda has changed its hardware and software.
On the old system, speedcams (for France) were added with a speedcam.txt file which was "transformed" into speedcam.spdb and copied to the SD card. There was no france.spc file. There, I have an original france .spc file on the SD card, I don't know what it is for, but apparently it does not contain speed cameras ...
I tried copying the speedcam.spdb and speedcam.txt files (like on the old Mazda system) to my SD card and it doesn't work, the speedcams are not displayed.
