They should be disabled by default on your device, simply as Garmin no longer store them. Instead they have switched (I think) to some sort of general ‘Danger zone’ warning, which is legal. As I have stuff like this disabled by default, I have no idea what goes on now.
There again, the French have no way of detecting via telepathy, as to whether you are are running speed camera points on your GPS device or not. Even if you got stopped (probably for failure to observe the 12 km speed limit, enforced only on the Feast of the Immaculate Virgin’ and then only in parts of the Gironde) they’d still have to look at your device to establish whether or not you’d transgressed. Chances of being caught? Low to zero. If though you have committed an offence so heinous, that the chief of police is taking an intimate interest in your gps device, I’d suggest that the presence of speed camera markers might be the least of your worries.
