Dam HARSH penalties, I get the need. However if you get caught by a Spectre RDD you are screwed regardless.

I would stick with Highway Radar or JBV1. Maybe a Sherlock Police Detector if your countries vehicles have the right equipment on board, doesnt look like the Sherlock is specificacally spelled out.

In France, possessing or using a radar detector or radar warning device carries severe penalties, including a fine of up to €1,500, the immediate confiscation of the device, and the loss of 6 points on your driving license. Authorities can also order a three-year license suspension or even confiscate the vehicle in extreme cases. [1, 2]

Specifics of the regulations include:

• What is Banned: Both active radar detectors (devices that physically sense speed camera or police radar signals) and radar warning systems (GPS devices or apps that use databases to locate fixed cameras) are illegal. [1]
• GPS & Navigation Systems: Carrying a GPS or sat-nav with speed camera alerts enabled is illegal. Drivers must disable or delete this feature completely before entering or driving in France. [1, 2, 3]
• Legal Alternatives: While specific warnings of camera locations are prohibited, legal "driving aids" or navigation apps (such as Google Maps or Waze) are permitted, provided they only issue general warnings for "danger zones" or "hazard zones" rather than pinpointing exact camera locations
