Your Navi GPS stands in the car that is your private property... therefore police isn't allowed to look into phone or GPS contents, unless special justice requirement...
And also... - speedcameras are forbidden since approx 2012, but being soon turned into safetycameras detectors, with enlarged hazardous areas ("zones de danger" starting earlier than a radar advice and finishing later too), fully legalized... whenever you did the available software update!!!
So, Navi voices telling you yesterday about a "radar" now says "attention, zone de danger"...
vs my Wikango 600, being but a detector, also bought for my RHD MGTF to show my driving speed in KM/H (digital numbers helping better than the english little characters below the miles ones in my dash).
