Good camera, good fit, altough the cable is meters short for a grand scenic 3. Also routing the cable is completely impossible without cutting the cable. Finally, the manual sugests there are more options than were available in the shop.
The camera does it's job, but be carefull that as he is installed in the left numberplate light it does not looks 100% strait.
I did not try, I hope to work when I need it, in my case it will be installed on the renault 2010 along with the computer OEM camera
