When I brought my VR6 it had the Logic/Conlog alarm fitted it also had a clifford Virtual key thing installed. My insurance only demanded a Cat 2 to be installed so I went to an Alarm fitter by me and asked him to produce a Certificate for me only for the Clifford as I don't know if the logic one was a Cat alarm at the time and my insurance not wanting a Cat 1 didn't need it. Cost about £25 to have one done but my insurance accepted this.
