hi, i have a 2004 cl600 and don't believe there is a motion detector in our system. is this correct? i had a lincoln mark 8 and that car didn't have a motion detector in the factory alarm system so thieves would just break out a window to gain entry and do their thing. i had a motion detector added for more security. are our cars similar and if so what would be the best way to install a motion detector to our system?
thanks
