Have used many systems and the 9500ci Radar and Laser Defense System has no equal.
The draw back it needs to be installed by a professional and is rather $$$$$. Most upper end sport cars have these systems installed.
The system is GPS powered so it can be updated and it learns. It talks to you when your approaching Red Light Cameras, Speed Cameras, when it is Laser Shifting if you have jammers installed.
Also has Total Shield Technology which makes this system totally undetectable by any radar detector detector (RDD).
I have seen this system after being installed be totally stealth and integrated into the car layout that you can not even tell its in the car.
The pic is of my display unit....Here is a pic of it during the day.
