he does mobile installations
basically he installs all kinds of crazy shit in peoples cars, lights, sirens, gun racks, makes police cars, gov't cars, even did a few helicopters and some police boats, pretty cool stuff really

its a program that interacts with the control box for lights and sirens for cop cars, he customizes what buttons do what, and sets up combos for like when you pull someone over and have lights on but no strobe or siren, or when chasing and its strobe and siren and flashers, it was fun to mess with

so he doesnt get to choose what program to use, its what they buy and he has to install and setup
i do know its a $800 program though

thanks for the help guys, saved me lots of time trying to sort through all the technobabble i was finding on google
