I am deciding whether or not I want to purchase the LI Dual heads for my Mazda 3. I just recently bought the car, and it's pretty much brand new. I was wondering if anybody can describe to me how this unit is installed. Since the car is brand new, I don't want to cause any unnecessary modifications to the car. Will the installer need to drill holes or do any permanent modification to the car to get it installed?
Also, do auto-dealers install these units? I would like to install a killswitch for this unit also, since I drive around the east coast. I would like to switch the LI off when I hit the illegal states, especially Tennessee or South Carolina (Where if you are found with an LI you will be charged with a misdemeanor)
Also, how noticeable is the LI? Is it illegal to get it installed in a state where it's illegal? I want to get it installed in Tennessee and say it's a parking sensor.
